Yes they do. For DDI ranges you'll need to ask BT for a "System Access" 
installation (sometimes known as "Point-to-Point") and configure the 
Junghanns appropriately.

I'm probably just an old fogey with a programming background, but I find 
straight Asterisk *so* much easier to configure than a at h.

When you say "ringtones", do you mean "sounds like a UK phone when it 
rings", or "sounds like a UK phone when we ring someone else" ?

If it's the latter, you need "early b3 connects" so that you hear the 
tones generated by BT rather than the ones the Grandstream generates. 
With CAPI (which I tend to use), you add the "b" option in the dial 
string. I presume bristuff does something similar.


exten => _0.,3,Dial(CAPI/g1/${EXTEN}/b) ; always ask for early B3
