[asterisk-users] Pri-Debug-Log / Is Early Media supported by provider?

[Thorsten Göllner]

Hi,

I tried to use Early Media:

exten => 1,1,Playback(demo-thanks,noanswer)
  same => n,Hangup()

But when calling my extension I do not hear the voicefile - I only hear 
the ring tone. In the Asterisk-Log I can see, that the voicefile is played.

I got the same result when using "Progress()" in the first priority.

I tried "pri set debug on span 1" and got the following:

Can you see, if my provider supports Early Media? Or do I have to ask 
the tech department there?
