Issue 1.0
Manual mode – when the phone boots up it will prompt the user to enter a user id and password
before logging in. If a user id and password is set in the SIP User settings of the phone, like
Automatic mode, the phone will not prompt for login. This gives the ability to have some phones
come up automatically and some phones prompt for login. In manual mode, the phones that do not
have a user id and password set in the phone will be prompted to log in.
Registration Override
When Manual mode is used, Registration Override can be used. Registration Override allows a user to
login at one phone, and later login at another phone and keep the same extension number. This is useful
in the case where an office user has an IP multiline terminal at work and at home or a Softphone they use
on the road. They log in at work to use the office terminal, and when they get home or are on the road they
login the home terminal or Softphone. When this happens the office terminal is logged out and they have
the same extension number at home or on the road.
Conditions
The voice quality of VoIP is dependent on variables such as available bandwidth, network
latency and Quality of Service (QoS) initiatives, all of which are controlled by the network and
internet service providers. Because these variables are not in NEC control, it cannot
guarantee the performance of the user's IP-based remote voice solution. Therefore, NEC
recommends connecting VoIP equipment through a local area network using a Private IP
address.
IP Multiline Stations must register with the IP address of the IPLA. The IP Multiline stations
registering via a URL is not supported.
If an internal paging group has only IP Multiline Stations, mutlicast is used for the page. IP
Multiline terminals must have a gateway programmed to accomplish a multicast
transmission. When an actual gateway device does not exist on the network, a dummy
gateway address on the same subnet must be defined. If the paging group has any TDM
stations or an external speaker, multicast is not used and the gateway is not required.
