Configuring CM for long-distance access codes

[NarK]

Hello all,

I am testing out Cisco Call Manager in a small test environment in our company. I'm having a problem with configuring the CM for long-distance access codes. I would appreciate any help in this regard.

I've managed to get the local external calls working thru the CM. The users have to dial a 9, followed by the 7-digit local number, and this works fine with a route pattern of
9[2-9]XXXXXX.

In our non-IP phone setup, for long-distance calls, the users dial a 8. They then receive a tone and have to dial their 9 digit access code, followed by the 10-digit long distance number.

Any ideas on what route pattern to use to achieve this with IP phones and Cisco CM 3.1?

I guess what should happen is that the moment the user dials a 8 on the IP phone, the 8 must be sent by the CM to the switch at the other end. The tone from the switch must then be relayed back to the IP phone. And then the access-code + number must be sent to the switch. Is this correct? In either case, I'd appreciate any help on this issue.

Thanks,
NarK
