Airbus Defence & Space found its solution in Bicom Systems PBXware Multi-Tenant which provided simplified multi-tenant management and was customized to meet the needs of satellite clients. The custom work enabled the group to connect remote Cisco SIP Gateways to SIP Extensions in order to make and receive calls from remote offices.
Their remote offices require a low-bandwidth solution which can be either Centrex, for small sites, or remote IPPBX, for larger sites. In this case, the solution is based on the M1000 or M2000 appliances. This solution permits traffic to stay locally on short or far reaching WANs rather than having to use valuable bandwidth of the satellite service but that users can connect or be connected directly with their HQs using the satellite.
Local users can make outgoing calls to external numbers, local DIDs, on-net numbers, and extensions within the tenant. They can receive incoming calls from DIDs assigned to them, on-net numbers that are mapped to them, and a given extension’s range that is mapped to that SIP extension.
The system includes hardware redundancy in the Airbus Group Data Center which ensures a five-nines delivery for life-critical missions. Call quality is monitored by sipMON, a VoIP monitoring and troubleshooting solution that analyzes and records SIP calls in real time. sipMON helps to track the latency on the satellite and maintain an optimal quality of service.
