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

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,
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

Hi,
Many thanks for your replies. Turns out we were calling t_newtran()
elsewhere in the config before handling the register, and I guess the
callback was being attached to the wrong transaction. Now it's removed, all
is working fine :)
Best,
Charles
