[root@localhost asterisk]# cat sip.conf
;
; SIP Configuration example for Asterisk
;
; Syntax for specifying a SIP device in extensions.conf is
; SIP/devicename where devicename is defined in a section below.
;
; You may also use
; SIP/username@domain to call any SIP user on the Internet
; (Don't forget to enable DNS SRV records if you want to use this)
;
; If you define a SIP proxy as a peer below, you may call
; SIP/proxyhostname/user or SIP/user@proxyhostname
; where the proxyhostname is defined in a section below
;
; Useful CLI commands to check peers/users:
;   sip show peers		Show all SIP peers (including friends)
;   sip show users		Show all SIP users (including friends)
;   sip show registry		Show status of hosts we register with
;
;   sip debug			Show all SIP messages
;
;   reload chan_sip.so		Reload configuration file
; 				Active SIP peers will not be reconfigured

				; in the this section to get any video support at all.
				; You can turn it off on a per peer basis if the general
				; video support is enabled, but you can't enable it for

 		    		; for any reason, always reject with '401 Unauthorized'
 				; instead of letting the requester know whether there was
 				; a matching user or peer for their request

;g726nonstandard = yes		; If the peer negotiates G726-32 audio, use AAL2 packing
				; order instead of RFC3551 packing order (this is required
				; for Sipura and Grandstream ATAs, among others). This is
				; contrary to the RFC3551 specification, the peer _should_
				; be negotiating AAL2-G726-32 instead :-(

;matchexterniplocally = yes     ; Only substitute the externip or externhost setting if it matches
                                ; your localnet setting. Unless you have some sort of strange network
                                ; setup you will not need to enable this.

;
; If regcontext is specified, Asterisk will dynamically create and destroy a
; NoOp priority 1 extension for a given peer who registers or unregisters with
; us and have a "regexten=" configuration item.
; Multiple contexts may be specified by separating them with '&'. The
; actual extension is the 'regexten' parameter of the registering peer or its
; name if 'regexten' is not provided.  If more than one context is provided,
; the context must be specified within regexten by appending the desired
; context after '@'.  More than one regexten may be supplied if they are
; separated by '&'.  Patterns may be used in regexten.
;
;regcontext=sipregistrations
;
;--------------------------- RTP timers ----------------------------------------------------
; These timers are currently used for both audio and video streams. The RTP timeouts
; are only applied to the audio channel.
; The settings are settable in the global section as well as per device
;
;rtptimeout=60			; Terminate call if 60 seconds of no RTP or RTCP activity
				; on the audio channel
				; when we're not on hold. This is to be able to hangup
				; a call in the case of a phone disappearing from the net,
				; like a powerloss or grandma tripping over a cable.
;rtpholdtimeout=300		; Terminate call if 300 seconds of no RTP or RTCP activity
				; on the audio channel
				; when we're on hold (must be > rtptimeout)
;rtpkeepalive=<secs>		; Send keepalives in the RTP stream to keep NAT open
				; (default is off - zero)
;--------------------------- SIP DEBUGGING ---------------------------------------------------
;sipdebug = yes			; Turn on SIP debugging by default, from
				; the moment the channel loads this configuration
recordhistory=no		; Record SIP history by default
				; (see sip history / sip no history)
;dumphistory=yes		; Dump SIP history at end of SIP dialogue
				; SIP history is output to the DEBUG logging channel

;--------------------------- STATUS NOTIFICATIONS (SUBSCRIPTIONS) ----------------------------
; You can subscribe to the status of extensions with a "hint" priority
; (See extensions.conf.sample for examples)
; chan_sip support two major formats for notifications: dialog-info and SIMPLE
;
; You will get more detailed reports (busy etc) if you have a call limit set
; for a device. When the call limit is filled, we will indicate busy. Note that
; you need at least 2 in order to be able to do attended transfers.
;
; For queues, you will need this level of detail in status reporting, regardless
; if you use SIP subscriptions. Queues and manager use the same internal interface
; for reading status information.
;
; Note: Subscriptions does not work if you have a realtime dialplan and use the
; realtime switch.
;
allowsubscribe=yes		; Disable support for subscriptions. (Default is yes)
;subscribecontext = default	; Set a specific context for SUBSCRIBE requests
				; Useful to limit subscriptions to local extensions
				; Settable per peer/user also
notifyringing=yes		; Notify subscriptions on RINGING state (default: no)
notifyhold=yes			; Notify subscriptions on HOLD state (default: no)
				; Turning on notifyringing and notifyhold will add a lot
				; more database transactions if you are using realtime.
limitonpeers=yes		; Apply call limits on peers only. This will improve
limitonpeer=yes
				; status notification when you are using type=friend
				; Inbound calls, that really apply to the user part
				; of a friend will now be added to and compared with
				; the peer limit instead of applying two call limits,
				; one for the peer and one for the user.
				; "sip show inuse" will only show active calls on
				; the peer side of a "type=friend" object if this
				; setting is turned on.

