How Does SIP Trunking Work?

SIP trunking works with VoIP phone systems (Voice Over Internet Protocol) and is based on SIP (Session Initiation Protocol).

SIP, which is the basis of SIP trunking, is the standard communications protocol for voice and video in a Unified Communications (UC) solution across a data network.

SIP Trunking eliminates the physical connection to a phone company. There are no hardware, wiring, or circuit boxes to maintain for connection to the PSTN (phone service provider).

A SIP “trunk” is installed virtually over your business’s existing internet connection, therefore replacing the need for traditional analog phone lines.

Reducing multiple phone lines into a single point of entry drastically reduce charges for incoming lines and the IT cost associated with the maintenance of those lines. (Some organizations prefer to maintain standard lines for faxes and alarms.)

The minimum amount of sip channels we do is 4, then it is £5 per additional channel. You also can add/bundle multiple phone numbers and also call bundles to your Sip trunk.

Reduce Your Phone Costs

With no need to maintain a physical phone line and the cheaper cost of VoIP calls you’ll see the savings month on month.

Infinite Scalability

Let your setup grow as you do. With SIP it’s easy to increase the amount of Trunks as your business expands and lower rates apply for multiple SIP Trunks.
