[SR-Users] Help with KEEP-ALIVE method

[Sergey Basov]

Hi All.

Today I have problem with connection from 1 of the clients.
Their PBX sends KEEP-ALIVE after some time after REGISTER.

I have next error in kamailio log

Feb 28 14:26:19 sbc2 /usr/sbin/kamailio[3657]: ERROR: <core>
[tcp_read.c:1354]: tcp_read_req(): bad request, state=7, error=4
buf:#012KEEP-ALIVE sip:1.2.3.4 SIP/2.0#015#012#015#012#012parsed
:#012KEEP-ALIVE sip:1.2.3.4 SIP/2.0

After which my kamailio closes TCP session....

This connection is done with sip TLS.

Thank you in advance.
