> 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
