Synthesized Voice Not Working

[usdave]

When I test my OGM's with the simulator, everything is fine. When I test over the telephone line, everything but the synthesized text works (.wav's play, detects tones, and navigation is fine). Looking at my modem trace:

The modem trace suggests to me that IVM is starting and then, after a few msecs, stopping a wav file. Curiously, I also found during an earlier test, that IVM was playing a wav file even though that option was not checked. Last clue, from experience, I know that IVM will not play the synthesize text if it is playing a wav file.

 

And again, the synthesized text plays fine with the Simulator.

 

Anyone seen anything like this...and have a work around? using IVM 4.05, Agere modem, Win XP
