[cisco-voip] External Call Forwarding

[Fuermann, Jason]

We have ATT here and they will only let us use our DID’s for outbound calling. However, when I receive a forwarded call, it shows up as the original caller and says call forwarding (at least on my cell phone). I do have Redirecting number IE Delivery checked under PRI protocol type specific information. Might want to check there first.

Does this have to be supported by the PSTN provider? We have asked them to remove the filter so we can put any number on the outbound call. Is this enough?

Look at the calling party selection setting on your outbound
gateway.  It's probably set to something like Originator currently,
where you want something like First (or Last) Redirecting party.

Hi All,

I have a question about call fordwarding.

Scenario is that when an ip phone is forwarded to an external number
and another external number calls that ip phone the call is forwarded
to the external number. When the forwarded call reaches our outbound
gateway the calling number is the external number that started the
call and the called number is the external number that which is
configured for the CFA. Our carrier does not let us use any other
number then that which is in the DID range so they change the calling
number to the pilot number of the DID range.

Say the DID range is 123456XX (100 Numbers). Extension 5602 is CFA to
0456785856 (external mobile). External number 4555598598 calls
12345602 and it forwards to 0456785856. Currently the calling number
that shows up on the mobile phone 0456785856 is12345600 (pilot of
DID). I wouldl like the number to be 12345602. Debugging on the
gateway shows the calling number as 4555598598 and the called number
as 0456785856, our carrier does not recognise the calling number as
part of the DID range so changes it to the pilot point.

Is there anyway to configure the calling number to be the number of
the phone that forwarded the call instead of the original external
number?

cheers,

Daniel
