NTL dialing cardiff and other sip numbers
 

I have several VOIP/SIP telephone numbers some of which work fine when dialing from NTL but others have never worked whilst other did work but seem to have stopped recently.

When I dial my cardiff VOIP number which starts with 02920 0, as soon as ive dialed the last 0 i just get what seems like an error code.

I've tried several different VOIP providers from VoxHum, SipGate and even Vonage all have very similar cardiff numbers and all have the same problem. Vonage tells me its a routing problem with NTL?

Does anyone else using an NTL experience the same problem?

NTL users, it you want to you can try this number
029 20026599
which is their voicemail access number.

NTL decided to send an enginner out (dunno why they couldnt fix it on the phone) where the enginner agreed with me. They had no support for routing calls to numbers starting with 0 in the Cardiff Area.


The problem appears to be resolved.
