Hey Daniel,
Yes, I'm familiar with the methods sipcapture uses, I don't use HEP, using raw socket capture, I think this may be a sipcapture issue, debuging kamailio shows normal startup and processing of UDP SIP packets, but does not show any activity with TCP packets. I have enabled/disabled the different capture methods and no TCP SIP packets are processed. Also, I didn't mention before I'm testing on 2 different instances, one is a Homer 3.5 (Kamailio 4.1.2) and another is Homer 5.0 (Kamailio 4.4.0). I'll post to the Homer list and see what they say.
Thanks.
JR
is it this about a sipcature node? If yes, then it receives the packets over HEP, meaning that is not going to the normal processing path. Kamailio detects it is not a SIP packet, executes some callbacks for non-sip packets registered by modules (in this case sipcapture). The module detecting it's a packet for it, can execute the request_route once it builds a local sip packet.
To troubleshoot further, run with debug=3 in kamailio.cfg and see what you get in the logs.
Cheers, Daniel

Thanks.

I assume you have ruled out firewall? It's something that can nab even experienced people:
# iptables -Ln

Hi All,
Just enabled SIP TCP on a homer capture server, I can see the SIP TCP Sessions on the server with ngrep, just like all the UDP traffic. I have Kamailio listening on TCP ports but its not capturing any TCP traffic.
kamailio.cfg:

Logging reports all SIP UDP traffic to logs fine, but no TCP traffic.

I don't think this is a homer issue because logging invites is prior to any homer processing. I'm thinking this is something simple I'm overlooking, any help is much appreciated.
