[asterisk-bugs] [JIRA] (ASTERISK-30275) ari: RTP packets being sent out of P2P with out of stream seqno/ts with early bridging

[Joshua C. Colp (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-30275?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=260599#comment-260599 ] 

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

I believe this is specifically limited to ARI, and its use of early media. Not early media over all within Asterisk. I think it's possible for packets to get sent out of the P2P mechanism for a brief period of time.

> 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
