Hi, I have to link an Asterisk Box with a PBX Matra 6501. System look like this : E1------Te110P Asterisk Te110P-----E1----Matra 6501-----Phones | | Ip Phones Incoming call from E1 will enter on asterisk, if incoming number is _800n then go to IP phones. In this case no problem. But if it's an another call i want to return call to my old MATRA 6501. I don't known in my dial plan how to send call to an outgoing E1 channel... Thanks ! Jeremy SALMON
