[VoIP] Another WE question

[Jayson Smith]

Hi,
Last Friday, Lucky225 told me to get the WE 3500 if I wanted the ABCD tones.
I couldn't find one of those on eBay. Is the 3500 just like the 2500, except
that it has four extra buttons? I'd imagine the ABCD keys being to the right
of the 369# keys, simply because that's the column the silver box makes
switchable. Is this right? Are the ABCD keys used for much these days? I
know they used to be used in Autovon. Heh, anybody ever thought of coding
Autovon call priorities in Asterisk?
Jayson.
