DIRECT IP CALLS

Direct IP calling allows two parties with VoIP devices (e.g. HT496 and 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 HT496or “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.

CALL HOLD

Press the “flash” button to place a caller on hold. Press the “flash” button again to release call hold.

CALL WAITING

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.

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.
