Call Forwarding issue (DAHDI)

General Help
1

Hello,

I have a FreePBX 2.10 server that is linked to our Alcatel 4400 PBX.

I have just noticed that if someone rings an Alcatel extension and that extension is forwarded to another Alcatel extension the call fails. For some reason the forwarding request comes back to FreePBX with the correct number but it tries to forward it locally rather than back down the trunk. The call therefore fails with an no service.

Here is CLI info from an IP phone (3001) ringing an Alcatel extension (7909) that’s on a NoReply to 5004 (also an Alcatel Extension)

Any help or advice would be greatly appreciated.

I have this same issue… did you find resolution? I’m looking at putting in a special dialplan in the from-custom-trunk context, but not sure where to start. Any help would be appreciated.

I did fix it but to be honest I can’t remember how. There have been a lot of quirky things that i’ve learnt and overcome while developing my system. Something to try would be to check what encoding you have. I had QSIG at the time but recently changed to QSIG/ABC_F to take advantage of more features on the alcatel side from the IP. This cleared up a lot of issues (but also introduced some new ones). My setup is slightly more complicated due to there being 2 cisco routers joining the Alcatel to Asterisk. about 98% of all of my problems were Cisco config related.

My encoding is QSIG. The only other option is ISDN for encoding. We don’t have an Alcatel switch on the other end - I think ours is an NEC with NEAX 2400 IPX circuit card.

It depends how the tie trunk’s context is if it is from-pstn then it won’t have access to internale contexts, try from-internal to start.
