VoIP Ports

[TomKelly]

Can anyone advise what ports need to be opened for BT VoIP?

I'm 100% of calls dropped, atleast 20-25seconds into the conversation, so doing what I can to clear this up.

Cheers,

Tom

BBV Incoming Port Ranges (all UDP) - 32000 to 36000 & 2727 & 5060 & 49152 to 49193

Do these use the "SIP-based Internet telephony" Application Type?

If it's the Business Hub you're using, SIP-ALG is enabled by default.
