MOCET IP3092/IP3092L Communicator User Guide
3.3.2. Calls
A “Call” in this guide represents how many simultaneous connections can be made to a
single phone number. Each line of service in the Communicator can support up to four
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 Communicator phone is said to
support
multiple call appearances.
Note: The Commander App v1.x supports 1 Line and 2 Calls.
3.3.3. Registration
The Communicator must be configured before it can perform some functions. Although the
phone can make a peer-to-peer SIP call by dialing the other user’s IP address (i.e.,
192.168.1.10) 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 system service (DSS) as well as
showing the busy lamp field (BLF) status of system phones. These allow you to directly
dial another extension and can show you whether the other phone is 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).
3.3.4. 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
IP 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.
3.4. Configuring Your IP Phone for Service
The Communicator must be configured for the hosted SIP service or IP PBX before
operation. The phone is usually pre-configured by the administrator or hosted SIP service
provider. For an advanced or experienced user, you may refer to the Communicator
Administrator Guide for full information on how to configure all the settings of the
Communicator.
