             Summary: asterisk 13.4.0 fails to transcode calls to/from g729 with TCE400P
                 Key: ASTERISK-25197
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-25197
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
    Affects Versions: 13.4.0
         Environment: SLES 11 SP3 (3.0.101-0.47.52-default x86_64)
            Reporter: Tom Parker


With the TCE400P installed a call placed from a Polycom SIP phone using ulaw to a SIP trunk using g729 succeeds but audio is only one way.  The caller does not hear any audio but the callee can.  

This also happens between two phones on the same asterisk pbx if one phone is forced to use ulaw and the other g729.  In this scenario the caller does not receive any audio from the callee.

Downgrading asterisk to 11.13 has fixed the problem for me with no change at all in my configuration or sip setup for my telephones.
