Experienced Voice Specialists

Simtex is a division of Zettagrid. Simtex specialise in providing flexible and reliable VoIP solutions for business. We started in 1996 as a dialup internet provider and now span the country with business-grade SIP Trunking network and Cloud PBX platforms hosted in data centres in most major capital cities.

Australian Originated Calls

Simtex has direct voice termination to multiple tier 1 carriers in Australia – we never send calls overseas unless of course you are calling overseas!  Many low-end VoIP providers in Australia take advantage of cheap Australian calls originating from overseas networks.  This means calls are sent overseas then back in to Australia (low prices with awful voice quality and a severe lack of reliability).

Depend on us

Our core VoIP infrastructure is powered by Cisco with complete failover redundancy. We also own and operate our own Cisco and Juniper driven fully-meshed MPLS core allowing us to provide dedicated, reliable and secure inter-office networks across the nation. Seventeen years of growth and development combined with our highly experienced network engineering team has produced a robust and stable national IP network.
