On our sipXecs trial system we minimize the chance of such scenarios by using user aliases that are equal to the person's DIDs with dialing prefix. This ensures that the calls made using your colleague's DID are never sent to PSTN and are terminated locally. In the example above if the PSTN prefix is 9 then: 202 has alias 5551202 for the purposes of receiving incoming calls and it also has alias 95551202 for the purposes of resolving outgoing calls locally. It does not solve the problem entirely since one can still end up with a call between 201 and 202 via ITSP due to call forwarding or far end transfer.
