I’m working with a 10.4.0 Asterisk system with GTalk for outgoing calls and we recently discovered that we can’t leave an outgoing voicemail. What happens is when we call any cell-phone (provider doesn’t seem to matter, tried AT&T and Verizon phones) and attempt to leave a voicemail it gets cut off after a few seconds with the message, “We’re sorry, either your connection was bad or you weren’t speaking. If you would like to leave another voicemail press…”.
There are no error logs or debug messages. There is no voicemail left on the end system. Voice calls all work well when the callee actually picks up but voicemails do not seem to work.
