ATA dialing out problem

[CoilCord]

I can make calls from all other phones to a certain area code. There are 3 fax machines on 3 ATA's. I cannot make the call from any of the fax machines. All restrictions are the same. I get the "doo doo doo....we're sorry your call cannot be completed as dialed" from the ATA/Fax machines. Any ideas? Thanks in advance

Are you accessing a line pool for the call. you need to put your line pool access code even if you make the prime line the line pool.
