asterisk users - Mar 2007 - Festival works extension to extension, not on trunk

I recently got Festival performing Text to Speech on my Asterisk system.

It is working great when I call from extension to extension in the
house. But when I dial in on my phone number (which comes in on a sip
registration to a Sonus server), I can not hear any sound. The
asterisk box thinks it is playing the festival sound but I hear
nothing.

Any ideas?

Try Cepstral Swift?  The voice is much better.  As far as no audio, I 
don't know.  Do you answer the call before festival plays?  Do you have 
an IVR you can call to see if playback passes audio?

Thanks,
