ISDN2e (BRI) to SIP

[Turkey Machine]

Hi guys and girls, I am in need of some advice (and possibly kit) which will solve the following scenario.

A customer has an ISDN2e system, aka BRI, with a main number and 10 DDIs. They only wanted the one DDI because it's particularly memorable.

What they would like to do is route the incoming calls on that DDI to their SIP account with the minimum amount of hassle, bearing in mind they're in a 12 month contract with *cough* BT.

Is there a box of tricks which can do such a thing, i.e. automatically route the incoming calls to a SIP account? The only boxes I've seen allow calls over VoIP with ISDN phones.

Cheers in advance.

The only possible solution that comes to mind is an old PC running Asterisk with one of The digium b410p cards installed. The guys at VoipSupply should be able to help you out though and they know their stuff. I got my voip hardware from them, fast delivery too.
