[Telepathy] Empathy not picking up Asterisk call

[FNB Mailing Lists]

I installed telepathy-sofiasip.x86_64 on Fedora15 and configured it to 
talk to an Asterisk instance.  I can dial the configured Empathy 
extension.  It rings and I click Answer.  The
"Call with ..." dialog opens but shows "Disconnected in the left most 
portion of the status bar.  Hangup and Redial are shown in the toolbar.  
Both the dialing extension and Empathy keep ringing until I click 
Hangup, and which point the "Call with..." dialog closes and the calling 
extension makes a disconnected beeping sound.

Why might Empathy not pick up?  Thank you.
