In this section:
The

acts as SIP-I Back-to-Back User Agent (B2B UA) for packet-to-packet calls supporting SIP-I Embedded ISUP interworking which is explained in the following section.SIP to SIP-I Interworking
The
Unable to show "metadata-from": No such page "_space_variables"
supports the ability to take the tef-callref parameter received in the R-URI header of an INVITE message and convert it into the ISUP network call reference parameter with the parameter code 0xf4. The parameter is stored in the CDR and mapped into the SIP-I signaling on the egress side. The length of the added field is fixed at seven bytes (including type/length).Example message:
INVITE sip:+457912345678;tgrp=garps;trunk-context=rfi.com;tef-callref=7AF0731E04@srsbc1sip.maqueta;user=phone SIP/2.0
SIP-I Embedded ISUP Interworking
The
Unable to show "metadata-from": No such page "_space_variables"
supports interworking between standard versions and country variants of the ISUP MIME body embedded within SIP-I. The following main SIP-I variants are supported:- ITU
- ANSI
- TTC
- ETSI
- UK ISUP. Scenario:
- ISUP (Country variant) — GSX9000 — GW-GW — Unable to show "metadata-from": No such page "_space_variables"— SIP(I) — Peer switch
The
Unable to show "metadata-from": No such page "_space_variables"
SIP-I implementation supports the ISUP base values defined in RFC 3204. All the other ISUP variants supported by Sonus can be supported as Specific Content Type versions.ISUP Super Generic Digits
The
Unable to show "metadata-from": No such page "_space_variables"
supports processing Super Generic Digits (SGD) received in 'sgd' parameter of P-Sig-Info header of SIP INVITE message, and mapping them to Generic Digits parameter of Number Type 25 in SIP mime, and vice-versa. This applies to both SIP-SIP and GW-GW call flows.The maximum length of SGD digits supported in P-Sig-Info header is 160 characters (0-9, a-f, A-F) which maps to 80 octets in SIP-I mime with a Binary encoding scheme, and vice-versa.
The PSX IPSP flag “Map SGD in P-Sig-Info Header” controls sending the “sgd” parameter in P-Sig-Info header in the outgoing SIP message. The CLI syntax to configure ISUP Signaling Profile to allow Super Generic Digits in the egress mime is shown below:
The interworking of SGD parameter and SIP P-Sig-Info header is not applicable when the

is configured for ERE mode.% set profiles signaling isupSignalingProfile <profile name> allowSGDinGenericDigits <supported | unSupported>
Bit H of Backward Call Indicator
The
Unable to show "metadata-from": No such page "_space_variables"
is configurable to allow the insertion of the BIT H parameter in the outgoing Address Complete Message (ACM) MIME of the 18x response using the ingress IP attributes flag, set-cut-through-indication-in-OBCI, for IP Signaling Profile attached to the ingress trunk group.The ACM message sends Backward Call Indicators (BCI) to signal information about the call setup. Most of the fields contained in the Backward Call Indicators are the same as those in the Forward Call Indicators (FCI), which are contained in the IAM. While the FCI signals the call indicators in the forward direction to provide information on the call setup to the terminating access (and intermediate nodes), the BCI signals similar information in the backward direction to the originator.
Bit H of the Backward Call Indicator (in ANSI) allows a network node to temporarily halt call set-up and play tones or announcements, or both, and collect additional in-band information from the calling user before routing the call further.

