[Asterisk-Users] Asterisk - PRI - Cisco

[KaveH Aasaraai]

Hi,

I got a situation with not having enough knowledge of
PRI and Cisco things.

I wanna make a plan as follows:

An Asterisk having a digium PRI card, and a Cisco 3660
also having a PRI card are available.

We have two PRI lines which are connected via one
basic phone number through our phone provider, so we
have logically 2*32 slots concatenated, acceissible by
a single 4 digit phone number - although caller must
dial 8 numbers, but only first 4 numbers matter.

I want to make outgoing calls through Asterisk via PRI
line, and I'm currently doing this in an easy way by
pluggin one PRI line into the digium card in the
Asterisk machine.

I want to handle incoming calls by Cisco 3660 via PRI
line to give a dial-up service to users, which is
being serviced too.

The thing which is making this hard is to have
incoming calls in two PRI lines separated by dialed
number, and route half of them to asterisk. That
means, I wanna give two services at the same time, one
dial-up service and one in-company VoIP service via
PRI.

The problem is how to route calls from Cisco 3660 to
asterisk, because I can't just plug the second PRI
line into asterisk's PRI card, because my phone
provider simply routes the calls to my number to my
lines as described above. So, the only thing which
distinguishes the caller is the number he/she's
dialled. The first four numbers are dedicated to my
lines, but he/she dials 8 numbers, so I would have 4
numbers to decide on.

I would appreciate any help anyone could give, cuz
it's really needed and my phone provider won't change
the way it's routing my calls!

Thank you in advance,

Kaveh
