Calling from the Call HistoryYou can make a video conference call from the call history. The call history is divided into outgoing and incomingcalls. The last 30 video conference calls made and received are stored in the outgoing and incoming call history.Information such as the contact name or IP address (or host name)/SIP URI/MCU’s conference roomnumber@IP address/MCU’s SIP user name@IP address, the date and time, the duration of the call, and theresult of the call is displayed for each call on the outgoing call history screen and incoming call history screen.If the IP address/SIP URI/MCU’s conference room number@IP address of an entry in the call history is deletedfrom or edited in the contact list, the contact name in the call history entry will be replaced by the IP address/SIP URI/MCU’s conference room number@IP address.Note• In IP mode, to initiate a video conference call from a SIP URI (SIP user name@SIP domain name) ora SIP user name displayed in the call history, you must set "SIP Server" to "ON" and specify "SIPServer Address", "SIP Username", and "SIP Domain Name". Also, specify "DigestAuthentication", "Authentication ID", and "Authentication Password" as necessary (Page 105).For details, contact your network administrator.• If the other party uses the same SIP domain name as you, only the SIP user name, and not the SIPURI (SIP user name@SIP domain name) will be displayed in the call history.Outgoing Call History:• 2-party/3-party/4-party video conference calls can be made using the outgoing call history.Note• If you are using the KX-VC300, 3-party/4-party video conference calls using the outgoing call historycan only be made after purchasing an activation key card (KX-VCS301) to activate multiple-partyvideo conference calls (Page 107). For details about the activation key, contact your dealer.• When connecting to non-Panasonic video conference systems, you can make only 2-party videoconference calls using the outgoing call history.• For video conference calls made using the contact list, the contact name is displayed. For video conferencecalls made by entering the IP address/SIP URI/MCU’s conference room number@IP address directly(Page 41), that information is displayed. (That information is displayed even if a matching entry exists inthe contact list.)• If consecutive video conference calls are made to the same destination, only the latest call will appear inthe outgoing call history.Incoming Call History:• Only 2-party video conference calls can be made using the incoming call history.• If the calling party’s IP address/SIP URI/MCU’s conference room number@IP address is registered in thecontact list, the contact name is displayed. Otherwise, the IP address (or host name)/SIP URI/MCU’sconference room number@IP address/MCU’s SIP user name@IP address is displayed.• Depending on the type of MCU, a video conference call may be received from the MCU’s SIP username@IP address rather than the MCU’s conference room number@IP address. In that case, you directlycannot call the MCU’s conference room from this incoming call history.• If consecutive unanswered video conference calls are received from the same party, only the latest callwill appear in the incoming call history.• You cannot make a video conference call to a host name displayed in the incoming call history.• You may not be able to initiate video conference calls with SIP URIs (or SIP user names) in the incomingcall history for a reason such as non-compliance with the RFC. In this case, contact your networkadministrator.44 Operating Manual Document Version 2012-03Starting a Video Conference
