How do i program my incoming line to ring on all my phones?

Question

my incoming calls on ring on the main phone.

Answer 1

its a real cool calling feature called simultaneous ring!!

I use it and have it on all my phones....cell....home....work...condo   up to 5 different phones. This feature you get from your phone-provider...so call them!

Answer 2

It depends on your service provider.

I use InPhonex VoIP service.  They have a feature called Call Hunt and Call Forward.

With Call Hunt, I can set my account to Sequentially, or Simultaneously ring any list of phone numbers I specify from my admin dashboard.
