Hi, The call id just needs to be a semi-unique identifier. The method for generating this is application specific, so there are no requirements for this value other than it should be unique in space and time. A common method I see in many sip applications is to generate a random value most likely also containing the current time concatenated with the ip address or host address of the application that is generating the call id.
Example: "Call-ID: [email protected]" or "Call-ID: [email protected]" In that example imagine 0123456789abcdef is a base 16 sudo random number with a timestamp mixed in. You could use any base you'd like or come up with any form of more uniqueness.
