Enum
No, Yes
Instant Defines whether the redirect
number is used instead of the
called number for incoming
ISDN calls.
Copy Destination to
Redirect Number
Enum
Do Not Copy, Copy After
Manipulation, Copy Before
Manipulation
Instant Defines whether the gateway
copies the received ISDN called
number to the outgoing SIP
Diversion header for Tel-to-IP
calls (even if a Redirecting
Number IE is not received in the
ISDN Setup message).
Therefore, the called number is
used as a redirect number. Call
redirection information is
typically used for Unified
Messaging and voice mail
services to identify the recipient
of a message.
Do Not Copy – Do not copy
the number.
Copy After Manipulation -
Copies the called number
after manipulation. The
gateway first performs Tel-to-
IP destination phone number
manipulation (i.e., on the SIP
To header), and only then
copies the manipulated
called number to the SIP
Diversion header for the Tel-
to-IP call. Therefore, with this
option the called and
redirected numbers are
identical.
Copy Before Manipulation –
Copies the called number
before manipulation. The
gateway first copies the
original called number to the
SIP Diversion header, and
then perform Tel-to-IP
destination phone number
manipulation. Therefore, this
allows you to have different
numbers for the called (i.e.,
SIP To header) and
