The rest of the phones in the building are digital phones with multiple buttons. (Line1, Line2, Intercom, etc.) We have 5 lines set up as public, so you just hit the button of the line you want to use, and dial out from there.
The new conference phone is an analog phone hooked up to an ATA2. This phone doesn't have the programmable buttons, and I'm having trouble figuring out how to get it to dial out. The external code is set as 9, but pressing 9 + xxx xxxx doesn't work.
I tried dialing out using 9 on one of the digital phones, and that doesn't work either. Will adding lines to a line pool affect the existing phones? I still want the lines to be public. Is there a different way to get this conference phone to dial out external?
