Menu, but is not required for the Options Key redirection feature.
• Pressing the Options Menu for redirection from the server does not interfere with normal operations of the phone (for
example, pressing the options menu when on a call does not affect the call).
• If the phone is locked, you must unlock the phone before accessing the Options Menu redirect feature. After pressing
the Options Key, the phone displays a screen that allows you to unlock the phone before continuing.
• On the 6755i, the redirection feature works after selecting the Services Menu. To display the original Options Menu,
press and hold the Options key.

XML Applications and Off-Hook Interaction
If enabled by your Administrator, the 6755i can be prevented from going into the off-hook/dialing state when the hand-
set is off-hook and the call ends. This feature is disabled by default and must be enabled by your Administrator. The disa-
bled behavior is as follows:
You are in a call using the handset and the phone displays an XML application. The far-end terminates the call, and a new
XML application gets pushed/pulled onto the display. Since the handset is off-hook and in idle mode, the "offhook idle
timer" starts. When this timer expires, the phone applies dial tone and moves to the off-hook/dialing state, which then
destroys the XML application that was being displayed.
Contact your System Administrator for more information about this feature.
XML Override for a Locked Phone
The 6755i has a feature that allows a locked phone to be overridden when an XML application is sent to the phone. This
feature also allows you to still use programmable keys/softkeys/expansion module keys applicable to the XML applica-
tion even though the phone is locked. However, any keys NOT associated with the XML application cannot be used when
the phone is locked.
Also, XML Get Requests override the locked feature on the phone so that any softkey or programmable key pressed by
the user that initiates a Get Request, continues to get sent.
Only a System Administrator can configure the feature of "XML override for a locked phone:":
RTP Recording and Simultaneous Playing
The IP Phones now allow for Real-Time Transport Protocol (RTP) recording and simultaneous playing of an audio file via
XML commands created by your Administrator. The RTP and multicast RTP commands allow the phone to send/receive
an RTP stream to/from given multicast/unicast addresses (without involving SIP signalling).
Contact your System Administrator for more information about this feature.
“Hold” Feature Enhancement (for Broadsoft Servers)
The Hold feature allows you to put an active call on “hold,” then retrieve the call later. This enhancement is intended for IP
phones operating with servers that support RFC3264 (for example, Broadsoft). If a server does not support RFC3264,
then the IP phones do not use RFC3264 functionality.
Notes:
1. When an RTP stream is being sent with RTP recording and simultaneous playing (mix), the IP Phone LCD displays an
icon with an ‘m’ on top to indicate that a mixed RTP stream is being sent.
2 .When RTP stream is being received with RTP recording and simultaneous playing (mix), you can use the volume con-
trols on the IP phone to adjust the volume (increase or decrease) to your specifications.
