Yealink doesn't make a paging adapter, told that Valcom and Bogen do.

In the old Sanyo days we would cut the speaker leads off the cheapest phone and use that as the page input.

Will need an input device for overhead paging soon, just looking for what anyone else uses.

Thanks, Bracha

Is this a hosted system?
I have used this with good results:

Made my own voltage divider network to convert from speaker level to line level and into a paging amp.

Thanks for the tip on the Snom PA1. Certainly less expensive than other options.

Would you have a diagram/parts list for your voltage divider network?

Thanks, Bracha

I can draw something up. It's just 2 resistors wired together, I used a small euro terminal block to make it easier to work with.
