Hello all.

I have an NEC PBX connected via a TE210p E1 line to an asterisk 1.6 box.

NEC -> E1 -> TE210P:1 -> * -> TE210P:2 -> E1 -> Telco

Incomming calls from the telco to the asterisk box to the NEC work
 fine with indials and everything.  Works sweet.

Outbound from the NEC to the Asterisk box fail.  Giving an long dial
 tone that then times out.

Ie, pick up NEC handset, dial to get outside line, are given a dial tone,
 and then press numbers on keypad but dialtone continues and then
 eventually get an fast busy signal.

Looking at the console, it doesn't seem like the * system is seeing the
 dialed number data from the NEC box. the reason I say this is that
 the asterisk box complains that it is accepting call from '' to ''

Which just seems like no data is passing across.

It is an NEC Xen Master that is configured to connect to an E1 and works
fine. This E1 line has been replaced by a direct link to the * box to make
 the NEC box think the * box is the Telco – so I know this at least works.
 And I can also send a call into the NEC system fine.

Does anyone know how to debug this? How can I see what data the NEC
 box is sending over the signaling channel in * ?
