Ring Out, Connected, but no ones home.

Unanswered Question
Mar 31st, 2008

Problem: Calls placed, the number can be dialed on/off hook, the display will indicate Ring Out and then Connected, but nothing is heard--no digits dialing, no party on the other end, etc. But the called party can hear the caller. Sometimes takes anywhere from 1-3 times to get call to go thru.

Also happens occasionally on inbound calls. We can receive the call and hear the caller, but they cannot hear us.

Also should mention phone firmware was updated to latest revision, but the CM is still at version 4.0.2. Cannot see where ciscocm.4-0-2a-sr2b.exe was applied.

Management does not want to spend time and resources to upgrade up to version 4.3 at this time, looking to replace both CM's in coming year to v6.0.

Are these calls being initiated by a IP phone or analog phone connected to the ATA?

Is this happening to all phones? certain models? analog phones?

sounds like you have a one way audio issue. This is often network related but since you have made some upgrade's the first thing I would check is for any bugs with the CM version and firmware that you are using.

HTH, Please rate

This is happening on all IP phones (we use nothing but Cisco 79xx). The ATA's are used faxing, alarm control panels, etc.
