09 Display Software
Version Number of IP
Telephone
This is read-only. If any problem occurs it is useful to analyze the problem with
this version. A sample software version is DIP11NA. DIP1 represents the IP
telephone model; 1NA represents software version of the IP telephone; 1N
represents the version of updatable software and A means the version of not-
updatable software (BootROM).
Possible values:Max. 16 ASCII characters
10 SIP Terminal URI
Set the Uniform Resource Identifier of the SIP terminal. URI is to identify the IP
telephone in the system. You can use A-Z, a-z and 0-9 up to 32 characters as
the URI. It has to be unique in the system.
Possible values:Max 32 ASCII characters
11 SIP Terminal Password
Set password for terminal authentication of the SIP terminal. This password is
checked for terminal authentication when registration is performed from the SIP
terminal. You can use A-Z, a-z and 0-9 up to 64 characters. It doesn't have to be
unique in the system, and same password can be assigned to plural SIP
terminals.
12 IP Sta KeepAlive Timer
Keep-alive timer for station for full IP station.
Possible values:0 ~ 60 seconds
13 Station IP DTMF
Translation Mode
DTMF translation mode for full IP station.
Possible values:Tone (Default), Outband or Inband
Note
This parameter is not supported in CIX.
14 Secondary Audio Codec
for Full IP station
IP telephones have two built-in codecs. Select the audio codec that should be
used in this IP telephone.
The G.711codec - provides the highest voice quality but uses the most network
bandwidth (about 115kbps per IP telephone when in use).
The G.729A codec - provides less voice quality but uses the least amount of
network bandwidth (about 29kbps per IP telephone when in use).
High traffic or low speed networks may require the IP Telephones to use G729A.
Example:
If installing remote IP telephones connected to Cable or DSL lines, the upstream
rate is usually restricted and may not provide a consistent upstream bandwidth
(advertised as 128kbs but is normally less because of traffic) so the G729a
codec would probable be the best choice for this situation.
The Voice Packet Table Prog 250-07 and the VP Table's voice packet
parameters Prog 152 must be set properly for the codec assigned.
Possible values:G711, G729A (Default), None
15 Secondary Voice Packet
Index
CIX provides peer to peer connection when an IP telephone directly
communicates with another IP telephone. A negotiation method is required to
resolve differing audio codec settings on the IP telephones. When a call is
established between IP telephones, the CIX will check the assignment of
secondary audio codecs. If there is matching assignment, it will be applied. If
there is not, the user will hear reorder tone.
Possible values:1 ~ 128
