Making A Call - Aastra S850i Administrator's Manual

If further settings are required to connect the S850i to your SIP Call Server (e.g. a proxy server) please visit the S850i Web
Interface. You get to this interface by entering the IP address of the S850i into the web browser of your choice. After you
entered the password (2222, unless you changed it in the Handset/Dialer), you can find the SIP settings under the Admin-
istrator tab on the top right. You will find the different SIP settings under SIP Registration, SIP Configuration, Transport, and
Media. You have to press Save on every page where you changed an entry to save these changes. If you do not press Save,
the changes will be lost when you leave that page. Restart the phone once you are finished with your changes.
Once the S850i is registered with the SIP Call Server, it will display the ID in the screen and is ready to make and receive
phone calls.

Making a Call

To make a conference call, take at least one of the Microphones out of the Charger Tray, and take the Handset/Dialer out of
the Charger Tray. You can remove all Microphones and the Speaker if you wish, but this is not required. Use the Hand-
set/Dialer to enter the number you want to call, including any leading digits your VoIP telephone switch might require.
The Speaker and any Microphone that is not in the Charger Tray will be active during the call. To finish a conference call,
press the red hang-up button on the Handset/Dialer.
Note:
It is also possible to have a conference call with the Microphones in the Charger Tray. However, due to the proximity of
Microphone and Speaker at that time, audio quality might be impacted. The maximum volume of the Speaker is lim-
ited while the Microphones are in the Charger Tray. Microphones that are placed into the Charger Tray are switched off.
To use Microphones in the Charger Tray for phone calls they first have to be switched on. You do this by pressing the
button on the Microphone while it is in the Charger Tray. The Microphone will start in a muted state. Once it starts blink-
ing red, unmute it by pressing the mute button once again. Microphones in the Charger Tray never transmit audio to
the AUX OUT connector. If any Microphone is active outside of the Charger Tray, Microphones in the Charger Tray can-
not be activated (unmuted) for the call unless removed.
To make a call using the Handset/Dialer, make sure that all Microphones are in the Charger Tray before starting to dial the
number. At this point, only the Handset/Dialer will be used for the call. To end the call, press the red hang-up button on the
Handset/Dialer.
At any time during a call you can toggle between Handset and Speaker mode using the buttons on the Handset/Dialer.
To answer a call using the conference phone, simply remove one or more Microphones from the Charger Tray when the
Speaker rings. If a Microphone is already out of the Charger Tray when an incoming call comes in, pressing the button on
the Microphone will answer the call in conference phone mode. You can also use the Handset/Dialer to answer the call by
pressing the green call button on the Handset/Dialer. If all Microphones are in the Charger Tray at this time, the call will be
answered using the Speaker Mode. If at least one Microphone is switched on and not in the Charger Tray, this will answer
the call in Speaker mode.
