Some of the most common features are listed below, but please speak to a member of our Sales Team for a complete list of supported features:

  • Web based management console

  • Auto Attendant/Digital Receptionist/Call Queuing & Management Statistics
  • Voicemail/Music on Hold
  • Call Twinning (Ring Extension & Mobile Simultaneously)
  • Soft phone integration

  • Group phone directory
  • Voice Mail to email notification
  • Multi-user conference call bridge


In order to make or receive a call, your handset or softphone on site needs to connect to the caller via the PSTN (Public Switched Telephone Network).  Spitfire has a unique place in the market as we offer a fully managed end to end solution to support the full journey of a call.

Your Hosted PBX 2.1 phone system is located in one of Spitfire’s secure data node facilities. From here it connects to the Spitfire SIP network; a network isolated from the public internet and purely dedicated to SIP voice traffic, with a direct interconnect to the PSTN.

Your office users connect to Hosted PBX 2.1 using a Spitfire voice approved data connection to assure business voice quality and provide a completely secure connected environment.  The call will be delivered to the handset or softphone to complete the route from the PSTN to your users.

Any remote users or branch offices may also connect to the hosted phone system using existing Internet connections, however please discuss these with us so that we can advise on how to assure call quality.

All handsets are pre-configured by our engineers and are set up on a ‘plug-and-play’ basis to make self-installation extremely straight forward.  For businesses located within the M25 we currently also include at no additional cost 3 hours of on-site installation!

Each user will have an extension on the system, with everything managed centrally on Spitfire’s network, regardless of their location. This makes adding user extensions simple and keeps lead times short, with handsets sent out ready to plug in and use immediately.



    With Spitfire? Extremely.  For a start Hosted PBX 2.1 is located in one of our secure core network nodes.  Not only do we build resiliency in to our server architecture but the node itself has been deployed with power and backup redundancy.

    Our core network has been designed to provide high availability for all inbound and outbound telephone calls. Not only do they connect via geographically diverse endpoints, but Spitfire also interconnect with multiple global Tier 1 wholesale voice carriers – offering unprecedented levels of reliability, up-time and call quality.

    When paired with a Spitfire voice-approved data circuit we are also able to offer a complete end-to-end service, not only assuring voice quality but also up-time availability.

    Spitfire have been providing hosted telephony, SIP and Voice over IP solutions for more than 10 years.  Cloud telephony is now the preferred option for nearly all businesses that we partner with.


    • Feature rich system – all features included so no expensive hardware or licence key add-ons if your requirements change.
    • Future proof upgrade and development path – Hosted PBX 2.1 is developed in-house and it’s feature set will continue to grow as your business does.  If for whatever reason your requirements go beyond the current capabilities of Hosted PBX 2.1, Spitfire can easily move you to our 3CX Cloud solution using the same telephone handsets. We have you covered!
    • Scalability – the system grows with your business so that you can add extensions as and when you need to.
    • Flexibility of location – download and use the recommended Bria softphone and smartphone app to work from anywhere.
    • Free of charge set up, low cost per user rental, cheap phone calls all with one provider for simple billing.
    • Free calls between extensions and other connected offices.
    • Easy to use online portal to self manage users as required.

    Hosted PBX 2.1 is designed to be a low cost self-install system and is easy for users or your IT department to connect by themselves.

    However for a limited time Spitfire are providing 3 hours of free on-site installation for businesses located within the M25.  Spitfire are the only hosted PBX solution provider on the market to offer free on-site installation and training!

    HOSTED PBX 2.1 vs 3CX CLOUD …

    Although both systems provide a great business quality hosted phone system, which is better suited to your business? Both systems are hosted within a secure Spitfire network node – so how do you choose?

    The main difference between the two solutions is the features that they offer.  Hosted PBX 2.1 is now the preferred option for most businesses although some will require a feature not yet available, as shown in the table below, when 3CX Cloud will be the recommended choice.
