The purpose of the Redirecting number information element is to identify to the diverted-to user the number from which diversion was invoked.
In normal calls there are CALLED NUMBER and CALLING NUMBER information elements, where the CALLING NUMBER contains the number of the user that is originating the call.
When the user is receiving a call and wants to redirect the call to another number he has to make a second call and internally connect the two calls. The second call can be done in two ways:
Redirecting call
CALLING NUMBER contains the number of ORIGINAL CALLER and add a REDIRECTING NUMBER that contains the number of the redirecting user.
The REDIRECTING NUMBER can be inserted by Abilis when performing the call forwards, the unconditional call transfers, and the third part transfers (3pTransfer), but it can also be received from a peer over a ISDN, CLUS, VO, SIP, and may be IAX interfaces.
Both situations has to be handled appropriately, with a great attention to the calling number VALIDATION which is present in all interfaces (NUM/NUMx for CLUS, NET-NUM for CTIVO, SIP/IAX-CG-NUM and CTISIP/CTIIAX table, NUM for ISDN).
For all interfaces are added the corresponding parameters:
CTIP-CF-CGO:[*,
USER]
CLUS-CF-CGO:[*,
USER]
VO-CF-CGO:[*,
USER]
SIP-CF-CGO:[*,
USER]
IAX-CF-CGO:[*,
USER]
USER: the call not include the RG
element, the call becomes a Normal
call.
*: the call include the RG (REDIRECTING
NUMBER ) element, even if empty.
The CALLING NUMBER contain the original calling number.
The REDIRECTING NUMBER contain the number assigned to the user.

To Enable/Disable support for incoming REDIRECTING NUMBER for
CLUS, SIP, IAX is needed to configure the
RG-IN:[DISABLE,
ENABLE] parameter:
DISABLE:
For CLUS:
If NUM: not equal to
"*" it is verified according to
NUMx and NUM
parameters, rewritten with NUM-IN-REWRITE
then passed to CTIR.
If NUM:* it is
passed unnmodified and NUM-IN-REWRITE
ignored.
For SIP: The incoming CALLING NUMBER is verified according
to SIP-CG-NUM parameter then passed to
CTIR.
For IAX: The incoming CALLING NUMBER is verified according
to IAX-CG-NUM parameter then passed to
CTIR.
ENABLE
Incoming call WITHOUT REDIRECTING NUMBER
Same behaviour as for DISABLE.
Incoming call WITH REDIRECTING NUMBER:
For CLUS:
The incoming CALLING NUMBER is passed unmodified to CTIR.
If NUM: not equal to
"*" the REDIRECTING NUMBER is
verified according to NUMx and
NUM parameters, rewritten with
NUM-IN-REWRITE then passed to
CTIR.
If NUM:* the
REDIRECTING NUMBER is passed unmodified and
NUM-IN-REWRITE ignored.

Interesting chapter: Section 55.4.1, “NUM and NUMx parameters for incoming calls”. |
For SIP:
The incoming CALLING NUMBER is passed unmodified to CTIR.
The incoming REDIRECTING NUMBER is verified
according to SIP-CG-NUM then passed
to CTIR.
For IAX:
The incoming CALLING NUMBER is passed unmodified to CTIR.
The incoming REDIRECTING NUMBER is verified
according to IAX-CG-NUM then passed
to CTIR.
For ISDN, thanks to the fact that in practice
NUM has been always left configured as
*, the support of RG will not be disabled, therefore
we do not need RG-IN parameter as in
CLUSTER/SIP/IAX.
ISDN NT:
Incoming call WITHOUT REDIRECTING NUMBER
The incoming CALLING NUMBER is verified against
NUM.
Incoming call WITH REDIRECTING NUMBER
The incoming CALLING NUMBER is passed unmodified to CTIR.
If NUM: not equal to
"*" the REDIRECTING NUMBER is verified
according to NUM parameter then passed to
CTIR.
If NUM:* the
REDIRECTING NUMBER is passed unmodified to CTIR.
ISDN TE:
Incoming CALLING NUMBER and REDIRECTING NUMBER are passed unmodified to CTIR.
These two parameters have been introduced in the CTIR to
manipulate the REDIRECTING NUMBER. The default for
RGI and RGO is
*.
A call originated by a call transfer may be identified because RG field isn't empty, while a normal call has RG field empty. This is used to create special routings which are effective only for call transfers.
Use the following values to intercept normal calls:
RGI:## | Missing information element |
RGI:# | Missing or Empty information element |
Set the RGI parameter to a specific value to
intercept only calls originated by call transfers.
Setting RGI:*, the rule
intercepts every kind of call (transferred or not). The following table
shows the range of RGI values:
