Mediant 1000 Gateway & E-SBC | User's Manual
Table 68-60:IP Connectivity Parameters
Parameter Description
'Enable Alt Routing Tel to IP'
configure voip > gateway
routing settings > alt-
routing-tel2ip
[AltRoutingTel2IPEnable]
Enables the device to check the connectivity status of
IP destinations of configured Tel-to-IP routing rules in the
Tel-to-IP Routing table. This can then be used to trigger
alternative routing for Tel-to-IP calls if connectivity with
an IP destination is down and an alternative routing rule
has been configured.
■ [0] Disable = (Default) Disables the IP Connectivity
feature.
■ [1] Enable = Enables the IP Connectivity feature.
■ [2] Status Only = The IP Connectivity feature is
disabled, but read-only information on the QoS of the
IP destination is provided.
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 a 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) 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.
