[Asterisk-Users] Voipbuster incoming

[bails]

Hi all, Some friends of mine have an asterisk box which they use for 
outgoing IAX2 via voipbuster.com.

They have been told that they now have an incoming number 0044117*******

The thing is I cant seem to get any debug info on the incoming.

I have tried both sip and IAX trunks but dont see any incoming info.

Anyone have any idea what protocol voipbuster use for incoming calls??

Thanks in advance
