PBX Systems

Traditional PBXs would have their own proprietary phones, such that there would be a way to re-use these phones with a different system. This means that we either have system-lock-in (we are bound to the same system because changing system means also changing phones, which makes it prohibitively expensive to break away) or vendor-lock-in (we are bound to the same vendor because the phones are only usable with systems from the same vendor, sometimes only within a particular range of systems).

FCompared to newer systems, traditional PBXs can be very expensive to set up. In addition to the cost of the PBX hardware, you will also have to install traditional analog phone lines within and outside of your office if you don't already have them.

Switching to an IP PBX brings with it many benefits and opens up possibilities, allowing for almost unlimited growth in terms of extensions and trunks, and introducing more complex functions that are more costly and difficult to implement with a traditional PBX

An IP PBX may still rely on an analog phone signal once the call leaves your office, but it uses VoIP technology within it. The main advantage is an easier set up: you can use ethernet cables to connect your phones instead of traditional phone ones. That way, if you rearrange your office, you don’t have to do any rewiring.

Considering IP Telephone System, there are several advantages businesses can benefit. Some of the standard features are IVR, Voice Mail, Call Recording, Voice Mail to Email, Mobility Users, Call Queue, Conference call bridge, Telephone CRM Integration and Remote office connectivity. With IVR and call queue you can handle more calls with few staff on board. The Voicemail to email and Mobility options make sure you never miss customer reach even out of the office.

With an IP phone system all your internal telephony is routed through the existing LAN (local computer network). This way a separate network for telephony is not required. Even though the internal telephony is routed through the LAN, it is also possible to connect your IP-PBX via gateways to the PSTN. Of course, VoIP (Voice over IP, telephony via the internet) is also possible.

Since IP telephony is mostly using the open SIP standard, an IP phone system gives you a lot more freedom in your choice of phones. Basically any SIP compatible phone (VoIP phone) will work with an IP PBX. Furthermore an IP PBX doesn't limit the growth of a company. Since VoIP phones don't have to be connected physically to the phone system, it doesn't require a free port in the phone system like it used to be with traditional phone systems. IP phones can not only be connected via the LAN but also via the internet, using for example a VPN connection. Because of this, multiple locations and offices can easily be connected.
