How Mitel Phones Integrate with SIP and VoIP

Mitel’s IP phone systems are designed to integrate seamlessly with both SIP and VoIP platforms, allowing businesses to optimise their communication infrastructure. SIP (Session Initiation Protocol) is a signalling protocol used for initiating, maintaining, and terminating real-time sessions that include voice, video, and messaging applications. VoIP (Voice over Internet Protocol) allows businesses to make voice calls using a broadband internet connection instead of a traditional phone line.

Benefits of SIP and VoIP Integration:

Future Proofing

As technology continues to evolve, the traditional Public Switched Telephone Network (PSTN) and Integrated Services Digital Network (ISDN) are gradually being phased out. It has been announced in 2027 to cease support for these legacy technologies. By migrating to IP-based communication, businesses can future-proof their operations, improve productivity, and reduce costs.

Scalability

VoIP systems are easily scalable, making it simple for growing businesses to add more lines or users without costly upgrades.

Flexibility

SIP and VoIP enable remote working and mobility, allowing employees to stay connected from any location.

Advanced Features

Integration with SIP and VoIP offers features like video conferencing, voicemail to email, and call recording, all managed through a unified system.
