    [ https://issues.asterisk.org/jira/browse/ASTERISK-30275?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=260487#comment-260487 ] 

Joshua C. Colp commented on ASTERISK-30275:
-------------------------------------------

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.

Please also attach a packet capture.

>             Project: Asterisk
>          Issue Type: Bug
>      Security Level: None
>          Components: Bridges/bridge_native_rtp
>    Affects Versions: 18.9.0, 18.12.1, 18.15.0
>         Environment: Ubuntu 22.04
> Ubuntu 20.04
>            Reporter: John M
>            Severity: Major
>
> 1. It only happens on the caller channel.
> 2. The issue only happens when using the bridge_native_rtp.so locally
> 3. The issue doesn’t happen if I set directmedia=yes and native_rtp is remote since Asterisk doesn't pass RTP in this case.
> 4. The issue doesn’t happen if I do noload => bridge_native_rtp.so and use only simple_bridge.
> 5. The issue seems to also only happen during early bridging. If early bridging is not used the issue doesn't seem to happen.
> Issue is detailed here: https://community.asterisk.org/t/asterisk-sending-rtp-with-wrong-sequence-number/94468
