outgoing call.
 A silence period of about three seconds occurs after pressing the ‘Flash’ key during a conversation
(normally, the user presses ‘Flash’ + ’1’, ‘Flash’ + ’2’, or ‘Flash’ + ’3’). This limitation does not occur
when in ”Flash only” key sequence mode.
 QoS traffic shaping: Enabling ‘TCP Serialization’ may cause problems viewing real-time video
streams on a PC that is connected to the device.
 Caller ID Type II audio indication is sometimes heard by both the calling and the called parties. The
remote side doesn't hear the FSK; only an RFC 2833 DTMF tone.
 To ensure that the OPTIONS Keep-Alive feature is fully functional, the remote side must send any
message, including the “501 Not implemented” SIP message.
 Enabling or disabling the Periodic Checking of Configuration File feature requires a device reboot.
 A SIP NOTIFY message with a “check-sync” event with a message body causes a device restart
even if there are ongoing conversation calls.
