Manipulation

This section describes configuration of various manipulation processes for the Gateway
application.

Configuring Redirect Reasons

You can manipulate call redirect (diversion) reasons between IP (SIP) and Tel (ISDN). The SIP
Diversion header contains the information on the redirection of the call, including the reason (e.g.,
'reason=user-busy'). The ISDN provides the Redirect Number and the Reason for Redirection. You
can configure the following redirect manipulations:
■ Redirect Number screening indicator (e.g., User Failed) in ISDN Setup messages for IP-to-Tel
calls. Configuration is done using the [SetIp2TelRedirectScreeningInd] parameter.
■ IP-to-Tel redirect reason for IP-to-Tel calls in the ISDN message if redirect information is
received from the IP side. Configuration is done using the [SetIp2TelRedirectReason]
parameter.
■ Tel-to-IP redirect reason in SIP messages for Tel-to-IP calls if redirect information is received
from the Tel side. Configuration is done using the [SetTel2IpRedirectReason] parameter.
The section is applicable only to digital interfaces.
➢
To configure redirect reason manipulation:
1. Open the Manipulations Settings page (Setup menu > Signaling & Media tab > Gateway
folder > Manipulation > Manipulations Settings).
2. Configure the parameters as required, and then click Apply.
Configuring Source-Destination Number Manipulation
Rules
The number manipulation tables let you configure rules for manipulating source and destination
telephone numbers for IP-to-Tel and Tel-to-IP calls. Number manipulation include the following
tables:
■ Tel-to-IP calls:
● Source Phone Number Manipulation for Tel-to-IP Calls (up to 120 entries)
● Destination Phone Number Manipulation for Tel-to-IP Calls (up to 120 entries)
■ IP-to-Tel calls:
● Source Phone Number Manipulation for IP-to-Tel Calls (up to 120 entries)
● Destination Phone Number Manipulation for IP-to-Tel Calls (up to 120 entries)
Configuration of number manipulation rules includes two areas:
■ Match: Defines the matching characteristics of the incoming call (e.g., prefix of destination
number).
