AT&T is adding the DID numbers to our PRI tomorrow or sometime this week. In so doing, does anything need to be configured on the CCM system to make this work? When they do add the DIDs to the PRI will this cause any issues in how things are working now? Basically, if we do need to configure CCM for DID, and we wait to do it later, will the PRI and CCM still function ok until then? I do not want to add these numbers to find out the CCM has to be configured at the same time and we have to issues with outgoing calls again.
Any assistance to my paranoid self will be helpful.
Ok. to fully configure your dial-peers you need to know one key thing...the number of digits your telco will deliever to your gateway..
Ig your telco delivers the last 4 digits of teh DID...4000 to 4299
your dial-peer config will look like this
dial-peer voice 4000 voip
progress_ind setup enable 3
session target ipv4:10.10.10.11 (chnage this to your callmanager address)
If your telco delivers 6 digits i.e 964000 to 964299..and you have 4 digit extension as your extensions, then you will need to configure callmanager such that it will strip off the 96 digits..
This is what you have to do
in CCM under the gateway, scroll down to inbound calls and change the significant digits to 4.
