Telephone to IP/Outbound Routing Table
The Tel to IP/OutBound Routing Table is used to route incoming Tel calls to IP
addresses. This routing table associates a called / calling telephone number’s prefixes
with a destination IP address or with an FQDN (Fully Qualified Domain Name). When
a call is routed through the Mediant 8000 (Proxy is not used), the called and calling
numbers are compared to the list of prefixes on the IP Routing Table (up to 50
prefixes can be configured); Calls that match these prefixes are sent to the IP
address or IP Group. If the number dialed does not match these prefixes, the call is
not made.
The Tel to IP / Outbound Routing Table may also be used for IP-to-IP calls to perform
“outbound routing” – i.e. to determine a destination IP address or IP Group where
specific IP-to-IP calls will be sent.
When using a Proxy server, you do not need to configure the Telephone to IP Routing
Table. However, if you want to use fallback routing when communication with Proxy is
lost, or to use the 'Filter Calls to IP' and IP Security features, or to obtain different SIP
URI host names (per called number), you need to configure the IP Routing Table.
For the Telephone to IP Routing table to take precedence over a Proxy for routing
calls, In the SIP Routing Settings screen, set the
Prefer Routing Table
parameter to
Enable
. The Mediant 8000 checks the Destination IP Address field in the Telephone to
IP Routing table for a match with the outgoing call. Only if a match is not found, a
Proxy is used.
41.6.1.1
Telephone to IP/Outbound Routing Provisioning Rules
The Telephone to IP / Outbound Routing table consists of the following two parts:
Matching Rules
Destination Rules
All calls that match all or any combination of the “matching rules” are subsequently
sent to the destination IP address or IP Group, defined by the “destination rules”.
For alternative routing, additional entries of the same prefixes can be configured.
For available notations that represent multiple numbers, see 'Dialing Plan Notation' on
page
41.6.1.2
Possible Uses for Telephone to IP/Outbound Routing
Possible uses for Telephone-to-IP/Outbound routing include the following:
Proxy Fallback
– Fallback to internal routing table if there is no communication
with the Proxy.
Call Restriction
– (when Proxy is not used), reject all outgoing Tel to IP calls that
are associated with the destination IP address: 0.0.0.0. (See the SIP Protocol
Definition screen Call Security tab Secure Calls from IP parameter.)
IP Security
– When the IP Security feature is enabled (Secure Calls From IP =
Yes), the Mediant 8000 accepts only those IP to Tel calls with a source IP
address identical to one of the IP addresses entered in the Telephone to IP
Routing Table.
