SIP Trunking

A method of sending voice and other unified communications services over the internet.

Session Initiation Protocol (SIP) Trunking is the digital successor to traditional ISDN lines. It connects your Private Branch Exchange (PBX) to the Public Switched Telephone Network (PSTN) via your internet connection.

Why SIP Trunking?

SIP Trunking eliminates the physical connection to a phone company. There is no hardware, no wires to maintain, and no technician visits to install new lines.

Key Benefits

  • Scalability: Add new channels instantly without waiting for hardware upgrades.
  • Reliability: In case of an internet outage, calls can be automatically forwarded to mobile phones.
  • Cost Control: You usually only pay for what you actually use (pay-as-you-go).
