You can configure the following parameters in the Conditions section when you create or modify a route:
Note: A route can only be matched if the three condition parts (called number, calling number, and redirect
number) match their call address counterpart in any of the lines. Empty condition entries always match, i.e., a
line with the three condition parts left empty will always apply, thus working as a default route.
Address Manipulation
You can configure the following parameter in the Address Manipulation section when you create or modify a
route:
Security Profiles
For authentication and data encryption for TLS, certificates need to be installed on the computer with Diva
SIPcontrol and on remote computers. When a secure domain is opened, the server and client authenticate each
other with a so called "SSL handshake". With this handshake, the identity of a user is certified and the user can
be trusted. All necessary certificates are provided by a Certificate Authority (CA), and they are issued for one
domain name.
For test purposes or internal usage, you can also create and sign your own self-signed certificate, e.g., with one
of the many tools available on the internet. Search for "self-signed certificate" and you will find a list of possible
tools. But you need to be aware that self-signed certificates do not provide the same security as CA-signed
certificates. Also, many web browsers check if the certificate is signed by a CA, and, if it is not, a warning message
will appear asking whether the user really wants to trust that web site, which can make the user feel insecure.
Certificate files can be generated in different formats, e.g., .pem, .der, .cer, or .pfx. All files need to be in PEM
format (base64 encoded), in order to be used by Diva SIPcontrol. For more information about secure connections
and certificates, see Data Security Overview
on page 61.
A default certificate is provided with the software, but for security reasons, you should install your own web
server certificate.
Called number: If the route is supposed to be valid only for specific calls, enter the called party number to which
the route should apply. Diva SIPcontrol compares the current called party number against the
called number entered here. If they do not match, Diva SIPcontrol verifies the next route until it
finds a match.
Calling number: If the route is supposed to be valid only for specific calls, enter the calling party number to which
the route should apply. Diva SIPcontrol compares the current calling party number against the
calling number entered here. If they do not match, Diva SIPcontrol verifies the next route until it
finds a match.
Redirect number: If the route is supposed to be valid only for specific calls, enter the redirect number to which the
route should apply. Diva SIPcontrol compares the current redirect number against the redirect
number entered here. If they do not match, Diva SIPcontrol verifies the next route until it finds a
match.
Address Map: If a route matches, the address manipulation setting allows you to modify the call addresses
according to your needs. For example, if calls with the called party number starting with "9" should
be directed to a specific peer, it might be desirable to remove this digit. This can be done with a
configured address map. You need to configure the address map as described under Address Maps
on page 53 before you can select it here.
