BNS Group and Switch Connect partner to deliver the first dedicated cloud based T.38 Fax service in Australia

1 February 2022, BNS and Switch Connect announce the availability of a cloud based T.38 fax service to solve the issues customers face when migrating away from legacy telephony to solutions such as Microsoft Teams PSTN Calling.

BNS first identified the problem customers were facing in 2020 when customers were fast tracking Microsoft Teams for remote working and collaboration. Some of those customers decided to implement PSTN calling for Teams but found they had no fax capability and could therefore not completely replace their old PBX systems.

Customers particularly in: healthcare, finance and banking, insurance and government need to ensure that fax data handling complies with privacy and data sovereignty laws in Australia, so outsourcing fax to a provider is not allowed.

The solution was for BNS to find a suitable service provider who could deliver a SIP service to any cloud provider specifically designed for enterprise faxing;  then couple that with the BNS Fax server technology within the customer’s cloud tenancy.

“We selected Switch Connect because they offered a Ribbon Software based SBC in their cloud which was co-located at a tier 1 telecommunications provider in Australia” said Laurence Buchanan CEO BNS.

BNS being a Ribbon partner for many years with SBCs which it had deployed in large accounts over the years was very confident that the solution would work.

The design allows the customer to implement the BNS Fax server in their own cloud tenancy (AWS, Azure etc) and utilise reliable SIP communications to Switch Connect who in turn can deliver fax over the service with minimal jitter or latency.

“BNS has been a Teams Calling customer of ours for a while and we were constantly discussing the issues with fax and Microsoft Teams, we got to a point of saying we just need to build something that works and is reliable for our customers and also for BNS’s legacy on-premise customers.” said Rohan Milne Switch Connect CEO.

The solution allows:

  • The customer to maintain complete control and security of their fax images because nothing is stored at Switch Connect.
  • Switch Connect can host existing 1800\1300 fax numbers
  • Switch Connect can host existing normal fax numbers subject to porting capabilities at the customer end.

Switch Connect can also provide Teams PSTN calling as a service for customers wanting a PSTN service for their Teams implementation.
