2600 + 4BRI: can I accept V.120 ISDN calls from GSM network ? Help!

I would like to setup some nokia phones to call a cisco
2611 using a 4 BRI ISDN interface.
According to Cisco web site "feature navigator", I installed
IOS 12.1 enterprise version to have the V.120 feature.
Now the router can receive calls, the router recognizes the call as
a V.120 call, but nothing else happens.

Please help me !
Thank you

Giovanni

I guess I'd add these debugs:

debug modem
debug ppp negotiation
debug v120 packet
debug vtemplate event

Also use some msec timestamps:

conf term
service timestamp debug date msec
