[OpenSIPS-Users] Presence BLF TLS

Mon May 27 19:05:26 CEST 2013

Hello Chusov,

The presence modules disable the opening of new TCP conns for sequential
requests (like NOTIFIES) as they follow the same TCP conn as the SUBSCRIBE.

What I see on your trace is that SUBSCRIBE comes from 10.222.1.253:37827
, but the advertised address in Contact hdr is
sip:9999 at 10.222.1.253:5060  - a different port, which will prevent the
re-usage of the same TCP connection.

What you can do is to force the re-usage of the existing TCP conn (from
SUBSCRIBE) by using the global parameter:
    tcp_accept_aliases = 1
