Calling Using the H.323 Protocol
Note: Calling Using H.323 Protocol is an Optional Feature
Handling calls that use the H.323 protocol is an optional feature that your system administrator
enables. Your system may not support it or have an H.323 license. For more information, contact
your system administrator.
If your phone supports the H.323 protocol, be aware of the following limitations:
» You cannot forward or transfer H.323 calls.
» You cannot set up forwarding for lines that just use the H.323 protocol.
» You cannot set up shared lines for lines that use the H.323 protocol.
You cannot place a call by just entering an H.323 name. To place a call using an H.323 name,
»
use URL-dialing mode and enter the following format for the URL:
<H.323 name>@<server name>
For example: VVX101@100.100.100.100
Your system administrator can set up your phone so that it can handle calls that use either the SIP or
H.323 protocol, or both protocols. Your phone may be set up so that a line can handle one or both
protocols.
If your phone can handle calls using both protocols, you may be able to choose the protocol to use before
you tap the Dial or Send soft key, or before a call is automatically placed. You may also be able to choose
to allow your phone to automatically select the protocol to use.
If your phone is set up to handle both protocols, you may be able to choose a protocol before you place a
call using one of the following methods:
 The soft key method
Soft keys display to allow you to choose the protocol. Tap the Use SIP, Use H.323, or Use Auto
soft key one or more times to toggle between Use SIP (to place a SIP call), Use H.323 (to place an
H.323 call), or Use Auto (to allow your phone to automatically select the protocol to use). The
protocol you select displays in the title bar. Your phone will use the selected protocol for all
subsequent calls, unless you select a different protocol.
 Dialog box method
A dialog box displays to allow you to choose the protocol. Tap Use SIP (to place a SIP call) or Use
H.323 (to place an H.323 call).
For dual-protocol phones, the protocol displays next to all call IDs, including the call IDs for conference
call participants and calls on hold. The following figure shows a SIP call placed to Jack Jones.
