[Asterisk-Users] Asterisk switching ISDN data calls?

[Jan Baumann]

Hi,

I wonder if it is possible to switch ISDN data calls with asterisk.

What I want to do is have a Digium TE400P in an asterisk server, one E1 
interface connected to a PRI ISDN line and one in PRI network-side mode 
connected to a Cisco PPP dialin router as an "extension" capable of 
handling 30 simultanious calls.

Incoming data and voice calls (depending on the caller having an ISDN 
card or a modem) for a specified extension should be routed to the Cisco 
for termination.

Another application could be connecting a legacy PBX via PRI trunk to 
simulate the telco switch and VoIP enable it this way. Will my data PBX 
extensions (PCs with ISDN PCI cards) still be able to dial out through 
asterisk to place data calls to other PCs?

Has anybody tried this (maybe Mr. Junghanns with the 4xBRI card) ?
I would very much appreciate reading your experiences.

Thank you all,

Jan Baumann
