Note:
 After entering the number, the phone waits for the No Key Entry Timeout (Default timeout is 4 seconds,
configurable via Web GUI) before dialing out. Press SEND key or # key to override the No
Key Entry Timeout;
 If digits have been entered after handset is off hook, the SEND key will works as SEND
instead of REDIAL;
 By default, # can be used as SEND to dial the number out. Users could disable it by setting "User # as
Dial Key" to "No" from Web GUI->Account->Call Settings;
 For Paging/Intercom, if the SIP Server/PBX supports the feature and has Paging/Intercom feature
code set up already, users do not necessarily need toggle to paging mode in the call screen. Simply
dial the feature code with extension as a normal call.
 When dial out via paging, user can see the “call-info” header contains “answer-after=0” and “the
“alert-info” header contains “info=alert-autoanswer;delay=0” in the outgoing INVITE.
MAKING CALLS USING IP ADDRESSES
Direct IP Call allows two phones to talk to each other in an ad-hoc fashion without a SIP proxy. VoIP calls
can be made between two phones if:
 Both phones have public IP addresses; or
 Both phones are on the same LAN/VPN using private or public IP addresses; or
 Both phones can be connected through a router using public or private IP addresses (with necessary
port forwarding or DMZ).
To make a direct IP call, please follow the steps below:
 Press MENU button to bring up main menu;
 Select "Direct IP Call" using the navigation arrow keys;
