CVP 3.0 SR2
ICM 6.0 SR6
I have an internal helpdesk setup (callmanager trunk_xfer to CVP etc...), which has worked fine for 3 years except for one issue. This is an issue I have worked on before with vendor with no resolution. When internal user (CCM) calls the helpdesk (CVP) and the call is assigned to an agent, while the agent's phone is ringing the internal user hears silence instead of ringback. This does not happen on every call to the helpdesk, sometimes there is ringback. What does supply the ringback tone to the CCM user when CVP is involved (gatekeeper, gateways, etc.)and what configuration would need to happen?
