Hello all,<br>
<br>
we have a problem with re-invites passing through sipwise during a<br>
call, kamailio-proxy sends out correct packet, but kamailio-lb seems<br>
like it cuts out a few characters in the end and therefore it does not<br>
get recognized and replied in PBX, the packet is also not visible in<br>
wireshark. I don't see any errors in kamailio-lb logs though. What<br>
could be the cause of that?<br>
<br>
Here's a ngrep-sip of the re-invite:<br>
