Hello,
After some tests, I'm still having some strange results.
When calling from ws client to grandstream, I get the below output to
/var/log/messages.
In a sip trace after 488 there are only INVITEs from kamailio server to
grandstream but no responses come back to kamailio server.
I haven't changed any other configurations, kamailio or otherwise. I run
the rtpengine like this:
/usr/sbin/rtpengine --table=0 --ip=1.1.1.1
--listen-udp=127.0.0.1:7722--listen-ng=
127.0.0.1:7723 --tos=184 --pidfile=/var/run/rtpengine.pid
(where 1.1.1.1 is my kamailio server ip)
How do I work out the problem from here? Please let me know if you need any
further info or logs and I'll dig those out.
cheers,
Olli
