Call Routing Table
The Call Routing service simplifies the calling procedure for Quadro users, i.e., SIP or IP-PSTN can be accomplished in the same way. With Local
Routing, each Quadro uses its routing resources set by the Quadro administrator in the call routing table. No SIP registration is needed to make
routing calls.
Defining patterns in the Local Routing Table avoids
registering Quadro at the routing management server
and gives a possibility to establish a direct connection to
the destination or to use a SIP server for call routing.
The Call Routing Table lists manually created routing
patterns with their parameters (pattern number, state,
routing settings, metric and description).

Since Call Routing Table may have multiple entries that could match to same pattern, the table will be internally rearranged according to the rules
with these consequences:
• The pattern matching best to the Best Matching Algorithm will have the higher position in the rearranged list
• If multiple patterns equally match to the Best Matching Algorithm, the pattern with the lower metric will get the higher position in the rearranged
list
• If the multiple patterns with the same metric have been matched to the Best Matching Algorithm, the pattern in the higher position in the table
will get the higher position in the rearranged list.
The pattern in the highest position of the rearranged list will be considered as the preferred one. The second and subsequent matching patterns will
be used, if the destination refused the call due to the configured Fail Reason.
The Enable/Disable functional buttons are used to enable/disable the selected route(s). Disabled routes will have no effect. Enabled routes will be
parsed when initiating routing calls. The State column in the Call Routing Table displays the current state of the routes (enabled/disabled).
Add starts the Call Routing Wizard where a new routing pattern may be defined. The Call Routing Wizard is divided into several pages. Page 1
displays the following components:
The Pattern text field requires entering the routing pattern identification. To make a specified call, the appropriate routing pattern should be dialed.
Wildcard symbols are allowed here (see chapter
Entering a SIP Addresses correctly). '[' , ']' , ',', '-', ‘{‘, ‘}’ are used to define a range or a quantity of
numbers, ‘!’ symbol is used for exclusion (“!5a” inserted in Pattern field means all patterns except those equal to 5a). For example, 2{13-17, ww, a-c}
means that the dialed number may be 213, 214, 215, 216, or 217, 2ww, 2a, 2b and 2c to match the specified pattern; in the case of 2[3,7], the dialed
number may be 23 or 27 to match the specified pattern.
Please Note: Patterns starting with the “\*” symbols cannot be used for local calls. The reason is that all local patterns starting with “\*” will be
considered as feature codes and will not be parsed through the Call Routing table.
Number of Discarded Symbols (NDS) requires the number of
symbols that should be discarded from the beginning of the
routing pattern. The field should be empty if digits do not need to
be discarded. Only numeric values are allowed for this field,
otherwise the error message “Error: Number of Discarded
Symbols is incorrect - digits allowed only” will appear.
Prefix requires entering the symbols (letters, digits and any
characters supported in the SIP username) that will be placed in
front of the routing pattern instead of the discarded digits.
Suffix requires entering the symbols (letters, digits and any
characters supported in the SIP username) that will be placed in
the end of the routing pattern. For example, if the routing
Pattern is 12345, the Number of Discarded Symbols is two,
and the Prefix is 909 and Suffix is 0a, the final phone number
will be 9093450a.
