Hi!

Yes - no problem.

Usually the fax is analog 14,4k connection. The channelbank does the 
digitizing to ulaw and the other end coverts it back to analogue. Afaik 
no matter if its european or american ISDN. No problems experienced by now.

That depends on your channel bank. Rhino channel banks for example are 
specially designed for asterisk. But most T1 channel banks should do.

Don't kow that ;-)
