Hi,

I am trying to configure OpenSER such that it pings its NATed clients with SIP OPTIONS packets instead of the default dummy UDP pings. But, no matter what I do, OpenSER always sends the usual UDP pings.

My openser.cfg contains the following lines –

modparam("usrloc", "nat_bflag", 3)

modparam("nathelper","natping_interval", 60)

modparam("nathelper","rtpproxy_disable", 1)

modparam("nathelper", "sipping_bflag", 3)

modparam("nathelper", "sipping_from", "sip:openser @mydomain.net ")

Before save(“location”) in the route blocks I have –

Fix_nated_contact()

And on reply route to the main route block I have –

Fix_nated_sdp(“3”).

NAT is working perfectly fine otherwise, I just need to get OpenSER to ping with SIP OPTIONS instead of dummy UDP packets.

Can you please help me achieve that.

Regards,

Amit.
