Dear sr-users,

I am beginner and apologize for bothering you with such a trivial problem.

I would like to test sip UDP and TCP keepalive pinging. Kamailio and client  are on the same network (192.168.1.44 and 192.168.1.20) that implies not behind NAT. So in kamailio.cfg I have set

My simple kamailio.cfg please you find enclosed.

From logfiles on client's side implies that neither UDP nor OPTIONS pings are sending from kamailio.
If somebody would be so kind to help me I will be very glad.

Thank you in advance

Regards

Petr
