[Asterisk-Users] Recomendations for an ISDN-PBX to use with asterisk

[Oliver Brandt]

Hi,

I'm planning to buy a new ISDN-PBX (I hope this is the right term for an
ISDN phone system). I would also like to connect it to asterisk. As far
as I know there is no ISDN card where I can connect an ISDN-Phone to
directly working together with asterisk (please correct me if I'm
wrong). So what I was thinking of doing was to get a regular ISDN
PBX and add a second internal S0 bus which I'd connect to asterisk using
chan_capi. Now to place a call through asterisk I'd first have to dial
into asteriks and then have asterisk give me a dialtone and recognice
dtmf. Is there any way to just prefix the phonnumber with lets say a 9
and then have the PBX transmit the rest of the number to asteriks so
that I would not have to go through two dialtones? Any suggestions on
what PBX to use if this is possible? It's supposed to be for a private
home so I should not be some really expensive professional one...

Thank you very much!
Regards
