yeah but more expensive :) If you just want wireless you have options, there are DECT base stations that convert to sip, that lets you have multiple handsets with one base (normally), you have a protocol similar to GSM for authentication of the handsets (ETSI makes many mentions of GSM in the DECT spect) and if you get GAP (the encryption algorithm for link layer encryption) generally you can mix and match handsets and base units. Some dect solutions can be had for as little as $100 including the base unit and 1 handset. If you are looking for more robust wireless solutions, elcotel makes a cpci rackable dect base system which allows multiple base stations for better roaming. And the roaming would be more akin to a mobile phone handoff than wifi - so its faster, easier and generally better. People have connected these elcotel switches to asterisk via the misdn interface. With this switch I have seen 2000 people on one system, 15 or so base stations covering quite a large geography. It does however require more infrastructure than what is generally required for wifi, but then wifi is half duplex and dect isnt, dect has better handoffs than wifi which handoffs are more of a add on later rather than a designed feature. > > I've also tried contacting various vendors such as Polycom, and it > > seems that a lot of them require separate gateway boxes -- the > > handsets aren't speaking SIP directly, or require some other server to > > make it work.

If however you want a simple all in one solution that is just a wifi sip enabled phone, you are probably going to get many of the problems that you have mentioned before. The same is true for the lower end dect systems as well. -- Trixter http://www.0xdecafbad.com Bret McDanel Belfast +44 28 9099 6461 US +1 516 687 5200 http://www.trxtel.com the phone company that pays you! _______________________________________________ --Bandwidth and Colocation Provided by http://www.api-digital.com-- AstriCon 2008 - September 22 - 25 Phoenix, Arizona Register Now: http://www.astricon.net asterisk-biz mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-biz
