OK, been messing with Asterisk for a long time and I have my opinion on where the issues lies but sometimes it's just nice to see what others think that can relate

Here goes..


Inbound calls flow like this:
Tier 1 Provider (SIP) > Asterisk 1.8 > Name Brand PBX - Calls work fine


Outbound calls flow like this:
Name Brand PBX > Asterisk 1.8 > Tier 1 provider (SIP) - Calls work fine




Problem is being reported on that many (not all) calls have no audio when they are forwarded.


Example of forwarded call:
Inbound call comes in from Tier 1 Provider > Asterisk 1.8 > Name Brand PBX


Name Brand PBX then forwards the call back out to users cell phone:
Name Brand PBX > Asterisk 1.8 > Tier 1 provider


No audio a large percentage of the time.




It's my opinion that the Asterisk box only sees the forwarded call as a regular outbound call and forwards it on to the Tier 1 provider then to the users cell phone.


I don't see how Asterisk even knows or cares if it was forwarded within the Name Brand PBX. The Name Brand PBX is the one making the connection of the inbound and outbound call. All other inbound and outbound calls are fine, audio is only lost when the Name Brand PBX connects the two calls and creates the forward.


Thoughts?

Asterisk does not need to care.  Is it SIP all the way through?


Thanks,

Any chance this is a simple directmedia and/or NAT issue?
