Hi,
Did someone experience that Asterisk OS 1.2.5 voicemail issues?
Problem description:
Some one call to the extensions 200,
After 10 sec ring then go to voicemail 200 at default.
Announcement "Please leave me a messages.....blar blar.."
When I completed to leave a message...
IF :
I press the pound "#"key ...
Then it says "Transfer"
IF :
I Press the zero "0"key
Then it say "Please confirm your recording ...."
IF :
I hangup after leaving a message...then things get normal.

What is this????
