Some providers change the Contact header when replying the register.
The provider says 200 OK for register but I got this: ERROR: uac [uac_reg.c:876]: uac_reg_tm_callback(): got sip response 200 while registering
I think the problem is at https://github.com/kamailio/kamailio/blob/master/modules/uac/uac_reg.c#L744
In my case, the provider change the username part of Contact in register request: Contact: sip:DID_NUMBER@IP_ADDRESS:5060 in reply: Contact: sip:SiENC*DID_NUMBER**IP_ADDRESS*5060*@IP_ADDRESS
So if username is different, I will never get ri->flags |= UAC_REG_ONLINE;
The change done by registrar server to the Contact URI is not compliant -- the address has to stay what the UA has set. Otherwise a lot of multi-line SIP phones won't work.
The user part of the Contact in the REGISTER generated by uac module is used to match the local user details. If the user part is changed then it is not going to be a match when a call comes in with the modified Contact address in the R-URI.
