Are you searching for answers about upgrading your tired, old telephone system? Maybe you are opening new offices and aren’t sure about embracing new technologies when it comes to telephones? You might just want to stop paying so much on your regular monthly telephone bill?

If your business telephone system is getting ‘a bit tired’, or your business is at that stage of needing a new telephone system, then it may be time to be looking at making the most of the advantages offered by VoIP and the cost savings it can bring.

There are 2 different ways of getting into the newer technology telephone system, and each has its pros and cons. Hosted PBX / Cloud PBX  and IP-PBX. Both use IP telephones, which connect via your data network to the internet. This can eliminate the need for ‘doubling up’ of cabling in the office environment – another cost saving. There is no longer a requirement for dedicated telephone cabling to each phone.

Most IP telephones contain 2 Ethernet ports – 1 port for the connection to the internet, and another port (called a pass-through port) for the computer connection.

Depending on the model of IP telephone, these ports can be Fast Ethernet (10/100 Mbps), or full Gigabit (1000 Mbps), so there is no detriment to the operation of the network connection to the computer. Simply unplug the computer network cable from the wall outlet, connect the telephone to the wall outlet, and plug the computer network cable into the telephone. Both devices are then operating off the one wall outlet.




All hardware for your telephone system belongs to you, and the main control box is on your site.
This also has advantages and some disadvantages.


  • The telephone system can be tailored and configured to your needs and the way you work.
  • You have control over the telephone system, and it’s day/night operation.
  • Easier to customise/personalise the message-on-hold, and other system greetings.
  • Wider choice of IP telephone makes and models (and prices).
  • May allow connection of analog trunks (via the ‘Phone’ port of your NBN router), as well as 3G/4G SIM card versatility.
  • May allow connection of normal analog telephones or fax machines, in addition to the IP telephones.


  • Main control box needs to be installed on one site, and is incorporated into the data network.
  • IP phones are either configured for ‘on-site’ or ‘off-site’ operation. You can have an IP telephone at home, but you cannot bring it into the office, and vice versa.
  • Main control box may require firmware upgrades to be kept up-to-date.

Pinnacle Phone and Data has done extensive bench testing and field deployment of the S-Series IP-PBX by Yeastar. This is an all-in-one telephony solution, feature rich PBX for everyday use.
