SIP trunks & inbound calling
Voice Connectivity for business telephony.
SIP Trunks and inbound voice solutions replace ISDN/PSTN with scalable VoIP channels, number portability, self-service routing and QoS reporting – delivered over business Ethernet/nbn with resilient failover.
SIP Trunks
Scalable SIP channels (5–500+) for PBX to PSTN calling with QoS and MacView self-service.
Inbound Voice Solutions
Hosted inbound numbers with call forwarding, IVR, hunt groups and voicemail-to-email.
Number Portability
LNP for singles/100-blocks across 66 CCAs with IPND compliance.
Delivery Options
Native Ethernet SIP, ISDN IAD or supertrunk failover over diverse access.
What it solves
End ISDN with flexible voice connectivity.
Replace legacy PRI/BRI with SIP trunks and inbound services that offer LNP, resilience and self-management for multi-site telephony.
- ISDN migration: SIP Trunks provide feature parity (CLI, fax) with Ethernet/nbn delivery and LNP.
- Complex call routing: Inbound solutions enable self-service forwards, hunt groups and DR plans via MacView.
- Poor call quality: InView MOS/R-Factor reporting ensures G.711/G.729 performance over QoS links.
- Vendor lock-in: No-contract scaling, supertrunks and multi-access reduce dependency.
How it works
SIP trunks over business access.
Scalable trunks, inbound routing, reporting and resilience for PSTN replacement.

FAQs.
What is voice connectivity?
Voice connectivity is a business telephony service that connects your phone system to the PSTN using SIP trunks and inbound voice services, helping you manage calls more flexibly over Ethernet or nbn.
How do SIP Trunks replace ISDN or PSTN services?
SIP Trunks carry calls over IP instead of legacy ISDN lines, giving you scalable channels, number portability, better routing control and easier migration from older voice infrastructure.
What are inbound voice solutions used for?
Inbound voice solutions help route incoming calls to the right team or destination using features like hunt groups, call forwarding, IVR and voicemail-to-email.
Can I keep my existing phone numbers?
Yes. Number portability is supported, so you can keep existing numbers or ranges while moving to SIP Trunks or inbound services.
How does Macquarie Telecom help with voice quality and reliability?
The service includes reporting and monitoring tools such as MOS/R-Factor visibility, QoS support and failover options to help maintain call quality and resilience.
Who is voice connectivity best suited for?
It’s ideal for organisations replacing ISDN/PSTN, managing multi-site telephony, or needing flexible inbound call handling and scalable voice services.
