:Reduce telephone charges
:Connection of Branches: The connection of branches in several ways is as follows
Branches that have a central : In this design, there is a separate central boom that can be connected to each branch by connecting each central to a device called FXS or FXO and connecting it to the Internet, as shown below
According to the above form, the internal 102 of branch 1 of the telephone on its desk can dial and converse the office 201 of branch 2. Due to the fact that most companies have a central phone, this method is one of the least costly designs for connecting branches without changing the company's telephone structure. This type of telephone system is called the VOIP and the central integrated system.
: Branches that do not have a central
a). Companies that are just starting out or still have a centralized telephone system can either operate according to Scheme 1 (VOIP and Central Integrated System) or use VOIP systems in all branches
Branches who do not have a centralized telephone system
As per the above figure, each company has its own system of wipes and can connect to each other via the Internet. Regarding the above figure, ordinary phones are connected via a telephone wire to a device called FXS, and the urban lines connect to a device called FXO and can use external FXO to call outside the organization. Due to the fact that the two branches are connected through the Internet, they can receive an internal call; this method is one of the most costly and especially for companies that want to use Wi-Fi capabilities.
:b) Use of networked phones
This scheme costs less than plan A if the number of domestic branches in each branch is low. Ip phones have better sound quality than ordinary phones, and faster calling than regular phones.
