siptcpexamplecom

siptcpexamplecom is a placeholder domain commonly employed in networking and VoIP documentation to illustrate SIP over TCP configurations and message flows. It is not a live or resolvable domain and should not be used to host real services. The name is intended for instructional purposes, similar to example.com in RFC documentation.

In examples of SIP deployments, siptcpexamplecom may appear as the Request-URI user host, such as sip:alice@siptcpexamplecom or as the address of a SIP proxy or registrar. When used with TCP as the transport, the example demonstrates how a SIP signaling session is established on a persistent connection, typically using port 5060 (or 5061 for TLS).

Practitioners use such placeholders to show configuration snippets for servers such as proxies, registrars, or user agents. The domain helps illustrate DNS resolution, SRV lookups, and TLS negotiation without touching real systems. Important considerations include that SIP over TCP relies on Content-Length to frame messages and may require connection management strategies to handle multiple transactions over a single TCP connection. In production, the real domain would need proper DNS records and security configurations.

As a fictional construct, siptcpexamplecom has no official status and varies by document. Users should replace it with a real domain in any practical deployment.
