[sr-dev] IMS-Call failure.

[Prasannakumar Merugu]

Hello Everyone,

We are having three server

p-server    : 103.211.109.229
i-server    : 103.211.109.230
s-server    : 103.211.109.231
hss-server    : 103.211.109.228 (mysql is installed in this server)

With this configuration, 15 days ago it was working fine and we were able
to make calls.

Recently we installed MySql data base and other application which are not
related to IMS IN  s-server for some other application.
When we tried to make call we are unable to make call. i am unable to
isolate the problem.

The registration process seems to be normal.


Below is wire-shark logs taken at p-server for registration:

My observation is instead of sending the received INVITE packet to
i-server, it is sending to p-server.
Kindly help me to resolve the issue.
If further info is needed, let me know.

Thanking you,
Regards
