I just opened up a phone with a colleague who has electronics experience. You can easily enough unplug the builtin speaker and plug in an amplified speaker if it has 8ohm input. Otherwise a simple balanced transformer will do.

Something to think about.

I gave up on trying to use the phones for paging. We still have one school left that was done that way, and we are in the process of undoing it. The only thing that has any hope of competing with the ambient noise in a room full of students is an actual, honest-to-goodness paging speaker. You think a Grade One classroom is bad -- try junior high.

We found IP speakers still too expensive to implement so we just use an analog paging system hanging off an FXO port. Bogen PCM2000 in most cases.

That's all good in all but we are trying to help increase the volume of paging in hopes of it being louder then 30 1st grade kids.    I need a way of micing the internal speaker out.

any other ideas?  I know I could put an IP speaker in every room but kind of defeats the purpose of the phone in the class room cost savings ;-o

I think that feature is being deprecated. Too bad really. I would really like to have a phone with an input/output jack.

In the meantime, you can use something like this:

on the 7970's they have external mic and speaker jacks.

in CM 4.1 I enabled them throught user pref / audio pref and they worked.  I'm trying another 7970 in CM 6.1 and the same audio pref but he speaker is grayed out with internal.  Can you no longer use the external jacks or is it a load issue?  I'm running 8.4.1sr2s

Thanks

Scott
