[asterisk-users] Asterisk 1.6 Displaying in Debug that it is playing a ulaw file using BackGround() but no audio is heard from the phone

[Joe Wood]

First off, let me first say that this is not a one-way audio problem.
Sometimes I can get 'her' to speak to me, other times I can't for a
long time.

I'm just using a very simple system to dump people into MeetMe().
Nothing fancy.

I do have the following in my modules.conf:

preload => format_mp3.so
preload => codec_ulaw.so
preload => format_pcm.so

My extensions.conf looks like:

[general]
autofallthrough=yes
static=no
writeprotect=no
extenpatternmatchnew=yes
clearglobalvars=no


[conference-calls]
exten => s,1,Answer()
exten => s,n,Background(welcome)
exten => s,n,Background(and)
exten => s,n,Background(thank-you-for-calling)
exten => s,n,Background(conference-reservations)
exten => s,n,Wait(2)
exten => s,n,Background(enter-conf-pin-number)
exten => s,n,WaitExten(10)
exten => i,1,Playback(pbx-invalid)
exten => i,n,Goto(conference-calls,9000,1)
exten => t,1,Playback(vm-goodbye)
exten => t,n,Hangup()

exten => ${EXTEN},1,Meetme(${EXTEN})

Has anyone else encountered this problem before? I saw one posting on
the listserv, but it said to add in the pcm lib and I did that and no
change.

Help.

Thanks a bunch,

Joe
