BigAir Australia is intent on eliminating legacy PSTN and ISDN lines with the release of VoIP services over wireless for businesses.

BigAir’s wireless last mile network and the company’s new IP-Centrex services, businesses can do away with their reliance on traditional phone lines thereby cutting communication costs, and also access a range of high-end PABX features including voice mail, interactive voice response (IVR), auto attendant, call grouping and transfers without the need to invest in expensive PABX systems.
“We have a solution for businesses looking to reduce their monthly calling costs and expensive line rental costs. BigAir’s new business-grade VoIP and IP-Centrex services provide significant savings and at the same time provide SMEs with advanced telephony features,” said Jason Ashton, joint managing director, BigAir.
BigAir provides IP phones from $250, which include PABX functionality and competitive call rates including 10c local calls, and 10c un-timed long distance to capital cities including Sydney, Melbourne, and Brisbane. Calls to fixed lines in popular international destinations like the USA, UK, HK, and Japan are 5c per minute.  A fully featured in-dial number is available from $5 per month, and this is able to replace a more expensive traditional phone line.
As part of its vision for the 100 percent wirelessly connected IP office, BigAir also offers web hosting, email services, Virtual Private Networks (VPNs), along with its business-grade high-speed broadband services.
