Are BT blocking VoIP?

by Suw on October 28, 2004

I've been working for the last few months with a client with a VoIP product and, out of general enthusiasm for it, I offered to help test it here in the UK using our BT Broadband ADSL service. Our broadband is a consumer, home service, and usually works just fine – it's worked with Skype and various other proprietary VoIP products with no problem.
Now, BT's FAQ says this:

Question
Do Voice over IP (VoIP) services work over BT Broadband?
Answer
BT Broadband is compatible with VoIP services, provided you are running a suitable application on your computer.

Yet we seem to have discovered that BT appears to be explicitly blocking port 5060. As Joi points out, if it is true that BT are deliberately blocking VoIP packets, then it's astonishingly bad behaviour.

Priorities, priorities

Got up to London last night, walked through Acton in the pissing rain but felt happy nonetheless. Back in the land of the living.
Almost the first thing I did was look at Svet's computer for ethernet, and was delighted to find it – no need to install a network card then. Was slightly less delighted to discover that just plugging my PowerBook in wasn't quite enough, damnit. Fixed it this morning with Simon's help, and now I'm ready to rock and roll. Or, rather, pop out for lunch.
So, I'm here. I'm online. I'm happy. I bet the next four weeks are the fastest of the year. Hm. Wonder if Svet wants a lodger…
