hello, my name is Willian, i`m from Brazil. I`m using the elastix 1 month ago, and I have some problem with 0.6 release. When im talking with inbound or outbound call, with ZAP Channel, or SIP Channel, the elastix active automatically the transfer feature. And, if the telephone operator (telefonist), transfer a call to extension, this extension can't transfer the call to another extension, returing a message saying (The extension number XXX are invalid) and hangup thecall. how can i fix this??? And other question, can i upgrade de elastix, from 0.6 to 0.7 without reinstalling all system??? Thanks a lot!!!!