ISUP Mime Enhancements
The
Unable to show "metadata-from": No such page "_space_variables"
SIP Message Manipulation (SMM) allows for direct manipulation of the ISUP parameters within the ISUP MIME message body of a SIP message. Currently, this enhancement applies to Japan and ITU ISUP variants.These rules are only intended to be used by someone who is familiar with the ISUP message/parameter formats. If in doubt on how to write the syntax for a specific operation, please contact Sonus TAC for more assistance.
Three different ISUP parameter formatting types exist as depicted in the table below.
ISUP Parameter Formatting Types
| ISUP Formatting Type | Description | Example |
|---|---|---|
| Mandatory fixed | This type has a fixed size. It must be present in the message, and can only appear once in the message. | Nature of connection parameter in IAM |
| Mandatory variable | This type has a variable size. It must be present in the message, and can only appear once in the message. | Called party number in IAM |
| Optional | This type can be of a fixed or variable size, and can appear one or more times in the message. |
Three different ISUP parameters types exist within the SMM rules as described in the table below:
ISUP Parameter Types Within SMM Rules
| ISUP Parameter Type Within SMM Rules | Description | Examples |
|---|---|---|
| Single instance | Parameters that can only appear once in an ISUP message. These are identified by a parameter code. | called party number |
| Repeatable parameters | Parameters that can appear in an ISUP message multiple times. Each of these parameters contains a parameter field (subtype) to identify a specific instance of the parameter. These are identified by a parameter code and parameter sub type. | generic digits = type of digits generic number = number qualifier generic notification = notification indicator |
| Embedded parameters | The access transport parameter can contain a list of other parameters. These are identified by a parameter code and embedded ISUP parameter code. | called / calling sub-address information |
SMM Operations/Actions
The SMM provides the capabilities to perform the following operations:
SMM Operations/Actions
| Operation | Description |
|---|---|
| Exists | This operation allows for the operator to check whether a parameter is present based on message code, parameter code, subtype or embedded parameter code. It is also possible to provide a pattern of bytes to match on the parameter, the length of the pattern needs to be less than or equal to the length of the parameter in the message. The parameter code is mandatory in this operation. |
| Add | This operation allows for a parameter to be added into the message, in this case the parameter or embedded parameter needs to be created in an SMM variable. In the case of embedded parameters if the access transport parameter does not already exist within the message then it is automatically created in order to populate the embedded parameter. |
| Add digits | This operation only applies to parameters calling party number, called party number, called IN number, location number, redirection number, original called number, redirecting number, connected number of generic number. This operation can be used to either add or replace the digits within these parameters. The operator needs to create a variable containing the ASCII string of characters; this can either be hardcoded or populated based on the contents of a SIP header, e.g. R-URI. As part of this operation, the ASCII string of digits are converted into Binary Coded Decimal (BCD) format so the odd/even indicator field within the ISUP parameter is set correctly. If the parameter already contains digits, they are replaced with the new information. These parameters can be created in two step:
If the addDigits operation is attempted and the associated parameter does not already exist in the message then it will fail. If the ASCII string contains a + then this will be dropped as part of the conversion as there is no mapping into the ISUP parameter. |
| Delete | This operation allows for a parameter to be deleted based on the message code, parameter code, subtype or embedded parameter code. It is also possible to provide a pattern of bytes to match on the parameter, the length of the pattern needs to be less than or equal to the length of the parameter in the message. The parameter code is mandatory in this operation. In the case of embedded parameters within the access transport, when the last embedded sub parameter within the access transport is deleted then the access transport parameter is also deleted from the message. Only optional parameters can be deleted. |
| Get Digits | This operation only applies to parameters calling party number, called party number, called IN number, location number, redirection number, original called number, redirecting number, and connected number of generic number. The operation is used to convert ISUP BCD format to regular number format (i.e., can be used to retrieve the digits in ASCII string format for the specified parameter to a variable). |
| Modify | This operation allows the contents of an existing parameter to be swapped with new information. The operator needs to read the whole parameter into an SMM variable they can then edit the contents of the variable using bitwise operators e.g. AND, OR to update the contents of the specific bits in the specific bytes of the ISUP parameter. The updated parameter contents can then be swapped into the ISUP message again. |
Clicking on an operation in the above table which includes a hyperlink takes you to an example later in this section.
| Legend |
|---|
bitOR – Bitwise OR operation bitAND – Bitwise AND operation bitXOR – Bitwise eXclusive OR operation bitNOT – Bitwise NOT operation that is, inverts the bit from its current value. binaryToAsciiStore – This operation converts hexadecimal binary data into the equivalent ASCII string for example, the number "0x12, 0x34" into the string “1234”. binaryToAsciiAppend – This operation converts hexadecimal binary data into the equivalent ASCII string for example, the number "0x12, 0x34" into the string “1234” and appends it to the end of an existing ASCII variable. asciiToBinaryStore – This operation converts an ASCII string of hexadecimal digits into an array of hexadecimal binary bytes for example, “1234” is converted to "0x12, 0x34". asciiToBinaryAppend – This operation converts an ASCII string of hexadecimal digits into an array of hexadecimal binary bytes and appends them to an existing binary variable. |
