5.2.5.2 Attended Transfer; 3-Way Conferencing; Pstn Pass Through/Life Line - Grandstream Networks HandyTone-486 User Manual

HandyTone-486 User Manual
• 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.
• Busy tone keeps playing. This means we have failed to receive the second NOTIFY from the
transferee and decided to time out. Note: this does not indicate the transfer has been
successful, nor does it indicate the transfer has failed. When transferee is a client that does not
support the second NOTIFY (such as our own earlier firmware), this will be the case. In bad
network scenarios, this could also happen, although the transfer may have been completed
successfully.

5.2.5.2 Attended Transfer

Assuming that call party A and B are in conversation. A wants to Attend Transfer B to C:
1. A presses "FLASH" on the analog phone (or Hook Flash for old model phones) to get a dial
tone
2. A then dial C's number followed by # (or wait for 4 seconds).
3. If C answers the call, A and C are in conversation. Then A can hang up to complete transfer.
4. If C does not answer the call, A can press "FLASH" back to talk to B.
NOTE:
• When Attended Transfer failed and A hang up, HandyTone- 486 will ring user A back again to
remind A that B is still on the call. A can pick up the phone to restore conversation with B.
