I have users with two lines on their phones. Line 1 is an agent line with no VM, and line 2 is their DID line. I am trying to find a way to have Line 2 selected whenever the messages button on the phone is pressed.
I have found the following service parameter: Always Use Prime Line for Voice Message. If this is true, it will always choose line 1 (which I don't want). If this is false, (which it is), the description says that it will choose a line that has a voicemail.
I have some users reporting that when they press the messages button, it doesn't do anything (because I disabled it for line 1). Other users report that when they press the messages button, it automatically selects line 2 and works as expected, going to Unity. My guess is that those users have voicemail (MWI?) on line 2 of their phone, so it chooses that line for them.
It always works if they select line 2 first, then press the messages button (which is how they were trained to do it).
Is there a way to have it always select line 2 when pressing the messages button?
