Blind Transfer, Attended Transfer | Grandstream Networks HT-502

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.

2.Caller A then dials Caller C’s number followed by # (or wait for 4 seconds).

3.If Caller C answers the call, Caller A and Caller C are in conversation. Then A can hang up to complete transfer.

4.If Caller C does not answer the call, Caller A can press “flash” to resume call with Caller B.

NOTE: When Attended Transfer fails and A hangs up, the HT-502 will ring back user A to remind A that B is still on the call. A can pick up the phone to resume conversation with B.

3-WAY CONFERENCING

The HT-502 supports Bellcore style 3-way Conference.

Instructions for 3-way conference:

3.If C answers the call, then A presses FLASH to bring B, C in the conference.
