Sip Trunking

What is SIP trunking?

SIP trunk is a new technology that allows the company to replace existing analog or digital telephone lines with a data connection. Once connected, the company can continue to operate the same way as before, without changes in the handling of phone calls. SIP Trunk calls are made by both VoIP (Voice over Internet Protocol) and traditional telephone networks.


What are the benefits of using SIP Trunks?


SIP trunks are capable of providing many business benefits, the most common and perhaps the most important of which is the reduction of current phone costs. SIP trunks are offered at a lower rental cost than other analog or digital telephone lines and have the added benefit of routing calls outside the traditional telephone network, providing phone calls, especially if companies operate in different locations, as these calls are often free.


The SIP trunk also has the ability to operate without a geographical phone number, and area code codes can work freely wherever a data connection is available.


How do you connect with SIP trunks?

Important areas to consider when making a business connection to SIP roots can be listed as follows

Can your current business phone support the SIP connection standard? Many newer phone systems are likely to have SIP communications capability with a simple addition to the software license or hardware unit. However, if your phone system does not support SIP trunks, another solution is installed, the SIP adapter. The adapter module allows you to add your SIP trunks by acting as a interface between the current PBX ports and the latest SIP connection circuit.

How important is the real quality of your company’s phone call?

The SIP trunk can be delivered at a lower cost if you decide to share an existing standard data connection to route calls over the public Internet. However, because the connection is shared, SLAs from the provider and the SIP trunk call are unlikely to be applied. Quality can not be guaranteed as calls are outside the router’s control. If call quality is of paramount importance, you must provide a dedicated xDSL voice link. This will link your work to the MPLS data column, while avoiding the public Internet service that will then ensure sufficient bandwidth, and therefore the quality of service or quality of service (QoS).


Companies should also consider the maximum number of concurrent calls, inbound and outbound? If you are replacing an existing number of standard boxes, you may have an answer to that question. However, if you do not, calculations must be made to ensure that the SIP trunk circuit that is provided can provide enough bandwidth to perform the required calls. For your company’s phone system. As a rough guide, the SIP trunk call will require about 32 KB of bandwidth.


The resistance should also be taken into consideration when thinking about a SIP connection solution. A company may want to install a secondary data circuit to make calls if there are problems with the service provider or problems caused by broken copper fiber lines inside or outside the building, but this also applies to conventional telephone lines. .