;----------------------------------------- T.38 FAX PASSTHROUGH SUPPORT -----------------------
;
; This setting is available in the [general] section as well as in device configurations.
; Setting this to yes, enables T.38 fax (UDPTL) passthrough on SIP to SIP calls, provided
; both parties have T38 support enabled in their Asterisk configuration
; This has to be enabled in the general section for all devices to work. You can then
; disable it on a per device basis.
;
; T.38 faxing only works in SIP to SIP calls, with no local or agent channel being used.
;
t38pt_udptl=no            ; Default false
;
;----------------------------------------- OUTBOUND SIP REGISTRATIONS  ------------------------
; Asterisk can register as a SIP user agent to a SIP proxy (provider)
; Format for the register statement is:
;       register => user[:secret[:authuser]]@host[:port][/extension]
; If no extension is given, the 's' extension is used. The extension needs to
; be defined in extensions.conf to be able to accept calls from this SIP proxy
; (provider).
;
; host is either a host name defined in DNS or the name of a section defined
; below.
;
; Examples:
;
;register => 1234:password@mysipprovider.com
;
;     This will pass incoming calls to the 's' extension
;
#include snep/snep-sip-trunks.conf
;
;register => 2345:password@sip_proxy/1234
;
;    Register 2345 at sip provider 'sip_proxy'.  Calls from this provider
;    connect to local extension 1234 in extensions.conf, default context,
;    unless you configure a [sip_proxy] section below, and configure a
;    context.
;    Tip 1: Avoid assigning hostname to a sip.conf section like [provider.com]
;    Tip 2: Use separate type=peer and type=user sections for SIP providers
;           (instead of type=friend) if you have calls in both directions

;registertimeout=20		; retry registration calls every 20 seconds (default)
;registerattempts=10		; Number of registration attempts before we give up
				; 0 = continue forever, hammering the other server
				; until it accepts the registration
				; Default is 0 tries, continue forever

;----------------------------------------- NAT SUPPORT ------------------------
; The externip, externhost and localnet settings are used if you use Asterisk
; behind a NAT device to communicate with services on the outside.

externip=177.101.123.229	; Address that we're going to put in outbound SIP
				; messages if we're behind a NAT

				; The externip and localnet is used
				; when registering and communicating with other proxies
				; that we're registered with
;externhost=voip.opens.com.br	; Alternatively you can specify an
				; external host, and Asterisk will
				; perform DNS queries periodically.  Not
				; recommended for production
				; environments!  Use externip instead
;externrefresh=10		; How often to refresh externhost if
				; used
				; You may add multiple local networks.  A reasonable
				; set of defaults are:
localnet=192.168.21.0/255.255.255.0; All RFC 1918 addresses are local networks

; The nat= setting is used when Asterisk is on a public IP, communicating with
; devices hidden behind a NAT device (broadband router).  If you have one-way
; audio problems, you usually have problems with your NAT configuration or your
; firewall's support of SIP+RTP ports.  You configure Asterisk choice of RTP
; ports for incoming audio in rtp.conf
;
nat=auto_comedia		; Global NAT settings  (Affects all peers and users)
                                ; yes = Always ignore info and assume NAT
                                ; no = Use NAT mode only according to RFC3581 (;rport)
                                ; never = Never attempt NAT mode or RFC3581 support
				; route = Assume NAT, don't send rport
				; (work around more UNIDEN bugs)

;----------------------------------- MEDIA HANDLING --------------------------------
; By default, Asterisk tries to re-invite the audio to an optimal path. If there's
; no reason for Asterisk to stay in the media path, the media will be redirected.
; This does not really work with in the case where Asterisk is outside and have
; clients on the inside of a NAT. In that case, you want to set canreinvite=nonat
;
canreinvite=no			; Asterisk by default tries to redirect the
				; RTP media stream (audio) to go directly from
				; the caller to the callee.  Some devices do not
				; support this (especially if one of them is behind a NAT).
				; The default setting is YES. If you have all clients
				; behind a NAT, or for some other reason wants Asterisk to
				; stay in the audio path, you may want to turn this off.

				; In Asterisk 1.4 this setting also affect direct RTP
				; at call setup (a new feature in 1.4 - setting up the
				; call directly between the endpoints instead of sending
				; a re-INVITE).

;directrtpsetup=yes		; Enable the new experimental direct RTP setup. This sets up
				; the call directly with media peer-2-peer without re-invites.
				; Will not work for video and cases where the callee sends
				; RTP payloads and fmtp headers in the 200 OK that does not match the
				; callers INVITE. This will also fail if canreinvite is enabled when
				; the device is actually behind NAT.

;canreinvite=nonat		; An additional option is to allow media path redirection
				; (reinvite) but only when the peer where the media is being
				; sent is known to not be behind a NAT (as the RTP core can
				; determine it based on the apparent IP address the media
				; arrives from).

;canreinvite=update		; Yet a third option... use UPDATE for media path redirection,
				; instead of INVITE. This can be combined with 'nonat', as
				; 'canreinvite=update,nonat'. It implies 'yes'.

