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?
