Behaviour
This feature checks incoming SMS Register messages for the presence of the +g.3gpp.smsip parameter in the contact headers of the message. If the parameter is present, the 'isSmsip' session state field is set to true. In all other cases the field defaults to false.
If is an SMS over IP session, this feature also extracts a valid phone number from the IMPUs of the incoming REGISTER request and sets the MSISDN session state field.
