From the phone directory data base you can build your VOIP dialing directory. For example, if a
person in our typical VOIP network at the headquarters picked up a telephone (for example extension
4123) and wanted to talk to some one at the Sales office, they would dial one of the four
headquarters extension numbers (4, 5, 6, or 7). It makes no difference which extension you choose,
because they all get you to the headquarters multiVOIP. A second dial tone is heard, then you would
dial 201 to access channel 1 of the Sales MultiVOIP. This would ring the Key Telephone System
(KTS) at the Sales office. An attendant at the Sales office would then direct your call.
