outgoing sched_transfer and convert incoming call number to

HI hope someone could help I have two task that I can not achieve

1- I have set an inbound route for only one DID. what I want to do this is that the incoming call like [email protected] instead of detect like this transfer or bridge the call but instead of the number that is calling  convert to the extension number  example [email protected]  this way my gsm gateway can dial apropiate number which is not dialing correctly since the call appears like [email protected] even the fact that it has already being transfered to 190 ext

2- I have a gateway that send calls from FusionPbx (192.168.3.100) to this gsm gateway (192.168.3.40)

  this is the scenario.
  An incoming call enter fusionPbx then it ring a ring group with 3 extensions 2 locals and the gsm gateway that dial my cel.  this gsm gateway has a chip (mexico telcel ) which can have 3 numbers that are free for 5 minutes then it cost per minute.  so I succesful did a dialplan that count 4.5 minutes then it put the call in hold for 4 sec hangup with the gateway and after 4 sec it re-connect the call to cel again. this is a loop that can last forever until i hangup. so no problem here the dialplan

condition 	  destination_number 	  ^105$
   action 	  sched_transfer 	  +265 142 XML default

the conference room that hold the call is

 condition 	  destination_number 	  ^142$
 action 	  sched_transfer 	  +4 105 XML default
 action 	  answer
 action 	  playback 	  /usr/local/freeswitch/recordings/recording1.wav
 action 	  conference 	  Conference-2-192.168.3.100@default

this work like a charm for inbound calls

what I have not yet is the opposite.....  when I from my cel phone call my gsm gateway to connect to fusionpbx and dial out but ALL outbound call I do to put in this same loop  4.5 minutes then send the call to conference room then the system knows to hold the call an re-connect......... any idea on how to achieve this ?  remember the gateway is in 192.168.3.40
I had this this but dont work

condition 	  ${sip_from_uri} 	  ^[email protected]:5060$
condition 	  destination_number 	  ^(\d{8,14})$
action 	  sched_transfer 	  +26 142 XML default
