[Asterisk-Users] Missing ringback tone on C7960

[Rich Adamson]

Just upgraded to stable CVS-03/20/04-11:54:56 

C7960 -> * C7960 (all on the same wire), call from on phone
to the other does not receive any ringback signal. Total silence
while the phone is actually ringing, then hear voicemail anouncements
after the 15 second timeout.

Was working fine before the upgrade.

Anyone else observe the same issue?
