Amplify your communications with Alltel SIP trunking.

Expanded capabilities for existing phone systems through SIP trunking service.

Running a business is about your ability to minimise costs, as much as it is about making sales. With most businesses using only 30-40% of their phone lines at any time, it’s no surprise that entrepreneurs like you often look at communications when it’s time to cut back on costs. But how do you trim your expenses without decreasing your availability over the phone? Simple– through an Alltel SIP trunking service.

What is SIP trunking?

Session Initiated Protocol or SIP trunking, is an enterprise-grade phone service that lets you enjoy the benefits of IP telephony while keeping your existing phone system. Instead of bundles of cable linked to the copper network, your IP-PBX system connects to fixed lines and mobiles through the internet.

SIP solutions work just like any traditional phone service. Every staff member will still have a direct phone number, but without the need to pay a line rental on every phone. Your business only pays for the number of lines you need to use simultaneously, and those lines are shared between all extensions.

What are the Benefits of a SIP Trunking Service?

A business-grade phone service that minimises your cost.

  • Get the perfect balance between an on premise system and IP telephony with your SIP trunking service. Enhance the use of your existing phone system without spending on new equipment, through phone services and features delivered over the internet.
  • Enhance your communication efficiency by eliminating the need for separate voice and data connections. A SIP service lets you maximise your internet bandwidth by adding voice traffic to your existing service and eliminating line rental for lines you barely use.
  • Encourage collaboration among staff and across sites, with free Alltel to Alltel calls on the same account. At the same time, enjoy low rates for local, national, mobile, and 13/1300 calls.

A reliable voice solution for business continuity.

  • Connecting your system directly to the public network puts you at risk for security breaches, power outages, inclement weather, or any major disaster in your area. A virtual phone service gives you the option to redirect calls to alternate numbers in the event your office becomes inaccessible.
  • Our servers are located at multiple and redundant locations. As your SIP trunk provider, Alltel specialists are on-hand, 24/7 to monitor your system. This guarantees that if a server goes down or experiences a system issue, your phone service remains up and active.
  • Despite being a hosted service, your business retains full control over your phone system through a self-managed web-based portal. Add and move phone extensions, track your usage, or change configuration settings anytime as your needs change.

A scalable Business SIP service for changing needs.

  • Your Alltel SIP trunking service gives you enhanced call concurrency and call volume, along with on-demand scalability. Have the option to add or remove trunks as your business requires, without the cost of additional installation and line rental.
  • Customise your call flow and determine which phones ring by configuring your own redirection scheme. As your SIP trunk provider, Alltel can help you tailor a call solution that makes sure no customer call is ever missed.
  • IP telephony is built for the future. Through a SIP trunking service, you can access new features through an enhanced communications solution, without the need for further investment on equipment.

A robust enterprise solution that supports growth.

  • Expand your reach with virtual numbers that can be called at local rates from all across Australia. Encourage global connectivity and make business calls to outside Australia, thanks to low international call rates.
  • Connect multiple sites, remote workers, or work on the road with enhanced call redirection options. Program calls to ring specific extensions or mobile numbers when a specific line is engaged or down.

Direct in-dial or DID numbers.

Your direct in dial (DID) numbers are more than just regular phone numbers. These virtual numbers help widen your presence by giving you a ‘local’ business number for each area you operate in. What’s great about it is that customers that call your business are billed local call rates, regardless of where your office is physically located.

You have the option to get new numbers for your SIP service or keep your existing numbers (landline, VoIP, 1300 and 1800 numbers) by transferring them to Alltel.

What are the differences between DID numbers and extensions?

Many of our SIP plans provide different numbers of extensions and DIDs. While some use these terms interchangeably, these two should be differentiated.

DIDs are the numbers that external callers dial to reach you, while extensions are internal numbers for each of your office phones, faxes, and central voicemail boxes (called voicemail-only extensions). It is not necessary for the number of your DID numbers and extensions to be equal.

Every extension can have its own DID to be reached by external callers, while others may use a shared DID number (for example, a customer service team). You can even have DID numbers without an extension. These redirect callers to phones outside your system (for example a live answering service or mobile phone).

Requirements.

Is your internet connection up to speed?

Alltel SIP trunking is run over the internet, which means the clarity of your calls depends on the quality your connection. As a rule of thumb, you need to be able to sustain 100 Kbps up and down with less than 4ms jitter. You can determine the compatibility of your connection through a PING test.

You should get results of:

  • Line quality of good or above
  • MOS of 4 or above
  • Ping of less than 100 ms
  • Packet loss of 0%

Even with good results from a PING test, there are other conditions such as network and router capabilities that may impact your service which a speed test will not see. Heavy data users that work with large files or want 6 or more extensions may need a dedicated internet connection with sufficient bandwidth to support your requirements. Alltel-provided phones typically use the G729 Codec, which uses the following average amounts of bandwidth for audio calls:

1 minute call = 234 Kilobytes
1 hour call = 13.71 Megabytes

These estimates are for a single direction only and assume one phone being used. If your provider charges for uploads as well as downloads, you will need to double these estimates. Our business consultants will also help you determine how much bandwidth is needed for your service.

How does SIP trunking work?

Keep your existing IP-PBX system.

The lines of your IP-enabled phone system are consolidated into SIP trunks—digital channels that eliminate the need for analog lines for each phone.

Connect to your Alltel SIP trunking service.

Your phone system connects to your Alltel SIP trunking service over the internet. This eliminates the need to install lines from your PBX to the switched network.

Use IP telephony to make and receive calls.

All internal and external voice calls are carried over your data network. External calls are routed to the PSTN network through your SIP service.
