How to vix VoIP issues on Virgin SuperHub?

Problems with calls and with registering your VoIP phone online via your SuperHub may occur, especially where there are multiple phones and/or VoIP accounts in use.

Virgin SuperHubs implement SIP ALG which may modify SIP VoIP packets in undesirable ways. Unlike most routers SIP ALG cannot be disabled in your SuperHub's settings.  

For some customers the only reliable solution is to place their SuperHub in modem mode and use a different router instead. 

If you run into problems please try the following steps

• Disable UPnP in your router settings. 
• Set each of your VoIP phones to use non-default local ports. Information about port numbers and the settings location in many phones is available here.
• Test with and without the STUN Server setting enabled in your VoIP phone settings.  

Failing the above the following may provide a solution

• Disable the SuperHub's Firewall options Port Scan Detection and IP Flood Detection. 
• Port forward the Local SIP and RTP (UDP) ports used by your VoIP phone
• Test again with and without STUN enabled in your VoIP phone settings.
