Try adding the following to your handset config in sip.conf. This forces the 
SIP device to get it's ring tones from Asterisk. Worked for us in v1.0.9 with 
Polycom handsets.

Be careful when ordering an ISDN2e line from BT. By default they come 
configured as Point-to-Multipoint with any additional numbers as MSNs. Most 
PBXs are better with ISDN2e Point-to-Point with DDIs, but BT then sting you for 
a £100 DDI planning fee in addition to the ISDN2e installation. One thing to 
consider is that DDIs are allocated in contiguous blocks of 10 numbers e.g. 
0115 7889100 - 7889109. MSNs however are purposely allocated by BT randomly in 
what ever quantity you require. Officially you cannot have contiguous MSNs 
which aren't so good for PBX use.

If you want inbound CLI display (CLIP) and/or the ability to specify the 
outbound number you are presenting as a CLI (CLOP/COLP depending on who you are 
talking to) this needs to be specified as well. By default you get neither but 
both are non-charegable upgrades (in our limited experience).
