Call hold

This function is applicable on FXS port for VoIP calls only. While in conversation, pressing the
"FLASH" button on the phone will put the remote end on hold. Pressing the "FLASH" button again
will release the previously Hold state and the bi-directional media resume.
5.2.4

Call waiting

This function is applicable on FXS port for VoIP calls only. If call waiting feature is enabled, while the
user is in a conversation, he will hear a special stutter tone if there is another incoming call. User can
press the flash button to put the current call party on hold and switch to the other call. Pressing
"FLASH" button essentially becomes toggling between two active calls.
5.2.5

Blind Transfer

This function is applicable on FXS port for VoIP calls only. Assume that call party A and B are in
conversation. A wants to Blind Transfer B to C:
1. A press "FLASH" on the analog phone to hear the dial tone.
2. Then A dials *87 then dials C's number, and then #(or wait for 4 seconds)
3. A can hang up.
NOTES: "Enable Call Feature" has to be set to YES in web configuration page. "Send flash event"
needs to be set to NO.
A can hold on to the phone and wait one of the three following behaviors:
• A quick confirmation tone (temporarily using the call waiting indication tone) follows by a
dial tone. This indicates the transfer has been successful.
• A quick busy tone followed by a restored call (On supported platforms only). This means that
B is transfered to C with no success. The busy tone is just to indicate A that the transfer has
failed.
•
Busy tone keeps playing. This means A have failed to receive the second NOTIFY from B
and decide to time out. Note: this does not indicate the transfer has been successful, nor does
it indicate the transfer has failed. When B is a client that does not support the second NOTIFY,
this will be the case. In bad network scenarios, this could also happen, although the transfer
may have been completed successfully.
