Distribution telephone, how many internal lines can an external line connect? That is, how many extensions can I have in one number, and it doesn't matter whether each extension is dialed or not.

How many extensions can an external line be divided into depends on the model and configuration of the telephone exchange. For example, if you have an extension of 100, there are 8 external lines or 16 external lines. The number of outside lines depends on how many people your company needs to call at the same time For example, if you have eight external lines, you only need to match a telephone exchange with extension 100, so that calling this extension will not affect other extensions. There are many brands of telephone exchanges with this configuration to choose from. Domestic Guowei imports Panasonic NEC Siemens, etc.
