Version 7.2 1219 Mediant 1000B Gateway & E-SBC
User's Manual 65. Configuration Parameters Reference
Parameter Description
Note: If the parameter is enabled, the Busy Out feature (see
EnableBusyOut parameter) does not function with the Proxy Set
keep-alive mechanism. To use the Busy Out feature with the
Proxy Set keep-alive mechanism (for IP Groups), disable the
parameter.
Alt Routing Tel to IP Mode
configure voip > gateway routing
settings > alt-rte-tel2ip-mode
[AltRoutingTel2IPMode]
Determines the IP Connectivity event(s) reason for triggering
Alternative Routing.
 [0] None = Alternative routing is not used.
 [1] Connectivity = Alternative routing is performed if SIP
OPTIONS message to the initial destination fails (determined
according to the AltRoutingTel2IPConnMethod parameter).
 [2] QoS = Alternative routing is performed if poor QoS is
detected.
 [3] Both = (Default) Alternative routing is performed if either
SIP OPTIONS to initial destination fails, poor QoS is detected,
or the DNS host name is not resolved.
Note:
 QoS is quantified according to delay and packet loss
calculated according to previous calls. QoS statistics are reset
if no new data is received within two minutes.
 To receive quality information (displayed in the 'Quality Status'
and 'Quality Info.' fields in ''Viewing IP Connectivity'' on page
899) per destination, the parameter must be set to 2 or 3.
Alt Routing Tel to IP Connectivity
Method
configure voip > gateway routing
settings > alt-rte-tel2ip-method
[AltRoutingTel2IPConnMethod]
Determines the method used by the device for periodically
querying the connectivity status of a destination IP address.
 [0] ICMP Ping = (Default) Internet Control Message Protocol
(ICMP) ping messages.
 [1] SIP OPTIONS = The remote destination is considered
offline if the latest OPTIONS transaction timed out. Any
response to an OPTIONS request, even if indicating an error,
brings the connectivity status to online.
Note: ICMP Ping is currently not supported for the IP Connectivity
feature.
Alt Routing Tel to IP Keep Alive
Time
configure voip > gateway routing
settings > alt-rte-tel2ip-keep-alive
[AltRoutingTel2IPKeepAliveTime]
Defines the time interval (in seconds) between SIP OPTIONS
Keep-Alive messages used for the IP Connectivity application.
The valid range is 5 to 2,000,000. The default is 60.
Max Allowed Packet Loss for Alt
Routing [%]
configure voip > gateway routing
settings > mx-pkt-loss-4-alt-rte
[IPConnQoSMaxAllowedPL]
Defines the packet loss (in percentage) at which the IP connection
is considered a failure and Alternative Routing mechanism is
activated.
The default is 20%.
Max Allowed Delay for Alt
Routing
configure voip > gateway routing
settings > mx-all-dly-4-alt-rte
[IPConnQoSMaxAllowedDelay]
Defines the transmission delay (in msec) at which the IP
connection is considered a failure and the Alternative Routing
mechanism is activated.
The range is 100 to 10,000. The default is 250.
