Metro Voice services explained

Our Metro Voice service provides a private Layer2 managed access intended to replace your basic or primary rate ISDN services. We recommend Metro Voice for customers using with more than five handsets via either onsite IP-PBX or handsets connected to our Hosted Voice. The service is delivered in four basic flavors:

  • ADSL – VLAN: for hosted voice customers
  • ADSL – IP PBX: for customers with their own in-house PBX
  • EFM – IP PBX: for SME customers replacing a PRI IDSN 30 service
  • Fibre: For corporates replacing multiple PRI services.

A Metro Voice service resolves VoIP quality issues associated with sharing a single internet service for both Voice and Data.

1. The VLAN2 Service

The Metro VLAN2 config is designed for 2talk Cloud PBX hosted voice customers. Another words you’ve got your own phones with no onsite PBX.

The basic concept of our Metro VLAN2 config is sharing your office Ethernet wiring with a 2talk Cloud PBX router, while at the same time maintaining separation between your existing network and the 2talk Cloud PBX router.

This configuration has the following advantages:

  • Pre-configured router: With a couple of simple Ethernet patches you can easily deploy your own system without needing to contract a specialist IT contractor.
  • DHCP: Supports up to 20 handsets against the 2talk Cloud PBX routers
  • Shared Ethernet: Share a single Ethernet cable to each desktop, enabling both the MAC or PC to share the phones on-board switch.
  • Cost: Australian ISDN pricing is enormously expensive with a single basic rate (or BRI) 2 line services roughly the same as our ADSL Metro Voice service which by comparison more than quadruples a BRI capacity (supporting 8-12 simultaneous calls).

How To

  • Ensure the phones have been configured with the VLAN2 tag. While this sounds difficult, if you’ve got either a Polycom or Cisco handsets use our online provisioning platform.
  • Shared Ethernet: If you intend to share the desk Ethernet cable, you’ll also need to connect the 2talk Cloud PBX router to your Internet router or gateway. Always use the port 0 or FE0.
  • Restart your phones and the VLAN2 tag will find the 2talk Cloud PBX router, while your PC will ignore our router and register as normal back to your internet device.

2. IP-PBX Configurations

This configuration can be provided via ADSL, EFM or fiber optic for the larger enterprise customers. The decision to use one or other of these services is normally determined by organisation size. To size an appropriate service speak with a 2talk Cloud PBX sales person or your reseller.

Our Metro Voice IP-PBX provides a static WAN IP address with LAN addressing on for the default gateway and for your statically assigned LAN address.

SIP Peering vs Registration

Subject to your PBX supporting it, we recommend SIP Peering over Registration notwithstanding that our Metro Voice configuration supports both.

3. Metro Voice – EFM / Fibre

How To

  • Equipment: Our EFM service is provided with an “network termination unit” or NTU and secondly a pre-configured EFM router from 2talk Cloud PBX. Each unit will be clearly marked a) NTU and b) 2talk Cloud PBX EFM router
  • Network ports: Run a fly lead from FE2 on the 2talk Cloud PBX router (WAN PPPoe) into any port on the NTU.
  • IP Address: Our standard address range applies – as the default gateway and as the statically assigned address for your IP-PBX.
  • SIP Peering customers: If you are SIP Peering with us don’t forget that you will need to set the WAN IP address within your 2talk Cloud PBX portal.

A few things to note

  • What is it: EFM is inherently more reliable than ADSL and is ideally suited to voice for its lower error rates and its equal up and down data speeds (or synchronous connectivity).
  • Installation process: Following your order we commission Telstra wholesale to install the service between the closest exchange and your premises. Once installed the second part is installing the Network termination unit (NTU) into your building with one end patched into your MDF while the other presents an Ethernet port to which we patch a simple Ethernet fly lead into a 2talk Cloud PBX EFM configured Cisco router.
  • What about Cost: While it is more expensive than ADSL, its cost is normally 1/3 of a comparable PRI ISDN services that it replaces.
