SIPPIO is completely native to Azure and benefits from all the availability and redundancy features that comes with it. SIPPIO’s failover can be covered in different areas:

  • Geographical Presence: SIPPIO has servers in 10+ different Azure regions and will grow according to business grow. All the components have direct connection with each other on the Azure backend network, which according to Microsoft has less than 15ms round trip time.
  • Redundancy and failover on carrier:  The platform is connected to several carriersallowing us to have failover and redundancy at the carrier level. If a carrier fails, the system will automatically route the calls to the other carriers.
  • Redundancy and failover on routes: SIPPIO has an advanced mechanism for selecting the best and most efficient route for calls. The geographic spread across regions ensures calls are handled through the closest routing manager.
  • Redundancy and failover on SBC: SIPPIO leverages 10+ Azure regions and continues to expand. Our platform is dynamic and elastic to expand and shrink based on traffic load. All the connections are based on Names and FQDN. The system will automatically connect the end points to another region if the current Azure region goes down.
  • Redundancy and failover at Teams: By using SIPPIO, customers are connecting their tenant to an FQDN which is pointing to the platform. In the back end, advanced DNS features handle the traffic and connect customers to the closest region. If one region goes down, it will automatically connect customers to other available regions.


Yes! Today’s users mix and match their communication and collaboration ‘devices’ based on where they are, what they are doing and even whom they might be talking with. Users can make and take calls however they choose.

SIPPIO offers the gold standard of Direct Routing, Operator Connect Accelerator and Zoom Peering by offering a full end to end solution to enable voice in the cloud, using Azure, security best practices, and derived trunks to reduce direct connections and hardware. A full suite of automation tools ensure customers activate in minutes and partners can easily manage their voice practice to drive more value from investments.

In a cloud native solution, any necessary hardware is shared in a common data center which reduces overall hardware footprint. SIPPIO leverages Microsoft Azure to ensure the voice platform auto-scales to prevent idly running hardware, reduce cooling and other resources which makes for a greener data center.

SIPPIO suggests customers consider using computer speakers or headsets instead of phones to modernize the desktop and reduce plastics. This also provides a health benefit for users by improving posture and a productivity benefit by allowing untethered users to move more freely.

We also urge customers to recycle old servers and phones to ensure they don’t pile up in a landfill.
