[asterisk-users] Festival works extension to extension, not on trunk

[Chris Carey]

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?
