No audio Classic Extension or SIP URI

I have an account set up and I can npot seem to pass audio from I-P-Tel server to a SER.

I have a trunk set up to the SER. IPTEL registers fine. I have established a classic extension via this trunk

I also Set up a SIP Extension that simply forwards to a URI on the SER such as SIP/account@ipaddress. The SER then forwards to a PSTN number

Whether I dial from a UA directly to the destination number or through either of the above extensions, whether classic or SIP, there is no audio. In some instance s I hear a ring back. All cases the SER logs show the call was connected. There is no firewall on the SER.

It appears , somehow the two are not effectively negotiating media ports??

I have tried audio bypass on and off on both the extension as well as the trunk

I have this same server set up on a trunk opn a separate account. Last I tested , it was working. I will post here the results of the tests on the other account.

Yes it appears that the IPtel server is not passing audio to and from the SER, however I have tested with other trunks, and it works fine. The odd part is i can dial out to the trunk from an extension and connect fine. The problem appears to be when sending to a SIP URI or a classix extension

Alternate trunks tested fine, but not my SER based trunk!

RE: No audio Classic Extension or SIP URI

Hi Mark,

what a strange case that you have discovered. Please try again after resaving your extension. I have improved dialing classical extensions.

Thanks,
Pascal

It did NOT do the trick, and I am at a loss for tricks on my end.
