I'm using an 2811 MGCP voicegateway as SCCP trancoder resource. Sometimes it run out off recources because communications manager isn't counting the resources corretly.
The values on the available resource I see on Communications manager and on the voicegateway are different. In the example below Communications Manager sees 2 in use while the voicegateway sees 0 in use.
A reset of the transcoder on communications manager fixes this but the problems commes back after a few hours.
C2811#sh sccp conn
Total number of active session(s) 0, and connection(s) 0
