Hi,
you find a working example actually in the examples/pcscf/ Folder of Kamailio. Since we don't have a full compatible usrloc-API for IMS (yet), i used nat_traversal as replacement for nathelper; as it's not relying on the usrloc-database.
In the config we have: # ----- nat_traversal params ----- # If another keepalive is wanted, this is the place modparam("nat_traversal", "keepalive_interval", 10) # If another method than NOTIFY is wanted: modparam("nat_traversal", "keepalive_method", "OPTIONS") # From? modparam("nat_traversal", "keepalive_from", "sip:keepalive@HOSTNAME") # Where we store information about keep-alives: modparam("nat_traversal", "keepalive_state_file", "/var/run/kamailio/keepalive_state")
With these parameters, we just call "nat_keepalive();" before forwarding the request to the IMS-Core. This works for us... (with latest 4.0 or trunk versions, i haven't tried it before).
Kind regards, Carsten

Hello,
not using this module, however, after you start, can you see a dedicated timer module 'NT' if you do kamctl ps?
Cheers, Daniel

Hi all,
Currently evaluating the nat_traversal module in some tests, and trying to configure keepalives for registers. We currently use nathelper, but due to the distributed nature of our setup, nat_traversal seems more appropriate for the keepalive functionality (nathelper is sending keepalives from every node).
I am calling nat_keepalive() before save(), but no keepalives are being sent. The documentation suggests that is all there is to it, but maybe I'm missing something. There are no errors in the log that I can see.
Any ideas?
Many thanks,
Charles
