Hi, i want to define some call groups like: extensions.conf [globals] GROUP1=IAX2/idefix&SIP/200 [capi-in] exten => 55,1,Dial(${GROUP1}) exten => 55,2,Hangup But Dial will not dial the defined numbers. exten => 55,1,Dial(IAX2/idefix&SIP/200) works fine. What is here wrong? Or is there a better way available to do it? Best regards, Matthias
