[Asterisk-Users] A few questions - isdn call routing

[clive18 at webmail.co.za]

Hi

There is a device called a "parlay" made by a crowd called
voxtream which will route the ISDN calls based on the DID
and/or the callerid, before the  call is answered.

It would be nice if this feature could be done in Asterisk
as well, but at this point in time, it first answers the
call.

regards
Clive
