[SOLVED] Reuse of Speaker output for amplifier

[DWILEY]

I am kulging a SIP audio paging gateway for a VOIP Polycom implementation. The VOIP manufacturers want $100s for SIP audio gateways. A viable solution (when using Polycom phones and their local multicast paging capability) is to use a "spare" polycom phone, clip the audio leads to the internal speaker and connect the leads to a amp that powers legacy analog speakers in our church.

This speaker is a mini speaker driver (2"), not a PC speaker that just does diagnostic beep codes.

The Polycoms have POE power.

Anyone have similar experience with a hack like this? I am interested in noise, balanced vs. unbalanced issues, audio compatibility with amps or have you just been successful.

No help from Polycom as they do not like internal mods to their products.

Ive done this at work with a Allworx VoIP phone, clipped the speaker wires in the phone base and ran 2 wires to a powered loud speaker for paging right next to a large machine.

Thanks. Sounds like you needed a louder ring due to the large machine noise (right?)

I see you mentioned paging not ringing.

Correct, the phone is next to a injection molding machine, the normal internal speaker you could not hear at all if the phone rang or a page was sent to it.
