Record Element Fails - G711alaw - IOS VB

[Gerry O'Rourke]

When using a CVP Call Studio application with the 'Record' or 'Record with confirm' I get a bad fetch error.

This only occurs if I am using alaw and not ulaw.

CVP version: CVP11.5(1) ES=8 Build=75

I can confirm that if a convert all audio to ulaw and change codec assignment on the dial-peer to g711ulaw that the app works OK.

I can also confirm that this app seems to work 100% OK on alaw when using the VVB - which does not make 100% sense to me!

Anyone have any ideas?

I have also tried with IOS version: c2900-universalk9-mz.SPA.156-2.T2.bin

The current IOS version is c2900-universalk9-mz.SPA.155-3.M5.bin

Gerry,

What do you have in the element settings?   I assume you have mime type set to audio/wav;codec=g711alaw.

[Gerry O'Rourke]

Paul,

Many thanks. You assumed wrong! I didn't have that set.

That is working now with those settings.

I owe you a beer!

Settings

----------------------------------------------------

FileType=other

MIME Type=audio/wav;codec=g711alaw

----------------------------------------------------

Any ideas on why the application works OK with the default setting of FileType=wav when using the VVB (and using g711alaw)?

Gerry,

It's just a different VB with its own specific implementation of Record VoiceXML element attributes, presumably simplified to default to whatever the one globally configured codec option is.

Have credited the beer account, thanks.
