I want to be sure I'm understanding all the relevant requirements before investing in the necessary gear and seeking out the appropriate provider.
If I have an existing traditional (not IP) multi-line phone, can I run multiple phone lines to it from an Obi 504 (or similar), port my existing landlines to a VOIP service such as Anveo or Google Voice, then continue to use those lines concurrently (three phone lines in simultaneous use)?
By the way, if you are curious, my reason for doing this is that this particular phone connects wirelessly to several desk phones, any of which can be used with the three landlines currently connected to the wired base phone.
Thanks in advance for any guidance you can offer on this set-up.