;----------------------------------------- REALTIME SUPPORT ------------------------
; For additional information on ARA, the Asterisk Realtime Architecture,
; please read realtime.txt and extconfig.txt in the /doc directory of the
; source code.
;
rtcachefriends=yes		; Cache realtime friends by adding them to the internal list
				; just like friends added from the config file only on a
				; as-needed basis? (yes|no)

rtsavesysname=yes		; Save systemname in realtime database at registration
				; Default= no

rtupdate=yes			; Send registry updates to database using realtime? (yes|no)
				; If set to yes, when a SIP UA registers successfully, the ip address,
				; the origination port, the registration period, and the username of
				; the UA will be set to database via realtime.
				; If not present, defaults to 'yes'.
rtautoclear=no			; Auto-Expire friends created on the fly on the same schedule
				; as if it had just registered? (yes|no|<seconds>)
				; If set to yes, when the registration expires, the friend will
				; vanish from the configuration until requested again. If set
				; to an integer, friends expire within this number of seconds
				; instead of the registration interval.

ignoreregexpire=yes		; Enabling this setting has two functions:
				;
				; For non-realtime peers, when their registration expires, the
				; information will _not_ be removed from memory or the Asterisk database
				; if you attempt to place a call to the peer, the existing information
				; will be used in spite of it having expired
				;
				; For realtime peers, when the peer is retrieved from realtime storage,
				; the registration information will be used regardless of whether
				; it has expired or not; if it expires while the realtime peer
				; is still in memory (due to caching or other reasons), the
				; information will not be removed from realtime storage

;----------------------------------------- SIP DOMAIN SUPPORT ------------------------
; Incoming INVITE and REFER messages can be matched against a list of 'allowed'
; domains, each of which can direct the call to a specific context if desired.
; By default, all domains are accepted and sent to the default context or the
; context associated with the user/peer placing the call.
; Domains can be specified using:
; domain=<domain>[,<context>]
; Examples:
; domain=myasterisk.dom
; domain=customer.com,customer-context
;
; In addition, all the 'default' domains associated with a server should be
; added if incoming request filtering is desired.
; autodomain=yes
;
; To disallow requests for domains not serviced by this server:
; allowexternaldomains=no

;domain=mydomain.tld,mydomain-incoming
				; Add domain and configure incoming context
				; for external calls to this domain
;domain=1.2.3.4			; Add IP address as local domain
				; You can have several "domain" settings
;allowexternaldomains=no	; Disable INVITE and REFER to non-local domains
				; Default is yes
;autodomain=yes			; Turn this on to have Asterisk add local host
				; name and local IP to domain list.

; fromdomain=mydomain.tld 	; When making outbound SIP INVITEs to
                          	; non-peers, use your primary domain "identity"
                          	; for From: headers instead of just your IP
                          	; address. This is to be polite and
                          	; it may be a mandatory requirement for some
                          	; destinations which do not have a prior
                          	; account relationship with your server.

;------------------------------ JITTER BUFFER CONFIGURATION --------------------------
; jbenable = yes              ; Enables the use of a jitterbuffer on the receiving side of a
                              ; SIP channel. Defaults to "no". An enabled jitterbuffer will
                              ; be used only if the sending side can create and the receiving
                              ; side can not accept jitter. The SIP channel can accept jitter,
                              ; thus a jitterbuffer on the receive SIP side will be used only
                              ; if it is forced and enabled.

; jbforce = no                ; Forces the use of a jitterbuffer on the receive side of a SIP
                              ; channel. Defaults to "no".

; jbresyncthreshold = 1000    ; Jump in the frame timestamps over which the jitterbuffer is
                              ; resynchronized. Useful to improve the quality of the voice, with
                              ; big jumps in/broken timestamps, usually sent from exotic devices
                              ; and programs. Defaults to 1000.

; jbimpl = fixed              ; Jitterbuffer implementation, used on the receiving side of a SIP
                              ; channel. Two implementations are currently available - "fixed"
                              ; (with size always equals to jbmaxsize) and "adaptive" (with
                              ; variable size, actually the new jb of IAX2). Defaults to fixed.

; jblog = no                  ; Enables jitterbuffer frame logging. Defaults to "no".
;-----------------------------------------------------------------------------------

[authentication]
; Global credentials for outbound calls, i.e. when a proxy challenges your
; Asterisk server for authentication. These credentials override
; any credentials in peer/register definition if realm is matched.
;
; This way, Asterisk can authenticate for outbound calls to other
; realms. We match realm on the proxy challenge and pick an set of
; credentials from this list
; Syntax:
;	auth = <user>:<secret>@<realm>
;	auth = <user>#<md5secret>@<realm>
; Example:
;auth=mark:topsecret@digium.com
;
; You may also add auth= statements to [peer] definitions
; Peer auth= override all other authentication settings if we match on realm

; Definitions of locally connected SIP devices
;
; type = user	a device that authenticates to us by "from" field to place calls
; type = peer	a device we place calls to or that calls us and we match by host
; type = friend two configurations (peer+user) in one
;
; For device names, we recommend using only a-z, numerics (0-9) and underscore
;
; For local phones, type=friend works most of the time
;
; If you have one-way audio, you probably have NAT problems.
; If Asterisk is on a public IP, and the phone is inside of a NAT device
; you will need to configure nat option for those phones.
; Also, turn on qualify=yes to keep the nat session open
