Joseph I do this with multiple DIDs on a FreeTDM ISDN trunk. In the public context dialplan I have an extension for each DID (and a catch all ^.*$ at the end because I like to install a known catch point in case the provider [BT in UK] goes mad): <extension name="public_abc"> <condition field="destination_number" expression="^987654$"> : : <action application="set" data="effective_caller_id_name=ABC:0${caller_id_number}"/> <action application="set" data="effective_caller_id_number=0${caller_id_number}"/> The provider drops the leading 0 from the caller ID, so I add that back in, and for the name prefix with ABC to represent the incoming DID. Also, my provider only sends the last 6 digits as the called number; your mileage may vary... John On 20/02/12 07:26, Victor wrote:

One way is to add a prefix to the incoming callerid name. Ex: DID1-DOE,JOHN

I have two offices that each had their own single external did and have now combined locations so they want both dids registered on one server.

However they want to discern from which did an inbound call originates on their Aastra desk phones.

Anyway to accomplish this?

Thanks! jlc
