Maybe this is an obvious one?
But I need to do a little debugging to confirm.
My assumption is that if using a gateway or cube and you are setting CVP for alaw that the Gateway audio files that you upload and store on the flash should be alaw as well.
e.g. convert the files such as ringback.wav to alaw.
i.e. The audio files on the IIS (Media) server and VXML Tomcat Server will be alaw.
and therefore, we shoudl also convert the gateway audio files such as ringtone.wav to alaw?
I assume so...
Anyone know if this is NOT the case?
Also - the CVP 11.5 ringback tcl script has the following in it.
#1.Playtone requires DSP’s. We sell bundles that don’t have DSP’s for VXML gateways. CUBE may also not have DSP’s. Can’t we force a media name so that we don’t default to playtone?
I assume that this is not accurate? Is it? i.e. that you need a DSP to play the ringback?
If so, if using CUBEs, it best NOT to play ringback on Cube but just use VVB server.
I will need to test to confirm.

Yes, replace the gateway wav files with A-law versions. There should be a set on the CVP media. Ringtone.tcl doesn't need DSPs; it plays media files. Playtone is a reference to the TCL playtone command which isn't used.
