Hello As an alternative to more expensive alternatives like OpenVox or Sangoma, I'd like to order an X100P clone from www.x100p.com for use in France. According to a PDF on the site, the reason this card gets bad reviews is that "the Silicon labs Si3012/Si3035 DAA chip used in the original Digium X100P card and low cost X100P clone cards only supports FCC mode. However, the Si3014/Si3034 DAA chip used on the X100P SE supports global line standards." As for software, "the Silicon labs Si3014/Si3034 DAA chip used in the X100P SE supports 600 Ohm impedance and complex impedance to meet CTR21 line standards. However, the Zaptel wcfxo driver only supports CTR21 mode with 600 Ohm AC termination, which may or may not be the correct setting depending on the country and the phone system in use." So... does someone know if OpenZap, which is apparently required in addition to Zaptel/Dahdi for FreeSwitch to work PCI TDM cards, supports CTR21? Thank you. -- View this message in context: http://old.nabble.com/Does-OpenZap-support-CTR21--tp26217371p26217371.html Sent from the Freeswitch-users mailing list archive at Nabble.com.
