Firmware 1.0.4.2 Last Updated: 06/2011

Destination ports can be specified by using “*” (encoding for “:”) followed by the port number.

Examples:

a) If the target IP address is 192.168.0.160, the dialing convention is

*47 or Voice Prompt with option 47, then 192*168*0*160.

followed by pressing the “#” key if it is configured as a send key or wait 4 seconds. In this case,

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, then the dialing convention would be:

*47 or Voice Prompt with option 47, then 192*168*0*160*5062 followed by pressing the “#” key

if it is configured as a send key or wait for 4 seconds.

NOTE: When completing direct IP call, the “Use Random Port” should set to “NO”. You can not make

direct IP calls between FXS ports since they are using same IP.

CALL HOLD

Place a call on hold by pressing the “flash” button on the analog phone (if the phone has that button).

Press the “flash” button again to release the previously held Caller and resume conversation. If no “flash”

button is available, use “hook flash” (toggle on-off hook quickly). You may drop a call using hook flash.

CALL WAITING

Call waiting tone (2 short beeps) indicates an incoming call, if the call waiting feature is enabled. 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.

CALL TRANSFER

BLIND TRANSFER

Assume that call Caller A and B are in conversation. A wants to Blind Transfer B to C:

3. Caller A presses FLASH on the analog phone to hear the dial tone.

4. Caller A dials *87 then dials caller C’s number, and then # (or wait for 4 seconds).

5. Caller A will hear the confirm tone. Then, A can hang up.

NOTE: “Enable Call Feature” must be set to “Yes” in web configuration page.

Caller A can place a call on hold and wait for one of three situations:

1. A quick confirmation tone (similar to call waiting tone) followed by a dial tone. This indicates the

transfer is successful (transferee has received a 200 OK from transfer target). At this point,

Caller A can either hang up or make another call.

2. A quick busy tone followed by a restored call (on supported platforms only). This means the

transferee has received a 4xx response for the INVITE and we will try to recover the call. The

busy tone is just to indicate to the transferor that the transfer has failed.

3. Continuous busy tone. The phone 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.

ATTENDED

TRANSFER

Assume that Caller A and B are in conversation. Caller A wants to Attend Transfer B to C:

1. Caller A presses FLASH on the analog phone for dial tone.
