IVR : No sound. I can't hea anything

Asterisk Asterisk Support
1

Hello,

I’ve reccorded a voice message for the IVR. (.wav, 16 bits, 8kHz)
The file is /var/lib/asterisk/sound/11ivrrecording.wav.

When asterisk (1.2.5) starts this file i can’t hear it on my phone.

It’s a SIP phone (extension 11) which is on a switch with the Asterisk server.

Here is the log :

Apr 6 17:00:16 VERBOSE[845] logger.c: – Executing SetCallerID(“SIP/11-97b9”, ““Patrice” <11>”) in new stack

Apr 6 17:00:50 VERBOSE[845] logger.c: == Spawn extension (from-internal, *99, 2) exited non-zero on ‘SIP/11-97b9’

Anyone has an idea ?

Thanks a lot.

This could be a possible NATing problem. If you are not behind any NAT device then ignore this else refer SIP & NAT issues in voip-info site.

Thanks for your answer.

I’m not behind a NAT.

Asterisk and the softphones are on the same switch.

How about recording the file in gsm and see what happens.

Thanks for your answer.

I’ve test my microphone and it works.

I’ve created a new sip extension (‘40’) in a ‘test’ context.

[test]
exten => 40,1,Wait(2)
exten => 40,2,Record(/var/lib/asterisk/sounds/40ivr:gsm)
exten => 40,3,Wait(2)
exten => 40,1,Playback(/var/lib/asterisk/sounds/40ivr)
exten => 40,1,Hangup

When i dial 40, the record app begins. I speak the file is created in the directory. But it doesn’t go on. The file is 0 ko and there is no :
exten => 40,3,Wait(2)
exten => 40,1,Playback(/var/lib/asterisk/sounds/40ivr)
exten => 40,1,Hangup

I’don’t know what to do…

Thanks for your help.

If the Playback worked you will see this:

– AGI Script Executing Application: (Playback) Options: (/var/spool/asterisk/tmp/naturalvoice_0b5a8)
– Playing ‘/var/spool/asterisk/tmp/naturalvoice_0b5a8’ (language ‘en’)

both lines, and on your I don’t see the second line (-- Playing), so that means the file is missing, Asterisk doesn’t have access to read the file, or the file isn’t compatible…

No, the record never stops so it doesn’t go on to the playback application.

I’ve tried whith record(ivr:gsm|5|30) and it’s the same. The record never stops :frowning:

hmm…i cant see the line ASNWERING your call before you playback a soundfile… :wink:

Remember:
A call not answered cant listen to a playback file.

According to your log:
Apr 6 17:00:16 VERBOSE[845] logger.c: – Executing SetCallerID(“SIP/11-97b9”, ““Patrice” <11>”) in new stack
Apr 6 17:00:16 VERBOSE[845] logger.c: – Executing NoOp(“SIP/11-97b9”, “Using CallerID “Patrice” <11>”) in new stack
Apr 6 17:00:16 VERBOSE[845] logger.c: – Executing Playback(“SIP/11-97b9”, “11ivrrecording”) in new stack

there should be an
exten=> whatevernumber,3,answer
exten=> whatevernumber,4,playback(nameoffile.wav)

Either you convert to GSM or you supply the fileextension !
WAV isnt THAT good format on linux/asterisk, i would convert it to GSM.
