Does OpenZap support CTR21?
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.
This would be specific to the zaptel driver for that card, not openzap. mike On Nov 5, 2009, at 1:43 PM, Fred-145 wrote:

Thanks for the feedback. I've never installed this type of card with Freeswitch. Am I correct in understanding that I just need to download and compile the latest Zaptel/Dahdi source from the Asterisk web site, and then install Freeswitch and OpenZap, and it'll work (provided the card works with my hardware)? -- View this message in context: http://old.nabble.com/Does-OpenZap-support-CTR21--tp26217371p26230864.html Sent from the Freeswitch-users mailing list archive at Nabble.com.

Yes, it should just work. I'd recommend Dahdi (complete), because Zaptel is not being developed anymore. Check the wiki for little things you have to set in various files, such as /etc/dahdi/modules /etc/dahdi/system.conf wherever/freeswitch/conf/openzap.xml wherever/freeswitch/conf/zt.conf (shouldn't have to change it) wherever/freeswitch/autoload_configs/openzap.conf.xml -- Russell Mosemann ________________________________________________________ Concordia University, Nebraska See http://www.cune.edu/ for the latest news and events!

Thanks for the links. Turns out this card seems incompatible with the motherboard I have, so I'll concentrate on the Linksys 3102 instead. -- View this message in context: http://old.nabble.com/Does-OpenZap-support-CTR21--tp26217371p26320837.html Sent from the Freeswitch-users mailing list archive at Nabble.com.
