Types of Calls You Can Make
Depending on your system configuration, you may be able to make calls using
ISDN, IP, or V.35.
The following table lists some possible call combinations.
Placing Audio-only Calls and Adding Audio-only Sites
You may be able to use your Polycom system to place an audio-only call or add
an audio-only call to a video conference.
From... You can call... By dialing...
ISDN ISDN Phone number.
IP Phone number of the far-site gateway
and the extension (E.164 address) of the
far site.
Enter the extension after the gateway
number or wait until the gateway
prompts you for the extension.
LAN Networked and Public
Sites
Alias, E.164 address, DNS name, or IP
address.
Protected and Private
Sites
Typically, the far site's gateway number
then the number of the far-site system.
Consult with the far site about the best
method for placing the call.
ISDN Access code of the near-site gateway,
the selected speed code, and the ISDN
number of the far site.
When you call an IP system through a gateway that requires an extension (E.164
address), enter the extension in the dialing field whenever possible. Check with
your network administrator for the extension delimiter you will need to enter into the
dialing field. For example, some networks use ## to separate the extension from
the IP address.
When you include the extension, you will be given the option of saving both the
number and the extension in the directory when the call ends. If you enter the
extension after the gateway connects, then you can save only the gateway number
when the call ends.
Other audio options are available if your conference room has a Polycom system
integrated with a SoundStation VTX 1000® conference phone.
