ISDN over IP


#1

Hi,

is it possible to switch data calls through asterisk with the "Dial"
application?

The scenario is as following:

Videterminal (ISDN 2x64k) --> Asterisk_1/BRI —>Eth—>Asterisk_2/BRI —> PSTN
(ISDN 2x64k)–> Videterminal (ISDN 2x64k)

I tried this with normal Dail, but if you come with ISDN/64k (Unrestricted digital information (8)), the outgoing call is an audio call.

Any ideas ?

Thanks,
Darek
