I bought 2 spare phones from you to place in common areas in the office so anyone can pick-up calls to a shared line group. I have an Office plan with 2 digital lines. Can I use one of those two digital lines for the shared line group?
Yes, you can share 1 of your lines b/w 3 phones, but will only be able to take 1 phone call at a time. There will not be any call waiting. With Shared Lines, you can share up to 8 phone with 1 line... but again only 1 call at a time.
The Admin will need to create a Share Lines Group under Phones Systems > Groups/Other > Add Group and then select Existing Phone. If the DL Line you want to use is already assigned to a hardphone, then support will need to unassign the DL so that it can be assigned to the shared line group.
