CCM 4.2 Call Forwarding to External PSTN Number

Hi Frenz,

I am facing an issue

I have installed call manager 4.X ..

Now if i forward my calls from an ip phone to an external number or mobile . i see the PRI Pilot number on the mobile instead of the DID No.

I dont know y is it taking the Pilot number intead of the DID.

is there any specific configuration to send the DID instead of the Pilot number

Please can some one help with this..

Cheers

AJ

Re: CCM 4.2 Call Forwarding to External PSTN Number

If you are using PRI you may run a debug isdn q931 in the Voice Gateway to see whats the real number CallManager is sending as Caller ID.

Make sure you External Phone Mask Number is configured in IP Phone and enabled the Route Pattern or Route List used for External Calls. In the GW there's an option for preserving Calling number (Originator) is the default.

Sometimes I have seen that Telco overwrites the number when call flow is the following:

Cell Phone| PSTN ---CCM---> CellPhone|PSTN

Telco Switch overwrites that info despite CCM sends the correct originating number.
