SIP 200 OK vs 608 Rejected
SIP 200 (OK) is a 2xx Success response, while 608 (Rejected) is a 6xx Global Failure response. 200 indicates that the request has succeeded. For INVITE, the call has been answered. For other methods, the action has been completed successfully. In contrast, 608 means that an intermediary machine or process rejected the call attempt. Similar to 607 but the rejection comes from the network rather than the end user.
