Hi,
we have a 3rd Party Attendant Console connected with a SIP Trunk to CUCM with a Route Pattern pointed to SIP Trunk.
Here is first the Call Flow:
1. External/Internal call to main number
2. Attandant Console Software and Cisco Phone Ring and the call is not be answered
3. Another Cisco Phone gets Call Pickup Notification and push Pickup
4. The External/Internal hear Queue music from Attendant Console and the 2nd Cisco Phone rings
5. 2nd Phone Answer now the Call and the external/internal Call Disconnects
6. 2nd Cisco Phone looks like its connected and time is counting
From the SIP trace of the 3rd Party Attendant Console i see a BYE Message from the Route Pattern Extension to the EXTERNAL/INTERNAL Caller and thats the reason why the 2nd Phone and the Caller are not connected.
Anyone have same behavior or similar?
Here is the BYE Message:
