The user cannot resume this call on the user desktop phone. Possible Cause If the calling party receives a busy, reorder, or disconnect tone when the mobile phone hangs up, the mobile phone provider probably did not disconnect the media. No disconnect signals came from the provider. To verify this possibility, let the calling party wait for 45 seconds. After this wait, the service provider will time out and send disconnect signals, at which time Cisco Unified Communications Manager can provide a Resume softkey to resume the call. • Add the following command to the gateway: voice call disc-pi-off • For the Cisco CallManager service, set the Retain Media on Disconnect with PI for Active Call service parameter to False.
