IRECT ALLS
Direct IP calling allows two parties with VoIP devices (e.g. a HT–286and another VoIP Device), to talk to
each other in an ad hoc fashion without a SIP proxy. Direct IP calls are possible if:
a) Both VoIP devices use a public IP address; or
b) Both VoIP devices are on the same LAN using private IP addresses, or
c) Both VoIP devices can be connected through a router using public or private IP addresses (with
necessary port forwarding or DMZ).
To make a Direct IP Call, use either the handset or the speakerphone. Access the IVR using "***", the
button on the HT–286or "47". After dial tone, enter a 12-digit target IP address to place a call.
Destination ports can be specified by using "*4" (encoding for ":") followed by the port number.
Examples:
a) If the target IP address is 192.168.0.160, enter the 12 digit IP address (e.g. 1921680160) after
the voice prompt followed by the "#" key or wait for 4 seconds. The default destination port 5060
is used if no port is specified.
b) If the target IP address/port is 192.168.1.20:5062, enter the 12 digit IP address + *45062 (e.g.
1921680160*45062) after the voice prompt followed by the "#" key or wait for 4 seconds.

Press the "flash" button (or hook flash on older models) to place a caller on hold. Press the "flash" button
again to release call hold.
C W
ALL AITING
If call waiting feature is enabled, call waiting tone (3 short beeps) indicates an incoming call. Toggle
between incoming call and current call by pressing the "flash" button. First call is placed on hold. Press
the "flash" button to toggle between two active calls.
C T
ALL RANSFER
The HT–286 supports both blind and attended transfer:
1. Blind Transfer: Press "flash" button (or hook flash on older models), dial *87, then dial the
number to transfer call and press the "#" key (or wait 4 seconds) to complete transfer of active
call.
Expected outcomes:
a) A quick confirmation tone (call waiting tone) followed by a dial tone. This indicates the transfer is
successful. Hang up or place another call.
b) A quick busy tone followed by a restored call (on supported platforms only). The busy tone
indicates the transfer failed.
c) Continuous busy tone. The phone call has timed out. Note: continuous busy tone does not
indicate the transfer has been successful, nor does it indicate the transfer has failed. It often
means there was a failure to receive second NOTIFY – check firmware for most recent release.
NOTE: "Enable Call Feature" must be set to "Yes" in web configuration page.
