Voice Connect is a both-way (inbound and outbound) voice access product to connect your site to the Public Switched Telephone Network (PSTN). You can take a traditional ISDN Primary Rate interface in addition to your Wireless Connect data service, or alternatively use your data service to connect your PBX to the PSTN using Voice over IP (VoIP). Local Number Portability (LNP) ensures no disruption or re-organisation of critical business functions.

Why have it?

Telephony remains one of the highest cost items in the technology budget of business enterprises. Incumbent telecommunications carriers have been able to keep line rental and call charges high because they control the copper pairs in the ground used to provide traditional voice access products such as ISDN.

Access to cheaper call rates is possible if you can connect wholesale into an alternative carrier’s Central Office (CO) rather than into the incumbent’s local exchange. Pacific Wireless has developed peering partnerships with Australia’s leading business-grade voice carriers and combined them with our carrier-grade voice transport technology to enable you to save money on your telephony budget wherever you are within our coverage area.

Customers wishing to retain their traditional PBX and voice interface can migrate seamlessly from their current ISDN Primary Rate provider to our ISDN service. Pseudo-wire techniques effectively connect your PBX directly to a traditional ISDN voice switch at the voice-carrier’s CO without impacting on the funtionality or setup of the PBX.

Alternatively, customers already using or considering a move to VoIP can choose to move away from traditional voice lines and instead leverage off the quality of our IP network to access the PSTN directly using the Session Initiation Protocol (SIP) standard for VoIP. End-to-end Quality of Service (QoS) and a direct IP connection to our partner’s SIP gateway (that does not pass across the Internet) are included as standard with our SIP service.

As an added bonus, customers with multiple sites can also take advantage of free ‘on-net’ site-to-site calls.

Why is it the right choice?

	Both inbound and outbound, can completely replace your existing voice access method
	Local Number Portability (LNP) allows you to migrate your telephone numbers, or new ranges can be issued
	Traditional Primary Rate ISDN (10/20/30) interface provides ease of migration and interoperability
	Go 100% SIP for functionality or add SIP to your current setup and save money with least cost routing
	SIP services are provided as grouped trunks of 5, 10, 20 or 30 ‘lines’ (concurrent calls)
	Very competitive call rates, both domestic and international, including free site-to-site on-net calls
	$0 setup and $0 line rental options
	Guaranteed, uncontended connections to our voice-carrier partners that do not pass across the Internet
	Both our SIP and ISDN voice pass across our network with our highest level of QoS
	Backed by the Pacific Wireless premium Service Level Guarantee

How do I get it?

Your sites need to be connected to our network in the Melbourne call collect area with the Wireless Connect access method. Your PBX will require either a Primary Rate ISDN interface or to be SIP compliant.

How does it work?

Traditional ISDN services work by using wires in the ground to connect your PBX to the carrier’s voice switch, which then routes and bills the calls based on the telephone number you dialed. Pacific Wireless ISDN can be viewed as working in much the same way through the use of point-to-point ‘pseudo-wires’ that are created virtually across our network using transparent TDM gateways. These are high-powered devices that concentrate their processing power on maintaining voice quality as they are not involved in call signalling, routing or billing.

Our ISDN service runs alongside your Wireless Connect IP data services and does not use or affect any of the bandwidth allocated to those services.

VoIP systems work by converting voice calls into IP packets either at the handset or at the PBX. If the destination is known by the handset (or PBX) to be available directly over IP, it negotiates a VoIP call directly with the destination using SIP. If the destination is not known, the handset negotiates with a pre-configured SIP gateway to send the call to it so that the gateway can determine how to next route the call (usually over the PSTN). A VoIP handset or PBX can be directly connected to a LAN and/or broadband network, but sufficient symmetric bandwidth and QoS is required to guarantee that call quality is not compromised by other traffic on the network. VoIP calls that traverse the Internet can suffer from variation in call quality and may also incur download charges.
