I am setting up an ELX3000 with 50 users and a T1. Each of these users wants a fax line of their own. I have plenty of DID's from the T1 provider (block of 200). My question is should I set them up with a different number for their fax than their voice or can I use the same number for their voice and fax and have the elastix autodetect. I have followed the instructions for setting up a fax and it works but it only is for a single pstn line. Just wondering what is the best option. and the easiest to setup. Also the faxing will be used primarily for inbound faxing only.
