Number Manipulation Parameters

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 (CAS, 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:

Enables the use of the B-channel number as the calling number (sent in the From field of the INVITE) instead of the number received in the Q.931 Setup message, for Tel-to-IP calls.

For example, if the incoming calling party number in the Q.931 Setup message is "12345" and the B-channel number is 17, then the outgoing INVITE From header is set to "17" instead of "12345".

Note:

Enables the use of the B-channel number as the calling party number (sent in the Q.931 Setup message) instead of the number received in the From header of the INVITE, for IP-to-Tel calls.

For example, if the incoming INVITE From header contains "12345" and the destined B-channel number is 17, then the outgoing calling party number in the Q.931 Setup message is set to "17" instead of "12345".

Note:

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).

Defines the value of the Redirect Number screening indicator in ISDN Setup messages.

Defines the redirect reason for IP-to-Tel calls. If redirect (diversion) information is received from the IP, the redirect reason is set to the value of the parameter before the device sends it on to the Tel.

Defines the redirect reason for Tel-to-IP calls. If redirect (diversion) information is received from the Tel, the redirect reason is set to the value of the parameter before the device sends it on to the IP.

Overrides the calling party's number (CPN) screening indication in the received ISDN SETUP message for Tel-to-IP calls.

Note:

Defines (overrides) the screening indicator of the calling party's number in the ISDN Setup message for IP-to-Tel ISDN calls. This is applicable only when the device includes one calling party number in the outgoing ISDN Setup message.

Defines (overrides) the screening indicator for the first calling party number when the device includes two calling party numbers in the outgoing ISDN Setup message for IP-to-Tel ISDN calls.

Defines (overrides) the screening indicator for the second calling party number when the device includes two calling party numbers in the outgoing ISDN Setup message for IP-to-Tel ISDN calls.

Enables the device to copy the called number (from the received ISDN message for digital interfaces) 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 for digital interfaces). 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.

Note:

Enables the replacement of the calling number with the redirect number for ISDN-to-IP calls.

Determines whether the Trunk Group ID is added as a prefix to the destination phone number (i.e., called number) for Tel-to-IP calls.

Note:

Defines if the slot number / port number / Trunk ID is added as a prefix to the called (destination) number for Tel-to-IP calls.

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 8). For example, for the first trunk/channel located in the first slot, the number "11" is added as the prefix.

This option can be used to define various routing rules.

Enables the device to add the Trunk ID (from where the call originated) as the prefix to the calling number (i.e. source number).

Determines whether the internal channel number is used as the destination number if the called number is missing.

Note:

Determines whether the destination number is copied to the source number if no source number is present, for Tel-to-IP calls.

Determines whether the Numbering Plan Indicator (NPI) and Type of Numbering (TON) are added to the Calling Number for Tel-to-IP calls.

For example: After receiving a Calling Number of 555, NPI of 1, and TON of 3, the modified number becomes 13555. This number can later be used for manipulation and routing.

Determines whether NPI and TON are added to the Called Number for Tel-to-IP calls.

For example: After receiving a Called Number of 555, NPI of 1 and TON of 3, the modified number becomes 13555. This number can later be used for manipulation and routing.

Determines whether the NPI and TON values are added as the prefix to the Redirect number in INVITE messages' Diversion or History-Info headers, for ISDN Tel-to-IP calls.

Determines whether or not the device removes the prefix, as configured in the IP-to-Tel Routing table (see Configuring IP-to-Tel Routing Rules) from the destination number for IP-to-Tel calls, before sending it to the Tel.

For example: To route an incoming IP-to-Tel call with destination number "21100", the IP-to-Tel Routing table is scanned for a matching prefix. If such a prefix is found (e.g., "21"), then before the call is routed to the corresponding Trunk Group, the prefix "21" is removed from the original number, and therefore, only "100" remains.

Note:

Determines whether the device uses the number from the URI in the SIP Referred-By header as the calling number in the outgoing Q.931 Setup message, when SIP REFER messages are received.

Note:

Global parameter enabling the device to swap the calling and called numbers received from the Tel side (for Tel-to-IP calls).

You can also configure the feature per specific calls, using Tel Profiles ('Swap Tel To IP Phone Numbers' parameter). For a detailed description of the parameter and for configuring the feature in the Tel Profiles table, see Configuring Tel Profiles.

Note: If the feature is configured for a specific Tel Profile, the settings of the global parameter is ignored for calls associated with the Tel Profile.

Defines a string prefix that is added to the Redirect number received from the Tel side. This prefix is added to the Redirect Number in the SIP Diversion header.

The valid range is an 8-character string. By default, no value is defined.

Determines whether the TON/PLAN parameters are included in the Remote-Party-ID (RPID) header.

If the Remote-Party-ID header is enabled (EnableRPIHeader = 1) and AddTON2RPI = 1, it's possible to configure the calling and called number type and number plan using the Number Manipulation tables for Tel-to-IP calls.

Determines the SIP headers containing the source number after manipulation:

Enables additional destination number manipulation for IP-to-Tel calls. The additional manipulation is done on the initially manipulated destination number, and this additional rule is also configured in the manipulation table (NumberMapIP2Tel parameter). This enables you to configure only a few manipulation rules for complex number manipulation requirements (that generally require many rules).

Enables additional source number manipulation for IP-to-Tel calls. The additional manipulation is done on the initially manipulated source number, and this additional rule is also configured in the manipulation table (SourceNumberMapIP2Tel parameter). This enables you to configure only a few manipulation rules for complex number manipulation requirements (that generally require many rules).
