Short for Session Initiation Protocol, SIP is a communications protocol which signals and controls multimedia communication sessions. As a result, internet telephony for voice and video calls, and instant messaging, can be delivered through this service.

Cellular Solutions has partnered with a leading SIP trunk provider to offer a SIP solution that supports connections from two channels for businesses with small PBXs, to multiple channels for large enterprises and contact centres.

Flexibility and resilience

It’s quick to install and offers a robust business continuity service that ensures your business never loses any calls. SIP trunking provides a phone service that will cope with any situation and gives you business grade resilience for your telephony. Whether you need to keep your business running in a disaster or emergency or you need to load balance your calls between sites during peak hours.

We offer SIP trunks that are ideal for businesses with seasonal voice capacity requirements where more lines need to be quickly and easily implemented with no long-term commitments, for example when running sales campaigns or during major sports or entertainment events.

Business relocation number flexibility with SIP means that you can keep your existing number, even when moving out of the area, saving you costs on printed company literature and stationery whilst maintaining the perception that you still have a presence in the area you’ve moved from.
