All possibilities should be explained in the user manual of the "phone modem". That's a modem from the Internet provider? Then they should have a manual available on their site.
Maybe it just isn't possible with their modem.
I am an attorney. It is just me and my assistant in the office. I have a two-line phone system installed but the internet company isn't very knowledgable about the inner workings of their own system. Here is what I would like to do.
I have two lines: line 1 is the main office number, and a second line that rings if line 1 is busy.
Both phones are connected to the phone modem, one is connected to the Line1 & 2 port, and I believe the other is connected to the Line 2 port. Both ring when someone calls line 1.
I am trying to figure out how to make only the assistant's phone ring when she is here, and then she can change it so that it either rings both, or sequentially rings hers and then my phone when she is out so I can pick up calls at that point.
I have designated the main line as her line in the software for the internet/phone provider (Comcast) but due to them both being hooked up to the modem, and the fact that they both ring when a call comes in, I don't see any other way of designating that particular phone to be only Line 1.
Is there a way to make her phone only ring for Line 1 calls. And then if she is out, make Line 1 ring (1) either both phones so I can answer, or (2) ring the main line, then the second line (That is called Sequential ringing in the internet provider's website management that I am playing with which seems like the option I have. But don't know how to keep my phone from ringing when she is here to intercept the calls coming in from the main line. I tried plugging it in to a Line 2 port on the modem and it still rang when the main line was called. )
As I said, I have Comcast Business Phone system and have a Vtech Dect 6.0 phone in my office and another brand 2-line phone in hers. We came from Vonage which handled all of that pretty well. But it just made more sense financially to get phones through our internet provider when we relocated. They said they could provide all the abilities that Vonage could but we are still struggling with this last ability to be able to have only one phone ring during the hours the assistant is here.
Any help/guidance would be greatly appreciated.
