3.4.5.4.2 Tel to IP Routing Table
The 'Tel to IP Routing' page provides a table for routing Tel calls to IP addresses. This
routing table associates a called / calling telephone number's prefixes with a destination IP
address or with a Fully Qualified Domain Name (FQDN). When a call is routed by the
device (i.e., a Proxy server isn't used), the called and calling numbers are compared to the
list of prefixes in this table. Calls that match these prefixes are sent to the corresponding IP
address. If the number dialed does not match these prefixes, the call is not made. You can
add up to 50 Tel-to-IP routing rules in the table.
When using a Proxy server, you do not need to configure this table, unless you require one
of the following:
Fallback routing when communication with Proxy servers is lost.
Implement the 'Filter Calls to IP' and 'IP Security' features.
Obtain different SIP URI host names (per called number).
Assign IP profiles.
SIP User's Manual
Determines the event(s) reason for triggering Alternative Routing.
[0] None = Alternative routing is not used.
[1] Connectivity = Alternative routing is performed if ping to initial
destination fails.
[2] QoS = Alternative routing is performed if poor QoS is detected.
[3] Both = Alternative routing is performed if either ping to initial
destination fails, poor Quality of Service is detected, or DNS host name
is not resolved (default).
Notes:
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. For information on the Alternative Routing
feature, refer to ''Configuring Alternative Routing (Based on
Connectivity and QoS)'' on page 415.
To receive quality information (displayed in the 'Quality Status' and
'Quality Info.' fields in ''IP Connectivity'' on page 289) per destination,
this parameter must be set to 2 or 3.
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.
Packet loss percentage at which the IP connection is considered a failure
and Alternative Routing mechanism is activated.
The range is 1 to 20%. The default value is 20%.
Transmission delay (in msec) at which the IP connection is considered a
failure and Alternative Routing mechanism is activated.
The range is 100 to 1000. The default value is 250.
