INITIAL

Our SIP2SIM service registers with a VoIP servers, and makes calls via VoIP services. This is done from our call servers, but as we have multiple call servers it is possible for the source IP (the call server being used) to change from time to time. It seems, however, that some VoIP providers are expecting to only get calls from the same IP address as the registration was made. This is odd as calls each way should be independent. However, because of this, we are working on changes over the next few days which would route calls from SIP2SIM to come from the same IP as the registration. The IP in use should remain fairy consistent, but may change from time to time. When this happens we will change calls to come from the same IP as registrations.
