Benefits of SIP Trunking and Call Management

Cost Saving

Thanks to multi-modal communication capability, SIP trunking enables you to save more than 30% on your monthly telecommunications costs.

Trunk aggregation

By centralising and eliminating redundant connections, you are able to use idle connections in one location for calls at another, thereby offering increased flexibility over traditional PRI circuits.

Flexibility

Depending on the needs of your organisation, the ability to add or reduce connection capacity is simple, thereby increasing the flexibility of the service you provide.

Simplified billing

By aggregating all the voice and data services into one product, you can take advantage of reduced administration with simplified billing.

Quality

By keeping communications data on pure IP connections as opposed to T1 PRI connections, SIP trunking offers improved voice and video quality, delivering almost HD-like audio.

One of the main advantages of choosing Business SIP trunking from Xinix lies in the ability to have numbers from the dialing codes you want to be delivered directly to your office, regardless of location. The ability to centralise numbers from such diverse places as London, Manchester, Birmingham, and Glasgow to a single hub ensures that establishing a nationwide presence for your company is simple. Just specify the dialing codes you desire, and leave us to do the rest.

We make sure that the quality isn’t compromised in any way. Each IP data packet arrives in the correct order and without delay, one after the other. Thanks to SIP trunking services from Xinix, this steady stream of delivery means that packet loss, time delays, and interruptions in delivery are never experienced. But, the question is how do we achieve this?

If you’ve ever experienced delays or problems in communication over IP, the most common issue stems from your internet service provider being unable to guarantee that your data will be forwarded onto your ITSP without delays. Instead, it’s often the case that your data will pass through some networks before finally reaching your ITSP, with a corresponding deterioration in quality.

With Xinix, we ensure that there are no such issues. As a provider of multiple services needed for successful communication, there is no delay or any glitches experienced in quality. Our SIP trunking services guarantee the same ISDN30e call quality, along with the ease and value for money to keep your business at the forefront.
