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
