StationInit , StationD Skinny Message
In the CUCM traces , you can find a lot of StationInit and StationD .
What are they corresponding ?
CUCM Real-Time Monitoring Tool
Real-Time Monitoring Tool (RTMT) runs as a client-side application and uses HTTPS with TCP to monitor device status,system performance,device discovery and CTI Applications in the cluster
SDI/SDL Call Manager Traces
For call processing under the CUCM , you can find 2 types of traces :
- System Diagnostic Interface (SDI) : SDI informations are traces from services and logs from run-time event.
- System Diagnostic Layer (SDL) : SDL informations are traces from services as CUCM , CTI Manager and it stores logs state transitions between the node.
Most of the time , SDI traces will be the traces where you can find all stimuli and all interesting call processing traces regarding your phones. With a little knowledge ,it is not very difficult to read these traces
SDL traces are the transition states between the nodes and they are used more by Cisco TAC
Route Plan Hierarchy
Just a little reminder to say that the logical decision to route a call is based on the following order:
Route Pattern => Route List => Route Groups => Gateway .
But take also in mind that the configuration order is the reverse path.
BHCA
The call load is referred to as Busy Hour Call Attempts ( BHCA) which is the maximum number of active calls during the busiest hour of the day .
Pattern * and # reminder
As reminder , don’t forget that in pattern expression , * and # are valid expressions.
So in fact you have 0,1,2,3,4,5,6,7,8,9,*,#
