[Asterisk-Users] Sipura SPA-1001 question

[burke at tailorhosting.com]

Asterisk-Users,

Is anyone out there using the SPA-1001 for integrating existing analog
phones into a VoIP setup? My question has to do with the MWI. From the
datasheet it says that it provides MWI Tones, and then that it provides
Visual MWL "via FSK". What does "via FSK" mean? My exsting phone has an
answering machine built in and I am debating using Asterisk as the
Voicemail, or just the exsting answering machine. Any comments or insight
into the SPA-1001 would be appreciated.

Thanks,
Ryan
