I've seen some numbers on total analog modems sold as high as 86M units in 2001 (which sounds high to me), to somewhere around 1.5-2M units sold in 2003, but I haven't seen any breakout on voice modems anywhere. Any thoughts/info would be greatly appreciated! Like I mentioned, this is for a new voicemail application I am working on, which is really applicable only to PC internal modems (2 RJ11 ports; not applicable to laptops), and focused primarily at developing country markets (so any regional data/trends would be greatly appreciated as well). Thanks in advance! -Tim

Not all 'voice' modems are V.253 compliant, however. The manner in which modems with 2 rj-11 jacks work also varies: some disconnect the 'phone' jack when the modem is off-hook; some do not. Aloha! Richard.

I came up with another question since I posted this today, and would be curious for your thoughts/knowledge as well: of the voice modems sold, how many are VTR capable (full duplex voice)? (most, some, few, etc?) -Maybe this is a subset of the v.253 modems? Thanks again. -Tim Tim Driscoll
