9. Your are brought back to the
Call Routing Config
sub-menu. You can see the
Hunt Group
you have just created
in the
Hunt
section.
You can also see a yellow
Yes
warning you that the configuration has been modified but not applied (i.e., the
Call
Routing Status
differs from the
Call Routing Config
). The
Call Routing Config
sub-menu is a working area where
you build up a Call Router configuration. While you work in this area, the configured parameters are saved but not
applied (i.e., they are not used to process incoming calls). The yellow
Yes
flag warns you that the configuration has
been modified but is not applied. You will apply the configuration later when it is complete.
Mappings
The purpose of this subsection is to configure Mappings in the Mediatrix 3000 DG, so they can be referred to later when
creating routes that need to add/remove a prefix from called phone numbers.
In the current scenario, when calls are routed from the PSTN to SIP, the prefix
030
(area code) needs to be removed from
the called number. As well, when calls are routed from SIP to the PSTN, the prefix
030
needs to be added to the called
phone number. You will use Mappings to perform these transformations on the called phone number.
The Mappings are described by two entities in the Mediatrix 3000 DG: Mapping Types and Mapping Expressions. This
allows to create virtual M
apping “tables”, where a Mapping Type defines the criteria a call must fulfill to enter the table, and
the associated Mapping Expressions describe specific transformation rows in the table.
The most basic Mapping table consists in one Mapping Type and one associated Mapping Expression. In the current
scenario, you will create two basic Mapping tables.
1. Locate the
Mapping Type
section.
2. Click the
button at the bottom right of the
Mapping Type
section. The following window appears.
To create a Mapping Type that applies to incoming calls from the PSTN and alters the called E.164 phone number,
proceed as follows:
3. Set the
Name
field to
From_PSTN
.
4. Set the
Criteria
field to
Called E164
using the drop-down list.
