[SR-Users] Strange, can you help me to understand?

Mon Mar 3 14:11:26 CET 2014

You have to provide the traffic taken on kamailio server, with both 
sides of the call. Now it looks like with one side, not saying which one 
is the proxy.

As I blind guess, in case there are more proxies involved, I expect one 
of the proxy in the chain not fixing properly for nat traversal, 
replacing the contact with the ip of the other proxy, by using 
fix_nated_contact(). In kamailio we recommend now the way of using 
contact alias parameter (set_contact_alias() along with 
handle_ruri_alias() -- see latest default config).

Cheers,
Daniel
