The CallManager software does not provide a feature for call authorization and tracking codes. Perhaps this will be added in future version of CallManager.
There are a couple of options that you could try. First you can use a route pattern to simulate an access code for international calls. For example you could use 912345.@ where 12345 is the access code, pass the call to a route list and use a DDI of PreDot to strip off the 9 and the 12345 access code. This is really basic and does not provide any real security; users could simply tell each other what the access code is.
A second method is not create class of service restrictions using Calling Search Spaces and Partitions. Create Partitions for each type of call; emergency, local, long distance, international, etc. Then create route patterns for each type of call and map them to the appropriate partition. Next, create Calling search Spaces for each class of service you want; Local only, Long distance, International. Then place the apropriate partition in the Calling Search Space; Local CSS has the Emergency and Local Partitions, the Long Distance CSS has the Emergency, Local and Long Partitons, and the International CSS has all the partitions in it. Finally, place your phones in the appropriate Calling Search space for the class of service you want that user to have.
This method allows you to limit what phones/users can make long distance or international calls. There isn't a way to limit someone from using someone elses phone though.
The last method is to use either a telco service or a thrid party application to provide the access code based call restrictions and tracking. Most telco's can provide this service, where you simply pass the long distance or international call to the pstn and the telco prompts for an access code.
There are a couple of third party vendors that provide this service as a CTI application that integrates with CallManager.
