Pabx and Telephones

The phone call is still the first mode of contact between a business and a potential customer in many instances. This means that having a reliable, state of the art PBX system is a crucial and vital decision for any organisation. As technology has advanced we have gone from analogue exchanges to digital and IP systems, it means that choosing your ideal phone system solution is becoming increasingly difficult.IP TELEPHONES DUBAI.

As a result, different types of businesses will get the most out of different PBX systems, depending on their size, average number of callers, and resources available for new equipment.

Traditional PABX

A traditional PABX connects callers through a few phone lines to multiple extensions. These lines were typically Analogue and/or Digital ISDN trunks from Telkom connecting to the same type of ports/interface card on the PABX. In some cases the vendor has evolved to support VoIP on a card which plugs into the PABX and VoIP-enables a legacy system so that customers can make use of VoIP calling for cheaper outbound calls. For the vendors who dont support VoIP cards, VoIP providers usually supply a Gateway which can connect to the PABX's using the same type of ports/interface card on your PABX, thereby replacing (or working on-top of) the lines which were connected to these ports. 


An IP PBX, like Avaya,  is certainly an upgrade to a traditional PABX. Investing in an IP PBX is usually more expensive than a traditional PBX but the overall Total Cost of Ownership (TCO) is much lower and the core systems do not have a life-span as these are typically software based which can upgraded to provide enhanced functionality and stability. An IP PBX is good for companies that want direct control over exactly how their PBX is configured in-house, and don’t want to pay subscription fees associated with other PBX options. 

Onsite vs. Offsite

Onsite systems (on-premise PBX) offer more direct control over the phone system’s operation. When a business needs to add, change, or delete a line from the system, it can be handled in-house. This may require a higher level of expertise from onsite IT professionals, however. Offsite, or Hosted, options may shift the responsibility for configuration and maintenance to a service provider. Direct control of the system may be limited, but a company’s IT staff may be allowed and trained to carry our basic adds, moves and changes.

Analogue/Digital vs. IP (Internet Protocol)

Analogue systems use traditional wiring and are generally distinct from a company’s computer networking hardware. IP-based systems are integrated into the same network used for sending and receiving e-mail, web browsing, and other online functions. Traditionally, wired systems had fewer call-quality concerns than early IP-based systems – though modern platforms on strong networks has greatly improved. Using IP-based systems often allows a company to have all its communication needs handled by one provider, simplifying billing and support concerns. 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. In most cases, 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.
