Hybrid Voice

One of our closest competitors says, “Your Business Phone System is on-site or in the Cloud, it’s up to you.” If that’s all you’ve got in your portfolio then yes it is. But for an increasing number of Splicecom customers there’s a third choice; mix and match the best features of two common approaches to create a hybrid architecture offering the business benefits of both.

Combining a virtual voice platform in the cloud with flexible edge solutions – survivable on-site gateways, smaller soft/hard/virtual voice platforms and legacy connectivity options for existing analogue phones and non-SIP enabled PBXs - allows a single unified business-wide phone solution to be constructed across multiple sites, connecting office, mobile and home based employees on equal terms.

This unique hybrid approach provides total business continuity in the event of the primary system or IP trunks between sites failing, offering full call processing with local PSTN call break-out for every site.

A hybrid architecture requires all system components, be they implemented in software, hardware or as a virtual service and wherever they may be located, in the cloud or at the edge on the customer premises, to run the same voice Operating System (OS). Only when this has been achieved can a single truly unified hybrid system be achieved. Trying to combine Cloud/Hosted PBXs with customer premise solutions from different sources just won’t cut it.

Splicecom are unique in their ability to deliver a pure Hybrid architecture because we have migrated our field proven Maximiser OS to the cloud, as opposed to purchasing an existing system to meet this need. Because all of our products have been designed in house by the same development team, we can deploy the same operating system across all of our PBX solutions, be they soft, hard or virtual, wherever the may be deployed – on the customer premise, in the cloud or hosted. This ability to deploy Maximiser OS “everywhere” means that not only can soft, hard and virtual PBXs – and gateways - be mixed and matched, as multi-site requirements dictate, to form a single totally integrated business voice system, but architectures can too. This allowed us to deliver the first truly Hybrid solution, combining the strengths of both our Cloud and On-Premise and solutions.

A Maximiser OS based Hybrid Solution allows Splicecom customers’ to utilise IP trunking routed to their own virtual or cloud PBX. Typically the machine running this virtual service would be in a high reliability/high availability state, with dual servers, multiple disk drives, replicated infrastructure and trunks, etc. allowing fault tolerance, far in excess of that expected from a traditional IP PBX and associated services to be achieved.

The IP handsets deployed in very small offices or for homeworkers are networked directly to the Cloud based PBX. For larger sites, where higher availability is required, Splicecom’s 5500 NSG modules are deployed to run as survivable gateways and linked to the Cloud based PBX via IP trunks. These gateways provide local call break-out to ISDN and/or SIP services, handle on-site voice processing and call recording tasks and deliver complete, fully featured survivability in the event of the primary IP link to the Cloud PBX failing. Splicecom’s comprehensive range of Flexible Edge Solutions (FES) means that the S8000 Soft PBX family and 5108 and 5100 Hard PBXs can also fulfil this role allowing existing, long standing Splicecom customers to benefit from Cloud Voice as well – not just new ones.

Analogue phone gateways provide legacy handsets connectivity – and then energise the phones by allowing them to be used in conjunction with Splicecom’s Navigate Phone Partner app, delivering all of the advanced personal productivity features of Splicecom’s PCS IP Phones.

Even existing PBXs can also be catered for using Splicecom’s trunk gateways to provide ISDN or DPNSS connectivity. This allows these legacy enterprise systems to remain integral to your overall communication system, with each site being migrated to full IP operation at your own pace, as business needs and budget dictate.

And to help you make they deployment of Hybrid architecture even easier, Splicecom Select allows you to simply add the network infrastructure services you require to deliver a complete end-to-end Splicecom solution. Splicecom Selects offers three complimentary services; Virtual Cloud Servers, Site/Cloud Connectivity and SIP Trunk Services.


  • Site-to-site calls via the IP WAN
  • Total local site resilience with failover to local ISDN and/or SIP on Network Service outage
  • Ability to retain local “well known” ISDN numbers
  • Utilisation of the IP WAN for PSTN breakout via the Cloud based PBX
  • Resilient Call Routing at the Cloud upon Network Service outage
  • Route calls to alternative locations via the IP WAN or via ISDN/SIP services to the site with WAN failure etc.
  • Reduction in the total number of PSTN lines required across a multi-site deployment
  • Reduction in the capacity of IP Trunks required at the Central Site when compared to traditional multi-site networks.
  • Retention of analogue handsets, where required, through phone gateway - but with access to full IP telephony features utilising Navigate Phone Partner app
  • Retention of legacy PBXs and other enterprise systems using ISDN/DPNSS trunk modules
