The focus of PhoneNet is ISDN equipped PBXs including Avaya Aura, NEC NEAX, NEC SV9300, NEC SV9100, Ericsson BusinessPhone 250, Alcatel OmniPCX, and more - all connnected with a common dialplan primarily with E1 QSIG trunks served from a Cisco 2921 ISR.

PhoneNet has PSTN connectivity and the main IVR can be reached on +61 2 8403 0000 or +1 770 252 8000. The IVR can also be reached from PhreakNet and TandmX on 791-0000 and C*NET on 61 2 471 0000 (with a ShadyTel number hopefully coming soon).
