Techniques are described herein by which the Session Initiation Protocol (SIP) server overload problem may be significantly simplified by using a distributed system where transactions can be authorized and stored. For example, a technology like blockchain may enable a centralized, shared, and secure transaction database to be used to communicate SIP server overload information. SIP server overload information may be shared between servers that are part of a trust domain. The trust domain may be confined within a network or span across network boundaries (e.g., between enterprise edges / SIP trunk providers / SIP calling cloud providers).
