| Description: | When a call is inbound from a SIP trunk, the ousside caller hears silence while the SLATrunk(xxx) is executing and the SLAStations are ringing. All other inbound SIP calls return a ringback to the caller. ****** ADDITIONAL INFORMATION ****** I reported the exact symtoms about a year ago on issue # 9719, after some back and forth it was suggested to change progresinband to "yes". This solved the problem. I recently converted the system to 1.4.19 and the problem has returned. No media appears to be flowing toward the caller while the stations are ringing. Upon answer, everything works fine. This is true whether the call arrives on a SIP trunk or originates from a local station. I see in some release notes that MOH can now be substituted in place of ringback, is it possible that ringback in no longer the default? I can find no documents to explain how this new feature is configured. | ||

By: Mike Thomas (mthomasslo) 2008-04-17 14:34:06 yes, I'm going to send a dump of a sample call in a moment. By: Monte (spirited) 2008-08-11 11:41:40 I am having same issue with interop testing. Engineers said that Asterisk is 'sitting in middle' and not sending its own ringback when connecting with certain GW's. Failure to send 183... any fix on this? By: Russell Bryant (russell) 2008-12-09 11:09:50.000-0600 I have been able to reproduce the issue. I will work on a fix now.

We need to make sure that we don't start writing audio to the trunk channel until we're actually ready to answer it. Otherwise, the channel driver will treat it as inband progress, even though all they are getting is silence.
