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:
• 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.
When you place calls from call lists or directories, your phone will
automatically choose the protocol to use based on the information in the call
list or directory. When you set up a contact in your Local Contact Directory,
you can specify the protocol the contact uses to handle calls. This allows your
phone to automatically use the correct protocol when you dial the contact.
