Hello!
Sorry to bring the topic up, but so far I have no idea what the problem
is. Or do I need to open an issue on github?

Hello!
I'm trying to build a classic anycast cluster topology with two
OpenSIPS nodes, in which requests are processed by one proxy and
responses by another.
The client and server are emulated via baresip.
But I ran into a problem in that the replicated responses have an
extra 00 in the tail of the reply (the original reply from baresip
UAS does not have it).
