Call Hold, Call Waiting, Call Transfer | Grandstream Networks HT502

Using Star Code

1.Pick up the analog phone then dial “*47”

2.Enter the target IP address.

Note: NO dial tone will be played between step 1 and 2.

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

Examples of Direct IP Calls:

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

47 or Voice Prompt with option 47, then 1921680160.

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 cannot make direct IP calls between FXS1 to FXS2 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 (3 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.
