Chapter 13 Voice Over IP (VoIP)

7.Because the IP station can have only two-operation mode (Location number), when the number of remote sites (Location numbers) is over two, there is a case that the appropriate communications may not be available. Refer to Example 2 for details.

Location number in each operation mode for each IP station:

<IP stations in Location #0: STA. 200 and 201> Remote Connection Mode: Location #1 Local Connection Mode: Location #0

<IP stations in Location #1: STA. 202 and 302> Remote Connection Mode: Location #1 Local Connection Mode: Location #0 or #2 <IP stations in Location #2: STA. 300 and 301> Remote Connection Mode: Location #1 Local Connection Mode: Location #2

Operation mode for each IP terminal:

<IP terminals in Location #0> Local Connection Mode <IP terminals in Location #1> Remote Connection Mode <IP terminals in Location #2> Local Connection Mode

Example 1: When Sta. 200 logs in Location #1

STA. 200 logs out from Location #0, and then logs in from IP terminals in Location #1. STA 200 works in Remote Connection Mode (because IP terminals in Location # 1 are assigned to Remote Connection Mode.), under the conditions of Location #1 (because STA. 200 in Remote Connection Mode is assigned to operate under the condition of Location #1.). In this case, the appropriate communication is available because the operating condition of STA. 200 matches the actual Location number (Location #1).

Example 2: When Sta. 200 logs in Location #2

STA. 200 logs out from Location #0, and then logs in from IP terminals in Location #2. STA. 200 works in Local Connection Mode (because IP terminals in Location # 2 are assigned to Locale Connection Mode.), under the conditions of Location #0 (because STA. 200 in Local Connection Mode is assigned to operate under the condition of Location #0.). In this case, the appropriate communication may not be available because the operating condition of STA. 200 (Location #0) does not match the actual Location number (Location #2).

8.Following features are not available for IP terminals at remote sites: Multiple Line Operation

Assignment of feature keys which the lamp indication and ringer is controlled by other IP terminals
