SIP refers to Session Initiation Protocol, a Voice over Internet Protocol that enables you to run your voice calls over your data connection.
It is a dedicated connection from your provider to assure voice quality. As SIP trunks are provided via an internet connection they are exchange independent. This means you can keep your existing numbers, even when moving outside your current exchange area and costly divert options are avoided.
SIP trunks can often be deployed quicker and offer a lower rental than traditional ISDN services with the benefit of enhanced disaster recovery options. Deploying SIP trunking can be a big step towards simplifying your organization’s telecommunication and preparing for the latest real-time communications enhancements.
The amount of SIP trunks that can be provided to your building depends on the Internet connectivity.
Key Benefits of switching to SIP trunks:
- Flexible and scalable communications
SIP trunks can provide from two to a thousand lines, if required. And it allows additional lines to be activated in a matter of hours, rather than weeks as with ISDN.
- Eliminates redundant networks
Deploying SIP trunking is a logical step towards the goal of having a single converged IP-based network, rather than separate telephone and data networks.
- Reduces rental costs
With SIP trunks you can dispense with costly Analogue or ISDN line rentals and replace them with a service that can cost significantly less.
- SIP connectivity
A SIP trunk can be deployed over any internet connection that may or may not share bandwidth with other IP traffic. However, using a connection designed to support and assure the SIP service can typically carry a lot of simultaneous calls.
