A port is a logical construct assigned to network processes so that they can be identified within the system.
The lowest numbered 1024 port numbers are used for the most commonly used services. These ports are called the well-known ports. Higher-numbered ports are available for general use by applications and are known as ephemeral ports. UDP and TCP commonly use port 5060 for SIP signally and port 5061 for TLS.
The Orchestrator’s SIP process expects to receive UDP and TCP-based SIP messages on port 5060 and TLS-based SIP messages on port 5061 (legacy customers may also use 5062 for TLS).
The source port for UDP-based SIP messages is usually port 5060 as well.
An alternate and completely different definition of a Port is a single trunk, call path, session, or voice channel between two network elements.
