<div dir="ltr">Hi,<div><br></div><div>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 :)</div>

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