Investing in a telephone system is a big decision to make. It is also a minefield, with so much technical terminology requiring a PhD to understand. We’ve put together a few tips to help you.
Not only do you need to assess your current needs, you must look to the future. Here are just a few ideas to point you in the right direction:
- What type of phone system? – PBX, IP PBX, VoIP? PBX (Private Branch Exchange) is a traditional standalone system consisting of external phone lines, analogue phones going either into a router or straight into the wall socket. Ongoing maintenance can be more costly as an engineer would be required on site to assess any technical issues. IP PBX is a software based PBX phone system, ideal for small businesses that offers more on call features than PBX e.g voicemail, on hold, call transfer. VoIP is a system that enables voice calls over the internet. These systems, particularly hosted VoIP have lower ongoing maintenance costs as the systems can be accessed remotely. Whichever system you go for it is important to speak to a competent telecoms supplier and understand the real costs from installation through to maintenance.
- Line type – Is it standard analogue, digital or VoIP? This will be determined by the type of phone system you choose and other factors. See next points.
- What do you need to use your line for? Do you need lines for voice, fax, internet access, pdq, video conferencing?
- Concurrency of calls – How many users need to make a call at one time? This will determine the type of line you have. This is also of particular relevance when on VoIP as voice calls may be compromised if you are trying to run voice and data over the same lines.
- Scalability – Are you likely to have more users in the future? What are the implications, office space, telephone extension?
- Do you have Mobile users? If so, do you want to integrate these users into you telephone system. VoIP gives you more flexibility to do so.
- How do you want to manage your inbound calls? Do you want to automate call answering whereby an IVR system or auto attendant would manage call flows?
- Do you want to use your system to help market your business? Some telephone systems enable you to put in on hold messaging and report on your inbound calls so that you can assess the effectiveness of marketing campaigns.
Our recommendation is that you work backwards. Understand your business processes and workflow, then list out what you want from your telephone system and what your users need. Then you can decide on the right system to fit the bill.
