It all depends, FXO is never truly reliable with all the disconnect supervision / hangup detection woes. A FXO card works as well as it can but traditionally requires an echo canceler if you want quality that will not draw complaints from your best QA testers, your family for instance who expect identical quality to the PSTN. The Sangoma cards for instance have this. The good thing about an ATA is that it's self-contained and translates everything into SIP for you when you don't have room for hardware. It's not worth cutting corners on telephone quality when, in the end, you will replace it once you get enough complaints. On Wed, May 26, 2010 at 3:26 PM, GillesToo <codecomplete@free.fr> wrote:

Even if you get it working the reward is not worth the effort. You would experience a lot of echo and other problems
I read somewhere that the reason for those problems people often have with X100P cards (such as echo or bad far-end disconnect supervision) is that most of them have they use the Silicon Labs DAA chips Si3012/Si3035 which is only good for use in countries that use the FCC standard; Countries that use the CTR21 standard (Europe, and others) require the Si3014/Si3034 chips, which support global line standards.

I thought TDM cards were a better solution to connect an IP PBX to a landline. Why would you recommend an FXO-SIP ATA instead? And which brand/model of ATA is recommended for use with Freeswitch? -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/Out-of-curiosity-Why-not-use-a...
