    https://issues.asterisk.org/jira/browse/ASTERISK-24459


Repository: Asterisk


Description
-------

A native rtp bridge was being chosen (it shouldn't have been) when using two pjsip channels with incompatible DTMF modes.  This patch sets the rtp instance property, AST_RTP_PROPERTY_DTMF, for the appropriate DTMF mode(s) for pjsip.  It was not being set before, meaning all DTMF modes for pjsip were being treated as compatible, thus native bridging would be chosen as the bridge type when it shouldn't have been.

Diff: https://reviewboard.asterisk.org/r/4265/diff/


Testing
-------

Using pjsip, set up two endpoints with incompatible DTMF modes.  After establishing a call between noted, using the CLI, that that a native_rtp bridge was being chosen. After the patch noted the channels were now in a simple bridge.


Thanks,

Kevin Harwell
