In HQ site, I have an IP Phone set with CFA to my mobile number and when there is an incoming call from PSTN to that IP Phone, the Caller ID showed at my mobile number is the main line number of the HQ Site. I knew that PSTN provider had overwritten the outside number (original CLID) since it is not within the specified DID range. Is there a way to alter the calling number to be same as the redirected number in H323 gateway or Callmanager system? In the sample above, I would expect the calling number showed at my mobile is the IP Phone number. Thanks
In the CCM Administration page go to device,
select gateway,find your gateway.
In the gateway configuration page,go to outbound calls configuration setting select :last redirect number" from calling party selection..
hope this helps.
rate if it helps
