[SR-Users] Kamailio 4.16 - IMS Registration Failure

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.
