Hi Mike, Some instances where one of these will be null are: For an incoming call, the caller SP will be null if There is no cic-id when the call comes in or if the cic-id matches multiple org's and the org's have different SP's. For an outgoing call, callee SP will be null if Route selected is the default route. ISDN/H323 dialout is done to an unknown endpoint.

The API documentation says that "If the Cisco TelePresence Exchange System cannot determine a value for this field, the value is null."   Can you provide some additional information about when the CTX is unable to determine a value or when it is able to determine a value?
