Hello, I was following http://code.google.com/p/homer/wiki/HOWTO#Capture_Agent to have "Homer Sip capture" capturing an displaying a SIP Packets from freeswitch. This worked quite well on a Debian based system. But now we migrated it to Centos 6 and it does not work anymore, although we used the identical kamailio source code base. I think the underlying xml parser libs somehow work differently on Centos. What is puzzling me is the following Apr 4 10:33:12 homer2centos /usr/local/sbin/kamailio[20698]: ERROR: <core> [parser/msg_parser.c:705]: parse_msg(): ERROR: parse_msg: message=<#001#020#002#021#023a#023aaaaaaaSIP/2.0 480 Temporarily You can see that in front of the SIP message coming from freeswitch there are some additional chars "#001#020#002#021#023a#023aaaaaaa". And by wiresharking the SIP packages, Freeswitch in fact preceedes the SIP message it sends to homer with these additional bytes. Using a Debian based Kamailio this does not cause problems on the Kamailio/Homer side, buit on Centos it does. So my question is: Is this the right behaviour of Freeswitch when forking the SIP message to the capture server? In https://groups.google.com/forum/#!topic/homer-discuss/KhBF0Dy44SU I found the following
The problem was found: freeswitch duplicate all packets on SIP port including empty "ping" messages. with mobile regards, Alexandr
Although I do not really understand the part "including empty ping messages": Is there a way to suppress these ping messages?
