Hi,
Ii’ve red a lot on voip-info.org but I don’t understand the difference between these two extensions
- exten => 3,1,Dial(SIP/03397547XXX@swyx,20,rt)
- exten => _0.,1,Dial(SIP/${EXTEN}@swyx,20,rt)
What change?
If i call by “3” anything goes very well.
If i call direct by number 03397547XXX, my phone rings but when i answer I can’t hear anything 
Help me!
Thank you!
Giulio
