[sr-dev] Problem with Registration on pcscf

[Carsten Bock]

Hi Paul,

since probably i'm the guilty one, i would check. In order to quickly
reproduce that issue, some quick questions:
- you are using GIT master? I've made some changes in GIT master
(compared to 4.1) in terms of detecting, if a user is registered...

Can you send me the SIPP-Scripts?
I will then check next week for this topic.

Thanks for testing,
Carsten
