IP Line Description, Installation and Maintenance
3Under Voice LAN (TLAN) configuration:
a. Signaling port: The default value is 5000. The range is 1024 to
65535. The TLAN 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 QoS for 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. The TLAN Voice port range is
1024 to 65535. The default Voice ports are 5200 – 5295.
4Click the Add button to the right of Routes if entries must be made to the
card routing table. The Routes information expands.
See Figure 93 on page 390.
CAUTION
Do not set the Voice port to a value that is already used
for signaling (4100, 5000, 5100, 7300).
The Voice port defines the first port in a range spanning
the gateway channels on the card; this means a Voice
port value of 5200 reserves the following:
• ports 5200 – 5263 on the Media Card 32-port line
card
• ports 5200 – 5215 on the Media Card 8-port line card
• and 5200 – 5247 on the ITG-P 24-port line card.
If this value is changed from the default, verify that the
selected Voice port value does not intrude into one of the
reserved Signaling port values.
