Joshua Colp commented on ASTERISK-26339:
----------------------------------------

Thanks for the report and debug. However we also need protocol specific debug captured at the time of the issue. Please include the following:

* Asterisk log files generated using the instructions on the Asterisk wiki [1], with the appropriate protocol debug options enabled, e.g. 'pjsip set logger on' if the issue involves the chan_pjsip channel driver.
* Configuration information for the relevant channel driver, e.g. pjsip.conf.
* A wireshark compatible packet capture, captured at the same time as the Asterisk log output.

> think about this scenario.
> Alice call in asterisk. Asterisk dialplan answer Alice and then playback "welcome and wait to dial Bob", then dialplan dial Bob. When Bob answer the call and bridge to Alice, the codec of Alice channel read/write direction are not same.
> something like this:
> Alice========Asteriks==========Bob
> -----G729---------->answer
> <----G729-----------playback
>                              dial 
>                                      ----------ulaw-------->
>                                     <--------ulaw---------
> --------G729-------->bridged
> <---------ulaw-------
> this scenario will cause oneway voice on Dialogic Gateway.
