Route pattern challenge

[andyjreed]

I've got a small lab setup in a dorm room, with a 1760 serving as my gateway. I've got 2 FXO ports on it.

One of these ports is connected to a MagicJack, which simply requires plain old 10 digit dialing. The other, though, is behind a PBX, so it requires 9+10 digit dialing.

Right now, I have 2 route patterns: 9.@ which points to the MagicJack trunk, and 9.9@ points to the PBX trun...so, from my CUCM phone, if I dial 9+number it routes over the MagicJack, and 9+9+number goes over the PBX line.

This makes call forwarding hard, though. I can only externally forward calls from one incoming trunk at a time..not both.

So I'd like to put these ports in a route group, and simply dial 9+ number, and have CUCM grab whatever lien is free. How can I account for the extra 9 required by the PBX trunk? Is there a way to force it to add the extra 9 depending on which trunk the call is routed over?

Because they require different digits, you must keep the two FXO ports in different route groups. However, you can specify in the route list that when sending calls to the MagicJack, to strip the 9 (pre-dot removal if your pattern in 9.@). Then for the PBX trunk, don't have any digits removed, so it passes the 9. This means you have a single route pattern of 9.@ which points to a route list. The route list points to the two different route groups (with specific digit manipulation for each one).

The only drawback to this is you can't rotate between trunks for each call. It goes to the first one in the route list first and will only use the second FXO port when first is unavailable.
