AnswerFor outbound faxing the caller ID of the sender is usually the sender fax number. This is displayed when the call is placed and it rings on the remote side. Once the call is picked up by the remote party, the remote ID of the sender will be transmitted during the negotiation phase. The remote ID is a string (e.g. company name, fax number, etc.) which is used to identify the sender.
GFI FaxMaker allows the administrator to specify the caller ID for each sender and the remote ID for each line.
