SIP trunking happens to be a Voice over Internet Protocol (VoIP) platform. VoIP is a way to use your web access to make phone calls. Remember, the internet is only able to convey computer data (digital data: zeros and ones). Therefore, I will try to answer the question of what VoIP is, and as usual, I will try to make it simple and understandable by all.

The bandwidth of an ISP is divided by the number of subscribers, so as the number of subscribers increases, the bandwidth for each subscriber becomes smaller. Also, the bandwidth allocated to each subscriber must be greater than a certain capacity to provide a subscriber with quality service. Most companies or administrations get their blocks of IPv4 addresses from an ISP. Also, view this link for more data.
Please note that ISPs are required to specify before the subscription the actual speed that the customer will benefit from based on the characteristics of its line with the mention “Your download speed will be between x and y Mb / s.” However, if you use DSL, the further you live away from the telephone exchange, the lower the actual rate will be. Some sites can compare at a glance the offers of all ISPs. Also, view this link for more data.
Among the different formulas available Internet Service Providers (ISPs) offer more and more types of subscriptions and methods to access the net. Remember, an ISP is not required to provide its former subscribers a new offer or promotion. Multiple connections to the net backbone are among the technologies used by ISPs to ensure reliability.
Remember, Tier 3 ISPs rely on Tier 2 ISPs to provide net access. Also, remember that the internet and the telephone network are entirely separate networks. However, if your line is not unbundled at an ISP, you will not be able to benefit from its most exciting offers.
For customers, the significant disadvantage of a Tier 1 ISP remains its high cost to access services. Compared to Tier 1 ISPs, the main drawback of Tier 2 ISPs is slower internet access. Small businesses most often use Level 2 ISPs.
For customers, the main benefits of a Level 1 ISP are reliability and data throughput. We speak of backbones, as these are the most significant links connecting the operators to each other. Remember, the customer needs connectivity and technical support.
Also, it is possible to terminate your subscription without charge if the ISP has not complied with its obligations or has increased its rates. You may also wish to end your subscription with an ISP if there is a legitimate reason These reasons may include a transfer, moving, a loss of employment, etc.
Beware, however, as with some fiber ISPs a fiber cable stops at the foot of the building, and the connection continues through a coaxial cable that tends to limit performance. You will also be able to keep your fixed telephone number for VoIP if you stay in the same primary dialing area. Remember, the telephone network (also called PSTN for public switched telephone network) can only carry audio signals.
