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 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.
•
