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 __________________________________ Yahoo! Mail - PC Magazine Editors' Choice 2005 http://mail.yahoo.com
