Hi ,

Yes , I have tried uncommenting that part . It is actually checking for hostname (sip.example.com:5060) in my scscf node. I am not sure why it is looking for sip.example.com instead of scscf.sip.example.com:4080

I have added one more alias in my scscf.cfg file .Now Domain not served issue has gone.

After that I am facing 483 Too Many Hops Error.

I have added scscf debug logs.

I am facing host is not me error . Here 10.45.6.73 -> scscf and 10.45.6.75 -> UE (bob user)

I am not sure what alias it is asking for . Kindly help.

Hi, 

Most likely this is because of the change. Revert back the changes (uncomment the section I told you), turn on debug in scscf.cfg, restart all nodes and test once again. Then have a look on the scscf logs. 

Regards,

Pavel Siderov
