Calling by Entering a Name or Number

To place a call by entering a name or number:
1From the Home screen select Place a Call, or start entering numbers with
the remote control to go to the Place a Call screen if it is enabled on your
system.
2In the dialing field, enter the dialing information. Depending on the
capabilities of your system and the system you are calling, the dialing
information could look like one of these examples:
—10.11.12.13 (IPv4 address—include the dots)
—1b11:22ad:333a:444b:5cc5:66d6:e777:88f8 (IPv6 address—include the
colons)
—2555 (E.164 extension for H.323 or SIP)
—stereo.polycom.com (DNS name)
—19782922854 (ISDN or phone number)
—user@domain.com (SIP)
To enter letters, press Keyboard on the remote control.
To delete a number, press Delete on the remote control.
3Enter any additional information needed for the call. The available
settings depend on the type of call and your system’s configuration. Not
all calls require these settings:
— Call Quality – Specify the call rate or call type for this call. For most
calls, choose Auto to let the system determine the best quality for the
call. For audio-only calls, you might need to set this to Phone.
— Second ISDN number – Use two numbers only when the person you
are calling instructs you to do so.
