2. The default Starting RTP port is 6000. If required, enter a different port number ranging from
1024 to 65535.
Each TalkSwitch unit with four VoIP lines requires four RTP ports. The RTP ports are evenly
numbered from the starting port as follows:
• TalkSwitch unit 1 — 6000 to 6006
• TalkSwitch unit 2 — 6010 to 6016
• TalkSwitch unit 3 — 6020 to 6026
• TalkSwitch unit 4 — 6030 to 6036
Each TalkSwitch unit with eight VoIP lines requires eight RTP ports. The RTP ports are evenly
numbered from the starting port as follows:
• TalkSwitch unit 1 — 6100 to 6114
• TalkSwitch unit 2 — 6200 to 6214
• TalkSwitch unit 3 — 6300 to 6314
• TalkSwitch unit 4 — 6400 to 6414
These are the RTP ports the TalkSwitch system listens to for audio. If these are not opened
correctly, users will not hear their callers.

Clock Preferences

The Clock Preferences command allows you to have the TalkSwitch system get the time and
date (but not the year or time zone) from caller ID. This allows the system to refresh the clock
automatically. It is beneficial if your area has frequent power outages that cause the system
time to become inaccurate. However it is not recommended if you have more than one telephone
service (e.g. regular telephone and VoIP) because the telephone services could have
conflicting times.
1. Choose Options > Clock Preferences. The Caller ID / Time Set Options window appears.
2. Select the Obtain system time from caller ID check box to have the TalkSwitch unit update
its internal clock using the timestamp within caller ID. If it is not selected, set the time
using the TalkSwitch Date and Time Properties window. See System time on page 31.

Internal Calls

The Internal Calls command allows you to set whether intercom calls use the call cascade of the
dialed extension if the extension is busy, unanswered or in do not disturb mode. An intercom
call is a call from a local extension to another local extension, remote extension or ring group.
1. Choose Options > Internal Calls. The Intercom Calls Options window appears.
