No Ringing (dead air) on Some Outgoing Calls

When I call certain numbers (cell phones mostly), there is no ringing until the other side or their voicemail picks up… just dead air.

Is there any way to simulate the bellcore-inside tone (regular ringtone) while the destination is ringing?

I’m surprised I could not find another thread on this topic, as usually there are several for any problem I’m having. If the question has already been asked, I apologize.

I’m running FreePBX 2.10 and Asterisk 10 (latest non-beta). Thanks!
