Additional context

[razvancrainea]

Can this be reproduced for every call, or does it happen once in a while?

[QuincyGao]

Yes, every Call can reproduce.

[razvancrainea]

How do you define you rtpengine nodes? through script, or db?

[QuincyGao]

like this: modparam("rtpengine", "rtpengine_sock", "udp:172.16.4.111:22222")

[razvancrainea]

I've just pushed a fix for this - can you please give it another try and let me know if you're still having trouble?

[QuincyGao]

ok, thanks, I will try it later.

[QuincyGao]

I checked the code twice and unfortunately the problem is still there.

the sceen is that:
1007 register on opensips(172.16.4.111:5360), 1008 register on fs(172.16.4.114:5080).
the 1007 call 1008 , then 1008 answer, then the error occurs.
