Number of simultaneous lines? Budget? Number of minutes monthly? Is your greatest expense going to be the hardware, or the phone charges? What you're planning to do with it? I've done a lot of work with SIP-based MeetMe conferences, and let me tell you that DAHDI-based MeetMe seems to 'just work', compared to all the tuning we put in to get SIP-based, dahdi_dummy -timed MeetMe working and not sounding bad. My company priced out several options and determined that our best pricing was to minimize the cost of calls by purchasing dedicated TDM hardware and have telco terminate locally. We run SIP in some cases inside our VoIP gateway gear. So in answer to your question, we hedge our bets by doing both. We think that telco is generally rock solid, and we couldn't find a SIP provider that could compete with the pricing for the TDM-based solution, especially once you add in the cost of the bandwidth overhead for all those calls. We have a handful of the 4-port T/E cards, an old 1-port T card, and our trusty old TDM410 card. We're now in the league of a channelized DS3, which we break out into a lot of T1s with some nice Cisco gear. Google the Catalyst 3845 when you're big enough to need that many lines. _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- AstriCon 2009 - October 13 - 15 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
