Automatic Call Forwarding

Automatic Call Forwarding

Office telephone systems are often used by a large number of staff, and this often means that calls will be passed around, from team to team and from employee to employee; handling this process manually can be difficult, which is why an office can get huge benefit from auto-forwarding.

The automatic call-forwarding feature redirects incoming calls through a chain of alternative devices or extensions until they are either answered or are invited to leave a voicemail message.

When a call comes in, this will typically be routed to your office extension; if the call is not picked up, the call will be rerouted to your smartphone; if you are still unavailable, the call will be rerouted again, this time to a colleagues extension.

The precise chain of forwarding can be completely tailored to your particular phone setup, so you reduce the chances of missing important calls and improve customer satisfaction by increasing the number of calls that can be dealt with immediately instead of them having to leave voicemail messages and wait for call-backs. This will allow calls to be picked up regardless of the working location; whether your employees are on the road, on holiday or working from another location.

This function is not restricted to working hours, as it can also be used to redirect calls to an extension or dedicated voicemail outside of business hours.

  • Streamline office telephone processes
  • Divert calls easily and conveniently to provide 24/7 access
  • Forward calls to multiple numbers
  • Ring selected numbers either all at once, or at specified times
  • Complete choice over call-forwarding
  • Define call-forwarding point
  • Set rules for out-of-hours calling

An auto-attendant is the core of any office phone system. It’s the part that greets incoming callers, provides them with a list of options and routes them to the correct extension or department depending on the option they select with their keypad.

Auto-Attendants are increasingly popular with even the smallest offices, particularly those that don’t have employees dedicated to a reception role, lending the air of a much larger enterprise and making a highly professional first impression to prospective clients and customers.

Aside from the obvious benefits already listed, an auto-attendant system also provides a sense of professionalism. Although most business it still done between people, having this kind of system immediately introduces a sense of scale to a customer's interaction. The benefits and features below are excellent examples of why this sort of feature can help your business.

  • Automated extension transfers
  • Automated voicemail transfers
  • Automated messages and call options
  • Automated choices and options with menus

Voicemail To Email Transcription

Voicemail is a basic feature expected of every office phone system, but modern systems build on this basic functionality of recording messages by enabling a number of extra ways to work with such messages.

If staff are short on time with several messages to get through, it can be time consuming listening to each one in turn. A faster alternative is to have voicemail transcription set up: here, you can opt to have your voicemail messages emailed to you as regular text, allowing you to very quickly skim each message for the most pertinent information.

Voicemail to email functionality is an excellent way to improve office accessibility. This system allows staff to receive your messages wherever you are, and it allows for convenient and efficient responses, even if you do not have access to your phone system.

  • Read your voicemails for easy access
  • Stay connected with your business, wherever you are
  • Forward voicemails to colleagues in the form of transcripts

Telephone Headsets

Phone System Headsets

Headsets plug straight into office desktop phones and PCs hosting softphones (such as Skype), enabling virtually hands-free use of the phone for long periods or consistent use.

A headset is a great accessory for increasing the flow and efficiency of your office communications, and also helps to avoid the minor physical issues that can arise from extended use of regular phone handsets.

There is also a range of access-to-work accessories which can provide extra ease of use for staff with special requirements.

Headsets are especially useful in any office environment where staff need to be able to speak on the phone hands-free; this can often be most prevalent in sales environments, or customer services, for example, where your staff might be accessing databases on their computers whilst speaking.

Office Telephone System Dashboard

RingCentral Phone System Dashboard

There’s no more complicated and time-consuming administration of your office phone system with VoIP: everything can be managed from a single portal or dashboard, from updating contact lists and modifying the Auto-Attendant options and routing configurations, to adding new extensions and features for new employees and getting an overview of call usage and billing with a single click.

Since every aspect of the phone system is logged, you can easily generate detailed reports at any time to keep track of, for example, the call volume through a particular extension or the length of time a department spends on international calls. With this data at your fingertips, it’s easy to see where further savings and cost reductions can be made. And as there are no lengthy contracts, changes can be implemented and billed for on a month-by-month basis.

  • Streamline processes within the system quickly and easily
  • Maximise office efficiency with easy customisation options

Flexible Call Management

With voice calls moving into the computer domain, many new ways of manipulating a call are made available as standard that would have been prohibitively expensive or impossible with traditionally wired office phone systems. Here are a handful of the best features for making your office phone system work for you exactly the way you want:

  • Monitor let’s office managers and colleagues listen in on a call – good for employee training and conducting customer service quality checks.
  • Whisper is similar to Monitor, allowing you to listen in but also speak to the internal party without the external caller hearing you. Again, useful for coaching employees in customer relations, allowing you to provide discrete input to the conversation.
  • Barge is similar to conference calling functionality, in that it allows you to join an in-progress call at any time. This feature can be used to allow office managers to intervene in calls with more junior staff members, for example.
  • Record allows you to start recording any portion of a phone conversation by simply clicking a button. The feature creates an audio file that can be retrieved afterwards from the phone system server and reviewed, shared or archived. Useful for backing up the details of important conversations or for later sharing with absent colleagues.

Expand Your Office Phone System

Phone System Expansion

With VoIP office phone systems, extensions are “virtual” – all call data is being sent across the same computer network, so you don’t need individual lines for each office phone.

Because of this, it’s much simpler to add and reconfigure extensions as you grow your business and bring in new employees.

You can also add new features to the system by simply selecting them in the dashboard manager, allowing to tailor the details and functionality of your phone system precisely to the size and nature of your current operation. This also means you don’t have to pay for features you’re not using.

If you are interested in Telephone Phone System features, you may also like VoIP Phone Systems.

Monthly Billing

Office telephone systems are now much more like a subscription service than a hardware solution that you have to pay for upfront, house and maintain yourself. With this paradigm shift, the billing process is also simplified – and most importantly, bills are lower! Businesses typically save up to 40% on their local calls and up to 90% on their international calls; not to mention that internal calls and other VoIP-to-VoIP calls can be completely free.

Spread the cost of your phone service and equipment, and easily manage the whole process. A telephone system not only helps you to lower costs, but it also allows greater freedom to make your budget work for you in other areas.

Provider Responsibility For Telephone System Infrastructure

Phone System Features

One of the major reasons for traditional PBX phone systems being mostly the preserve of large corporations was that the cost involved in installing and maintaining the necessary hardware.

With the advent of cloud phone systems, this is all a thing of the past as the service provider takes care of the installation and setup, as well as all the maintenance and future upgrades.

This all means lower running costs for you, with fewer staff and less employee time needed to manage the office communications.
