Outgoing DDI

[pcromwell]

We have a PBX -> QSIG->2900->CUCM8->ISDN2900GATEWAY.

I would like to display DDI number when making calls over the PSTN  (this is from the PBX handsets and Ip Phones)as opposed to the main number. I know you can do it on the phones. but I want to do it for all our handsets. Is their anywhere that I can configure it?  I am using MGCP gateway.

I appreciate that the PBX phones needs to be configured to send full ddi calling number first. but is it possible?

You can configure a mask in the route pattern/route list like this:

1234567XXXX and the final 4 digits will be replaced by the DN from the phone.

PBX Phone (Ext. 3210) --- GW --- CUCM --- PSTN GW ---Calling Number:617 888 3210

Is that what you want?.

If yes...

You could do it 2 ways

1) Send full DDI from PBX to CUCM

2) Send Extension from PBX to CUCM, but do Digit manipulation before the call actually goes to the PSTN Gw.!

Yes The PBX will send 4 digits, If I apply the mask to the route list, that will prepend before reaching the gateway.

many thanks
