I have 2 extensions on my system, (Ext 14 and ext 15) that are using ATT MLS-12D phones.
If a call comes in you can answer it with no issue on those extensions, but if a call comes in and you answer it on another extension and place it on hold and try to
answer the call on one of those extensions, you can not get the call to come off hold when you press the line button. (We have 4 outside lines) Also the intercom, and speaker buttons do not activate as well. I checked to see if those extensions were restricted on calling out and they are not in the set up, I also unhooked the phones and placed them on extension 10 my main phone and they worked normal allowed me to answer hold calls and the other features kicked in, when i placed them back on the extensions it stopped again.
Any ideas on what this could be?
