MP-1xx H.323 User’s Manual 5. Configuring the MP-1xx
Version 4.4 73 March 2005
Table 5-11: Routing Tables, General Parameters (continues on pages 72 to 73)
Parameter Description
IP to Tel Remove Routing
Table Prefix
[RemovePrefix]
No [0] = Don't remove prefix (default)
Yes [1] = Remove the prefix (defined in the IP to Hunt Group Routing table)
from a telephone number for an IPTel call, before forwarding it to Tel.
For example:
To route an incoming IPTel Call with destination number 21100, the IP to
Hunt Group Routing table is scanned for a matching prefix. If such prefix is
found, 21 for instance, then before the call is routed to the corresponding hunt
group the prefix (21) is removed from the original number, so that only 100 is
left.
Note 1: Applicable only if number manipulation is performed after call routing
for IPTel calls (refer to ‘IP to Tel Routing Mode’ parameter).
Note 2: Similar operation (of removing the prefix) is also achieved by using the
usual number manipulation rules.
Enable Alt Routing Tel to IP
[AltRoutingTel2IPEnable]
No [0] = Disable the Alternative Routing feature (default).
Yes [1] = Enable the Alternative Routing feature.
Status Only [2] = The Alternative Routing feature is disabled. A read only information
on the quality of service of the destination IP addresses is provided.
For information on the Alternative Routing feature refer to Section
8.4 on page 154.
Alt Routing Tel to IP Mode
[AltRoutingTel2IPMode]
None [0] = Alternative routing is not used.
Conn [1] = Alternative routing is performed if ping to initial destination failed.
QoS [2] = Alternative routing is performed if poor quality of service was detected.
Both [3] = Alternative routing is performed if, either ping to initial destination failed, or
poor quality of service was detected, or DNS host name is not resolved (default).
Note: Quality of Service (QoS) is quantified according to delay and packet loss,
calculated according to previous calls. Qos statistics are reset if no new data is received
for two minutes.
For information on the Alternative Routing feature refer to Section
8.4 on page 154.
Max Allowed Packet Loss for
Alt Routing [%]
[IPConnQoSMaxAllowedPL]
Packet loss percentage at which the IP connection is considered a failure.
The range is 1% to 20%. The default value is 20%.
Max Allowed Delay for Alt
Routing [msec]
[IPConnQoSMaxAllowedDel
ay]
Transmission delay (in msec) at which the IP connection is considered a failure.
The range is 100 to 1000. The default value is 250 msec.
