For the industry of newly-announced telephone exchanges, the group telephone debugging must master some skills in order to be able to strategize in the communications industry.
1. understand the customer's needs, such as how many external lines, how many extensions, this is the key, for example, customers need 8 external 32 telephone switches.

2. understand the customer's function of the PBX, such as: recording tips, there are about 8 seconds, there are about 20 seconds, all should have differences, online recording function can be in the computer query, IVR voice navigation, there is a caller ID Functional, there is a special extension number programmed, manager of the secretary to the function.

After the telephone switch is normally opened and used, when it is in the maintenance operation stage, it often fails due to program operation errors. This requires the maintenance personnel to handle such failures in a timely manner to ensure the smooth communication. The so-called handling of failures can also be understood as the process of placing software control programs in a normal operating state.
When the telephone exchange software program is wrong or confusing, there is no time for the maintenance personnel to study the working principle of the software program itself. As long as the troubleshooting is implemented as soon as possible and the telephone can be promptly rushed through. The use of restart methods to quickly eliminate program failures has become a "magic bullet" for maintenance personnel. This is similar to the fact that when we operate a computer, when a "dead" phenomenon occurs due to a computer program error, no matter what kind of commands the keyboard is typing, the computer will not respond. At this time, the fastest way to recover is to "hot" the computer. "Start or "cold" start. Similarly, the telephone exchange can also use the restart method due to the need to handle its program failures.

For different models of different types of telephone exchanges, the operating mode and command parameters of the telephone exchange may be different when the program is restarted. However, the functions and types of the restart are roughly the same. It is nothing more than using commands to restart the software program or operating the hardware. The group restarts.

Many customers who purchased the group's telephone exchanges often ask our customer service: “Whether all extensions can use the outside line at the same time after installing the PBX switch.” For this question, the customer must have no accurate knowledge and understanding of the PBX. The Xiaobian of communication gave everyone a chance to read why customers have such an illusion.
The main reasons for the above illusion are as follows:

1. The customer mistakenly confused the PBX with the network switch! Users install a network switch to allow all the company's computers to access the Internet through the network switch, the network switch is about bandwidth, such as: 1M, 1.5M, 2M, 8M, 10M ..... and so on. Network switches are shared, many Taiwan's computer sharing of bandwidth is like an expressway, where every car has its own way. The telephone exchanges are not the same. All extensions can dial out the outside line only when there is a gap in the outside line. There is no restriction between the interiors. If there is only one outside line in the call (is a simulated ordinary telephone line), the "This user is in a call" tone will appear when you call again.
2. there are customers often see other companies, only one number was announced externally, but at the same time several or dozens of individuals can score! This situation is very common in daily life, such as 114,110,10000,95588. . . . . Such as: There are hotels such as hotel booking hotline and so on. . . . Many of these form numbers. In fact, it is in the operator such as: Telecom, China Unicom or Railcom, opened the "trunk" function.

Even though the Group's telephone exchanges already have dozens of development history in China, new users will continue to emerge. New users will always be accompanied by various questions when installing the PBX. In fact, this is normal and new users are resolved. Questions can be.
