[asterisk-bugs] [JIRA] (ASTERISK-25498) Asterisk crashes when negotiating g729 without that module installed

[Ben Langfeld (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-25498?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=228455#comment-228455 ] 

Ben Langfeld commented on ASTERISK-25498:
-----------------------------------------

The SDP for the call with channel `SIP/lsi-0000da6c` was:

{noformat}
v=0
o=- 44909901933898 44909901933899 IN IP4 10.0.6.10
s=-
c=IN IP4 10.0.6.10
t=0 0
m=audio 63632 RTP/AVP 18 0 101
a=rtpmap:101 telephone-event/8000
a=ptime:20
{noformat}

This indicates G.729 and G.711 PCMU. The AMD log line states `(Fmt: ulaw)`. I'm not sure why something attempts to use G.729 here.
