[cisco-voip] ISDN data calls over H.323?

[Vincent De Keyzer]

Interesting, thanks.

The drawback of this system is, however, that you need to have a special
dial-peer with codec "clear-channel". What I would like is a single
dial-peer where the codec selection is based on the bearer-cap of the ISDN
call: if bearer-cap is unrestricted, use "clear-channel" codec; if
bearer-cap is speech or audio, use G.711.

Is that possible?

Vincent
