A smart way to stay connected

Business SIP uses SIP Trunking, virtual connections to the regular telephone network, that enable you to make calls over a TasmaNet data connection using your existing on-site PABX equipment. 

SIP Trunking is the simple, cost effective upgrade every PABX-equipped business needs to stay connected as traditional ISDN is disconnected.

Flexible and scalable

Each business location is allocated one or more SIP Trunks that can support from 2 - 100 simultaneous calls, making Business SIP ideal for organisations with a number of branches or remote workers that need dependable, collaborative communications. 

Call capacity can be quickly upgraded as your business grows, so that you can keep using the features of your business PABX without ISDN.

Business grade connectivity

Business SIP is powered by TasmaNet Business Internet so your voice traffic uses the same high quality, uncrowded connection as your data. TasmaNet is an nbn™ Wholesale Service Provider so we can optimise your connection with enhanced Traffic Class options, ensuring that your voice and video calls always receive dedicated bandwidth.

The time to upgrade to SIP is now!

Don’t put your business on hold! ISDN telephone services are disconnecting in Australia from mid-2019.
