hello, rcuadra:
are you using elatix? if you are using pure asterisk+zaptel, you can download the patch tar files. get it from:
www.openvox.com.cn/downloadsFile/D110PG_driver.tar.gz
it has different versions of wcte11xp for different zaptel versions. you select a right one to replace the old wcte11xp.c in zaptel folder. due to design reason, the d110PG uses a different chipset, so we need a patch for that.
Regards!
