We will be doing some work on the VFX network by adding support and moving devices to UDP / TCP port 5060 which by default is the Standard SIP port, this is in response to an issue we have seen with the Dynalink Modems not fully supporting other UDP ranges for SIP which we are currently using, at this stage we don't know if they will address the issue so we are now having to make allowances for this since they are a major player in the NZ router market.

For most users any changes will not be seen, but users that the are fire walling based on ports please add a range of UDP / TCP 5060 to 5065.
