VoIP Telephones
VoIP phones connect to your Broadband (ADSL) via a router using a standard RJ45 connection. They can also connect via the USB port on your PC, which in turn needs to be on your broadband connection. This, in conjunction with the subscription to the services of a VoIP provider (or Skype, or similar) , allows the user to make calls and benefit from the savings and enhanced features associated with VoIP telephony.
IP PBX System Phones
If you have a PBX with VoIP, or IP extensions, you will normally require the dedicated IP PBX phone, or range of phones that are made for that system. These phones are all IP phones that are system specific they will not work on a basic VoIP or IP connection. Please make sure that you have the correct system and that you have an IP extension before ordering or contact us if you are unsure.
IP PBX Equipment
Traditional PBX phone systems are replacing their analogue (PSTN) lines (trunks) and digital channels (ISDN2E & ISDN30E) with IP (Internet Protocol) telephony. This will enable the user to make calls over the internet, via their LAN (local area / office network) using VoIP (Voice over IP). All this is ultimately through their broadband connection (ADSL or SDSL).
In order to migrate these systems to the newer technology, they will require new hardware. In some cases it may be a keycode, in others it will involve a new card or cassette to upgrade. This equipment is manufacturer specific.
A whole spectrum of these products are available to fulfil the requirements of most systems from all the major manufacturers.
