hold, the corresponding Line Key LED blinks slowly in red. To resume a holding call, press the
corresponding Line Key.
Pressing the Hold key always apply to all the currently connected calls, but it does not affect calls in other
states. Resume operation only applies to the current call appearance. These combinations will allow very
flexible call handling.
Note: When the phone is hosting a 3-way conference, two call appearances are in the connected state.
Pressing Hold key will hold both calls. Then the user can press a Line Key to bring back one of parties to
the connected state.
Call-Waiting
Call-waiting here refers to the case of a new incoming call while there is another active call. The SPA-841
does not support multiple calls on the same Line key. The corresponding Line key blinks quickly in red on
any incoming call. If there is no other active calls, the SPA-841 will ring with either the default ring of that
extension or the distinctive ring associated with the caller. If there is another active call, however, the
SPA-841 will not ring the phone, but plays the call-waiting tone to alert the user.
The SPA-841 supports multiple call-waiting. In fact, all 4 call appearances can ring at the same time.
3-Way Conference
There are two (2) ways to start a 3-way conference on the SPA-841.
•
While the user is in a connected call with one or more free call appearances available, SK(conf) will
appear. Pressing this soft key will hold the active call and start new dial tone on the next available call
appearance. You then dial the 3
rd
party that you want to conference with. When the 3
rd
party rings or
answers, the user presses SK(conf) again to start the conference.
•
While the user is on a connected or proceeding call with one or more call appearances on hold or
ringing, SK(confLx) will appear. Pressing this soft key will hold the active call and brings up a screen
to prompt to user to press one of the holding or ringing call Line key whom he wants to conference
with. If there is one other holding or ringing call, pressing SK(confLx) will start the conference
immediately without the need to press another Line key.
Once the conference starts, the SPA-841 plays a special brief tone to all parties to indicate that all 3
parties are now online. The user can terminate the call at any time by hanging up the call. Alternatively
the user can drop out of the conference by pressing SK(join) to let the other 2 parties to continue with the
conference (this is implemented as a call transfer; so it might not work if the other 2 parties are hosted on
different service providers).
Note: If the extension is configured with an external Conference Bridge URL, then conference is not
limited to 3-way; it can be as many parties as the conference bridge can handle. Two restrictions apply
when using an external conference bridge: a)The conference can only be completed when the 3
rd
party
has answered (not just ringing) using SK(conf), and b)You can only bring a holding call into the
conference using SK(confLx), but not a ringing call.
Attended Call Transfer
There are 2 ways:
