---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
configure voip > gateway manipulation settings > map-ip-to-pstn-refer-to [ManipulateIP2PSTNReferTo] |
Enables the manipulation of the called party (destination) number according to the SIP Refer-To header received by the device for TDM (PSTN) blind transfer. The number in the SIP Refer-To header is manipulated for all types of blind transfers to the PSTN (TBCT, ECT, RLT, and QSIG ).
During the blind transfer, the device initiates a new call to the PSTN and the destination number of this call can be manipulated if the parameter is enabled. When enabled, the manipulation is done as follows:
This source number can also be used as the value for the 'Source Phone Pattern' field in the Destination Phone Number Manipulation for IP-to-Tel Calls table. The local IP address is used as the value for the 'Source IP Address' field. Note:

|||||||||||||||||||||||||||||||||
'Tel2IP Default Redirect Reason' configure voip > gateway manipulation settings > tel-to-ip-dflt-redir-rsn [Tel2IPDefaultRedirectReason] |
Determines the default redirect reason for Tel-to-IP calls when no redirect reason (or “unknown”) exists in the received Q931 ISDN Setup message. The device includes this default redirect reason in the SIP History-Info header of the outgoing INVITE. If a redirect reason exists in the received Setup message, the parameter is ignored and the device sends the INVITE message with the reason according to the received Setup message. If the parameter is not configured (-1), the outgoing INVITE is sent with the redirect reason as received in the Setup message (if none or “unknown” reason, then without a reason).

'Add Trunk ID as Prefix' configure voip > gateway routing settings > trk-id-as-prefix [AddPortAsPrefix] |
Defines if the
If enabled, the device adds the following prefix to the called phone number: slot number (a single digit in the range of 1 to 6) and port number/Trunk ID (single digit in the range 1 to This option can be used to define various routing rules. |
|||||||||||||||||||||||||||||||||
'Add Trunk Group ID as Prefix to Source' trkgrpid-pref2source [AddTrunkGroupAsPrefixToSource] |
Enables the device to add the Trunk ID (from where the call originated) as the prefix to the calling number (i.e. source number).
|
|||||||||||||||||||||||||||||||||
'Replace Empty Destination with B-channel Phone Number' configure voip > gateway routing settings > empty-dst-w-bch-nb [ReplaceEmptyDstWithPortNumber] |
