Solved: Re: Call Forward All

Peter Valdes · ‎11-25-2010

Hi,

Our Telco requires us to send them the allocated DID range when making a successful outgoing calls.

For example, Telco has given us DID of 8888 1000 to 1100 (so 100 DID range). We send them a calling number of 8888 1000 ID. If the ID does not match the range they give us, they will not route the call out. For example, calling number is 8888 1200 (not part of the DID range).

Our problem is when we forward a phone to any numbder external to us, the calling number is beeing sent to the telco and they see it as a mismatch of our DID range.

Is there a way we can override the calling number by setting up a pilot number (8888 1099) for calls the are forwarded outside?

The debug below is what I get on a failed call. Calling from an external number to 88881000 which has forward all calls to 0061292315555

I can suggest two methods.

1. You could change the gateway setting in the CallManager to send last redirect number as the calling number, instead of the default "Originator". Change the "Calling Party Selection" setting from default "Originator" to "Last Redirect Number (External)". This assumes that your DNs are configured with external phone number mask (8888XXXX), or something similar.

2. If you are using SIP or H.323 protocol to control gateway, you could configure translation on the gateway itself, like this:

voice translation-rule 1

rule 1 /^0.*/ /88881099/

!

voice translation-profile CALLING

translate calling 1

!

voice-port D_CHANNEL_INTERFACE

translation-profile outgoing CALLING

This will translate any outbound call CLID that starts with "0" to 88881099. If it starts with 8888xxxx, it won't be translated.
