VoIP Telephones and Wiring Configurations
Background: Marc, a Homeowner from Ottawa, ON, Canada
Question: Hi,
I’ve got a VoIP system up and running with a Sipura phone adapter. I’d like to wire the VoIP to my home’s unused “Line 2” so that theoretically, I could plug a “Line 2” phone into any (properly wired) phone jack of the house and access my VoIP line.
I’ve made 2 of my own “crossover” cables (Red to Yellow, Green to Black) and plugged them as follows:
(A is Red-Green side and B is Black-Yellow side)
Cable 1:
A: Sipura
B: Phone jack
Cable 2:
A: Phone
B: Other phone jack

In theory this should work but in practice I get a dead no-dial-tone.

The question is: how do I troubleshoot this?
Any tips?

I feel so close yet so far.

Thanks for the help!
