Multiple Logon; Registration Override; System Ip Phones And Analog Trunks - NEC UNIVERGE SV9100 Features And Specifications

a user ID and password set in the phone are prompted to log in. A user can also Logoff the IP
phone to allow another user to login with their own user ID and password.
To Logoff the IP phone:
Press the Down Arrow Softkey, press the Prog Softkey, and then press the LOGOFF Softkey.

Multiple Logon

The same user name and password can be assigned to multiple extensions when using Automatic or
Manual Registration. This makes it easier on the user by only having to remember one password. For
example, if a user has an IP Multiline terminal and uses Desktop Applications with the Enhancement
bundle controlling the IP Multiline, three different ports are used in the system.

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.
Override with CTI is supported on a per station basis using Program 15-05-39 with certain restrictions.

System IP Phones and Analog Trunks

Due to the nature of analog-to-digital conversion, considerable echo may be encountered when using
Analog Trunks with IP Phones.
Due to all Analog trunks being different, padding of the Analog Trunks in Programs 81-07 and 14-01
may be necessary. Even after the pad changes are made, an echo may still be present the first few
seconds of the call while echo cancellers are learning the characteristics of the circuit on this call.
Program 90-68-01 can be used to automatically test the lines and auto assign the proper values in
Program 81-07. It is recommended to use this program whenever analog trunks are involved.
Digital (ISDN, T-1, and SIP) trunks do not experience this problem.
For best performance, it is recommended to use digital trunks when using IP phones.
Conditions
The voice quality of VoIP depends 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 under its control, NEC
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 GPZ-IPLE. 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.
