Introduction to Hosted Voice

You may be relying on a traditional analogue or IP based Private Branch Exchange (PBX) telephone system in your organisation. If so, it could be time to consider moving to a hosted solution in order to benefit from what a cloud-based solution has to offer.

Hosted telephony is a telephone system that resides in the cloud rather than in your office. Calls are made and received over a public or private Wide Area Network (WAN) connection, and from there, they are routed to PSTN fixed and mobile devices. The calls can be made or received by a physical telephone on the desk or by a softphone which can reside either on a PC / Laptop, Tablet or Mobile.

You can benefit from many hosted telephony features; some of which can make your company more efficient, and these can generally be switched on with no disruption to your day-to-day business.

There are many benefits to hosted telephony and these include no costly PBX maintenance contracts, license and / or hardware upgrades. We are responsible for the hardware and software, including keeping the system up-to-date with the latest upgrades.

The cost of calling over your WAN connection has a lower overall cost and in some instances there’s free calls, such as between your sites. The hosted system gives you a huge range of features and can integrate mobile and other devices to be called alongside your desk phone.

1. Choose your user licences, group licenses and add ons.

With over 500 features, the functionality of the system can be overwhelming, so SAS combines different features into bundles to create a range of user licences; from a basic dial tone, which may be used for a conference phone moving up to office users who require voicemail. Soft clients on laptops that allow for Instant Messaging and screen-sharing provide a richer collaborative experience whilst remote workers can take advantage of Mobile, Desktop and Hot Desk licences providing them a consistent functionality across multiple mediums, allowing them to make and receive calls regardless of their location.

2. Choose different types of phones for your users

Phones and headsets are not a prerequisite, as users can use their PC or Mobile client to make and receive calls, however, the handset and headset are still prevalent on office desks, providing a richer quality of experience.

SAS provides a range of desk phones and headsets, as well as wireless handsets that are ideal in locations where mobility is key.

Desk phones

We offer a range of desk phones by Polycom and Yealink, with basic phones up to executive varieties with colour touch screens.



Conference Phones

SAS offers conference phones, again, from Polycom and Yealink, suitable for small meeting/huddle rooms up to large conference rooms. Entry level solutions support Audio Conferencing only, whereas more sophisticated models can be expanded to incorporate multiple auxiliary microphones and video. 


Wireless Handsets

For many Customers, the requirement to make and receive calls whilst away from their desk outweighs the additional functionality that comes with a fixed desk phone. SAS provide a carefully chosen set of vendors and solutions covering handsets attached to a single wireless hub to more sophisticated solutions that allow handsets to roam across 40 meshed base stations either on a separate DECT network or using an existing WiFi solution, normally used only for data.



For call centres or employees who simply spend a lot of time on the phone SAS provide a range of Jabra corded and wireless headsets compatible with Yealink and Polycom handsets as well as a USB version for your computer.


3. Get access to the PSTN network with SIP Trunking

SIP Trunking is much more than just an ISDN replacement. SAS offer the next generation of SIP Trunking to either support our hosted telephony solution or complement your existing on premise PBX.

We provide SIP Trunks direct from our BroadSoft platform, therefore enabling all of the hosted features to be delivered over the SIP Trunk. Key solutions such as Disaster Avoidance features to Call Analytics and Call recording can complement the premise solution and enable a hybrid model for easy migration to hosted telephony.

SAS can connect you to the BroadSoft platform and onto the PSTN in a number of different ways; either by using your existing Internet connection, taking into consideration the type of connection you currently have and the number of concurrent calls you require; via a new internet connection provided by SAS or via a private connection to the SAS network where we directly peer with the PSTN.

Unlike traditional ISDN (which is due to be phased out by Openreach by 2025), SIP Trunking is not limited to a maximum of 30 concurrent calls per connection. Nor are they restricted to just providing voice calls.

The SIP Trunking service can co-exist with your internet or private WAN connection making this more cost effective to combine multiple services on one access compared to ISDN which can only be used for telephony.
