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

Hi Kamal,

where did you retrieve the config? At some point i made the mistake of
putting "dns_try_naptr=yes" (which should be "no") in the config,
which could lead to the issue your seeing... can you check this?

Kind regards,
Carsten

P.S.: The dispatcher.list file is used as a "Whitelisting" for the
DDOS-Check on the Proxy-CSCF, so the IMS-Core components are not
beeing blocked by the pike-check. On the Serving-CSCF it contains the
PSTN-Gateways.
