Description:When making a call between say the echo test and a device (i.e. SIP/Zap extension) the audio quality is bad (distorted) if the call is initiated from a call file.

****** STEPS TO REPRODUCE ******

Bad quality:

Channel: Local/7014@extensions
Context: applications
Extension: 2600
Priority: 1

Good Quality:

Channel: SIP/7014
Context: applications
Extension: 2600
Priority: 1

Extensions.conf snippets:

exten => s,1,Dial(${ARG2},60,tT)
exten => s,n,Goto(s-${DIALSTATUS},1)
exten => s-NOANSWER,1,Voicemail(${ARG1},u)
exten => s-NOANSWER,2,Goto(default,s,1)
exten => s-BUSY,1,Voicemail(${ARG1},b)
exten => s-BUSY,2,Goto(default,s,1)
exten => _s-.,1,Goto(s-NOANSWER,1)

exten => 2600,1,Background(demo-echotest)
exten => 2600,n,Echo
exten => 2600,n,Background(demo-echodone)

exten => 7014,1,Macro(stdexten,7014,SIP/7014&IAX2/7014)

Interestingly, if I do the following:

exten => 9999,1,Dial(Local/2600@applications)

and just use 7014 to call it, the quality is fine.

Still the same if I use the /n switch

Is this a problem with l.4.22?  Also, what version of GCC are you compiling Asterisk with?

And to add further, what codec is used for your test call.

Sorry, the machine I was having the problem with is now in production and not having this problem - this can be closed out - I'll get it reopened if I see the problem again

Closed by request of reporter.  The problem is no longer occurring.
