MOCET IP3022 SOHO IP Deskphone User Guide
A “Call” in this guide represents how many simultaneous connections can be made to a
single phone number. Each line of service in the phone can support two calls
simultaneously. This allows the user to place one caller on hold and talk to the other
person in another call on the same Line. Therefore, the phone is said to support multiple
call appearances.
3.1.3. Registration
The phone must be configured before it can perform some basic functions. Although the
phone can make a peer-to-peer SIP call by dialing the other user’s IP address (i.e.,
192.168.0.12) directly on the keypad, this is inconvenient and it is hard to remember all the
IP addresses of phones on the system. This is why a hosted SIP server or local IP PBX
implements a Registrar service, which allows the connected phones to find and dial each
other more easily by extension numbers or names instead of IP addresses.
In addition, the hosted SIP server or IP PBX helps keep track of active phones, their IP
addresses for routing calls, as well as keeping track of which phones are busy or idle.
Most hosted SIP services and IP PBXs support Direct Station Select (DSS) as well as
showing the Busy Lamp Field (BLF) status of phones. These allow you to directly dial
another extension and can show you whether the selected phone is ringing or on a call or
not.
Usually, the hosted SIP service or IP PBX will also use the Registrar service to send
messages to your phone to alert you that you have voicemail. This is called message
waiting indication (MWI).
3.1.4. Caller ID
When you receive a call, the caller's phone number is shown on the screen, if the caller
has not chosen to hide his number and if the network supports the Caller ID feature. The
phone can display both the Caller ID (CLID) and the Caller Name (CNAM) of the caller if it
is available. Not all services and servers support CLID and CNAM. For more information
about this topic, please contact your service provider or system administrator.
3.2. Installing Your IP Phone
Before placing the phone into operation, either you or your administrator or Service
Provider has to install the phone on your network. Please contact your administrator or
Service Provider for more details.
