242 Model 6757i IP Phone User Guide
Available Features Enabled by Administrators
XML Applications and Off-Hook Interaction
If enabled by your Administrator, the 6757i can be prevented from going into the off-hook/
dialing state when the handset is off-hook and the call ends. This feature is disabled by default
and must be enabled by your Administrator. The disabled 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 6757i 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 softkeys/expansion module keys
applicable to the XML application 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 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 signaling).
Contact your System Administrator for more information about this feature.
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 controls on the IP phone to adjust the
volume (increase or decrease) to your specifications.
