When Cisco Unity integrates with Cisco CallManager 4.1(3), the Cisco Unity port hangs after a blind transfer to Cisco Callmanager and the IPCC queue "Cisco Unity-CM TSP device (Cisco Unity port x): Failed blind transfer to extension xxxx. Reorder tone det
When a Cisco Unity server integrates with a Cisco CallManager cluster that runs software version 4.1(3) with Cisco Unity-CM TSP version 8.x, the Cisco Unity voicemail ports hang. When a call is made to the Cisco Unity, a reorder tone is heard. Sometimes the ports return to normal when the Cisco Unity Services are manually restarted.
When this issue occurs, this error appears in the event log:
Explanation: No response is received on port 11 when a blind transfer is performed. This is a serious failure, and most likely the parties involved in the call are disconnected. In some cases, further calls on this port are not handled correctly.
After the error, this warning appears in the event log:
Event Type: Warning Event Source: CiscoUnity_TSP Event Category: None Event ID: 109 Date: > Time: > User: N/A Computer: > Description: Cisco Unity-CM TSP device 15 (Cisco Unity port 11): Failed blind transfer to extension 37100. Reorder tone detected. If this is a persistent problem, it may indicate a problem on the Cisco Unity and/or Cisco CallManager. Verify that transfers are working.
This issue is documented in Cisco bug ID CSCsg83588. The bug is fixed in Cisco CallManager version 4.3(0.32), 4.1(3)ES87, 4.2(3)ES15, 4.2(1)ES40.2 .
