[SR-Users] Kamailio 4.16 - IMS Registration Failure

Hi Carsten,
There is not entry for dns_try_naptr in any of my config file.

Regarding dispatch list, I do not have PSTN gateways.., what shall I put in
dispatcher.list file for SCSCF.


I tried to comment loading of dispatcher module, but endup getting error in
kamailio.cfg (looks some functions are referred from dispatcher module in
kamailio.cfg).


Totally clueless.., Not sure how to proceed.

many thanks
kamal
