2.4 Call Transfer

2.4.1 Blind Transfer

Assume that call Caller A and B are in conversation. A wants to Blind Transfer B to C: 1. Caller A

presses FLASH on the analog phone to hear the dial tone. 2. Caller A dials *87 then dials caller

C’s number, and then # (or wait for 4 seconds) 3. Caller A will hear the confirm tone. Then, A can

hang up.

NOTE: “Call features enable” 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 hand 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.

2.4.2 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 3 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.
