Hi All, I also checked the wiki https://wiki.freeswitch.org/wiki/Channel_Variables Is there any way to get the channel variables in PHP script? Then it will be very easy to handle the following steps according to the result code.

Also other result info, such as fax_result_text, then could provide more detail response info to the client. Thanks! 2014-03-03 sparklezou
