[OpenSIPS-Users] Manipulating Contact header in locally generated 200 OK for a REGISTER

[Bogdan-Andrei Iancu]

Hello,

The SIP RFC3261 says that only the registered URI contact (along with 
the URI params) are to be stored by the registrar server. The header 
params are not to be stored.
So, should I understand the that GSMA specs may conflict with the SIP 
specs ???

BTW, do you have an example of such a Contact hdr ?
