We run callmanager 3.2(1) with a Catalyst E1-Blade for PSTN-Breakout via a Nortel Meridian PBX. With incoming calls from PSTN we miss the leading zero(s) from the PBX that are necessary to use the "missed calls" directory on the 7960 IP Phone without editing.
Is there any way to prepend leading zeros on incoming calls from PSTN within callmanger? How can we distinguish between incoming PSTN calls and incoming PBX crossover calls from other subsidiaries?
With callmanger 3.2 this is very easy. In callmanager translation pattern config you can now prefix outgoing calling digits. Set up the calling search space on the gateway so that it can only call a translation pattern that matches your did's. Then under calling party transformations for prefix outgoing digits add the the 0 there. Then the calling search space on the translation pattern should be able to call the ip phones.
The problem you have is the calls coming in from the PBX which are none PSTN. If you just prepend the 0 as suggested by others then every time a user on the PBX calls then you get their CLI with a leading 0.
What I suggest you do is configure the outgoing CLI on the PBX to prepend calls with the std code and any leading digits before the extension number but again without the leading 0. This way all calls accross the link (PSTN or PBX) appear in the same format and missed calls will work. you then configure a route pattern to recognise the std code and preceeding digits as being routed over the link to the PBX and to strip them back off again.
I know it seems a bit long winded but you have to realise that when you put 2 PBXs together you can't expect to do all the configuration work on 1 end only.
Just as an additional helper I would suggest putting 90 infront of the incoming CLI that way you don't need to edit dial to insert the 9.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
