Page 614 of 910 IP Line administration using Element Manager
553-3001-365 Standard 4.00 August 2005
10 Under Voice LAN (TLAN) configuration:
a. Signaling port: The default value is 5000. The range is 1024 to
65535.
Note: The TLAN subnet Signaling occurs on UDP ports 7300, 4100,
5100, and 5000.
b. Voice port: Change the Voice port only as instructed by the IP
network administrator to improve Quality of Service for the
IP Phones. This field displays the range for RTP packets sent to the
IP Phones. For example, if RTP Header compression is used to
reduce voice bandwidth on narrow band WAN links, then the TLAN
voice port range needs to be set to 16384 or higher.
The exact range is provided by the system administrator. In general,
use the default value of 5200. If, however, numerous IP Phones are
working over low bandwidth WAN links using CISCO RTP header
compression, then change the voice port to a number in the range of
16384 to 32767. Coordinate this value change with the IP network
administrator.
Note: The TLAN Voice port range is 1024 to 65535. The default Voice
ports are 5200 – 5295. A check is performed to prevent the TLAN Voice
and signaling UDP ports from having the same range.
