The IP501 has 3. I know it's a considerably better handset than say the PA168 or AR1688-based handsets, but then they are $45 and the 501 is £125. I'd also be more sold on it if it had half the features of the GXP2000 (which is only a little over half the price). _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- AstriCon 2008 - September 22 - 25 Phoenix, Arizona Register Now: http://www.astricon.net asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
