Symptoms

When issuing SIP control messages that exceed client connection limits, the connection count is not decremented after the existing connection timeout.

Impact

Subscriber encounters the client connection limit and all traffic from the subscriber is rejected. New connections cannot be established until the 'client count' times out 5 minutes later.

Conditions

When LSN pool client connection limit is enabled with SIP.

Workaround

None

Fix Information
