[SR-Users] RTPProxy with kamailio : How to get calls count?

[Alex Balashov]

I'd be curious to know if your performance might actually be higher, owing to improved CPUs since the study was done, hyperthreading, more frames per NIC interrupt, etc.

One more thing, I found these errors in syslog:

Sep 13 18:38:18 perftest kamailio[5268]: ERROR: <core>
[parser/sdp/sdp.c:211]: Invalid payload location
Sep 13 18:38:18 perftest kamailio[5268]: ERROR: <core>
[parser/sdp/sdp.c:227]: Invalid payload location
Sep 13 18:38:18 perftest kamailio[5270]: ERROR: <core>
[parser/sdp/sdp.c:227]: Invalid payload location

This is possibly something related to my sipp scenario, this is the
INVITE sent from sipp

Do you see something that could cause this error ? Otherwise the call
is initiated ok, but I really dont understand what is so strange to
kamailio in this INVITE.
