Direct Inward Dialling

Hello,

I am about to deploy CUCM 8 at our company and doing some prep for it.

I am trying to configure DID and wish to know some info.

Below is a sample config that i will deploy on my voice router which is an MGCP gateway. Currently I'm outside US and here we have 7 digit phone system. We use a digitial PABX and our we have two different set of DIDs, one starting 211 71XX and  202 45XX.Extensions inside are 1XXX

My PRI is an E1.

Below is what I am planning as config:

dial-peer voice 1 pots

application mgcpapp

incoming called-number  211....

destination-pattern 9T

direct-inward-dial

port 1/0:15

!

dial-peer voice 2 pots

application mgcpapp

incoming called-number  202....

destination-pattern 9T

direct-inward-dial

port 1/0:15

!

dial-peer voice 3 voip

application mgcpapp

destination-pattern 1...

session target ipv4:10.1.2.45

codec g711alaw

Is the above correct, can I include incoming called-number . instead of having the dial-peer voice 2 pots?

After doing this, what do i Configure on CUCM, Do I configure translation pattern or transformation Masks, i a bit confused.

As for CSS the gateway must use the same CSS as the phones?

Thanks to help.

I'd strongly recommend you to review MGCP documentation about how to configure this.

How to Configure MGCP with Digital PRI and Cisco  CallManager

Inbound CSS from GW is exactly the same as what you configure in any device, it determines what devices you can reach. Just configure it accordingly to reach whatever internal devices you will reach thru that GW.

Hello

Thanks. I have been through some documentation, is the config ok?

Do you use translation pattern on cucm for this?
