Overview
SIP Adaptor Profile
| Multiexcerpt | ||
|---|---|---|
| ||
The SIP Adaptor Profile object is the main construct for SIP Message Manipulation (SMM) functionality. Using SMM criteria and actions, you define SMM rules within a SIP Adaptor Profile. The SBC applies the profile to SIP messages in order to modify their headers and/or parameters. When a message comes into or out of the SBC and a SIP Adaptor Profile applies, the message is evaluated based on the set of criteria in the profile. If the message meets the criteria, it is modified according to actions defined in the profile. You can assign SMM profiles at the global, address context, zone, and SIP trunk group levels. You have the option to define profiles at any or all of these levels. Refer to SIP Message Manipulation for more information on SMM. For SIP Adaptor Profile provisioning limits, refer to SBC Provisioning Limits. |
| Info | ||
|---|---|---|
| ||
The number of rules in a profile is limited to 10,000 and the number of actions across profiles in a system is limited to 50,000. Ensure the above conditions are met before LSWU. |
Flexible Policy Adaptor Profile
| Include Page | ||||
|---|---|---|---|---|
|
The SIP Adaptor Profile can also be configured to support a flexible policy mechanism to facilitate dynamic routing and policy decisions based on any SIP message information element whereby routing and policy selection criteria are provisioned by the operator. An information element can be anything in the message, such as the following examples:
- SIP header value
- Presence or absence of a header
- String in a message body
- Parameter value
- Presence or absence of a parameter
The following CLI objects are used in supporting flexible policy and routing.
The
profileTypeparameter is used to specify whether a SIP Adaptor Profile is used for flexible policy or message manipulation (default).The
flexiblePolicyAdapterProfilezone object is used to assign a flexible policy-specific SIP Adaptor Profile to a specific zone.The
flexiblePolicyAdapterProfileSIP trunk group object is used to assign a flexible policy-specific SIP Adaptor Profile to a specific trunk group.
| Info |
|---|
For Flexible Policy and Routing feature implementation, refer to Flexible Policy and Routing Support. For Flexible Policy and Routing best practices, refer to Configuring Dynamic Policies and Routing Using Flexible Policy and Routing Feature. |

append | Append a configured value to a variable. |
asciiToBinaryAppend | Converts an ASCII string of hexadecimal digits into an array of hexadecimal binary bytes e.g. “1234” is converted to 0x12, 0x34 and appends to the SMM variable. |
| Converts an ASCII string of hexadecimal digits into an array of hexadecimal binary bytes e.g. “1234” is converted to 0x12, 0x34 and stores it to the SMM variable. |
binaryToAsciiAppend | Converts hexadecimal binary data into the equivalent ASCII string, e.g. the number 0x12, 0x34 into the string “1234” (0x31, 0x32, 0x33, 0x34) and appends it to the SMM variable. |
| Converts hexadecimal binary data into the equivalent ASCII string. e.g. the number 0x12, 0x34 into the string “1234” (0x31, 0x32, 0x33, 0x34) and stores it to the SMM variable. |

createuri message uriInfo | Create a SIP URI using following sub-parameters. The SIP URI is stored in the specified variable. The "to" type for this operation is a variable.
NOTE: Use " NOTE: SBC supports SIP URI messages containing up to 20 parameters in any SIP header. However, increasing the number of URI parameters impacts memory usage. For example, increasing the number of parameters from 10 to 20 will increase memory usage by approximately 10 percent. |

If the corresponding payload type of the specified codec is not found, “0” is stored in the variable as specified in the To operand. |
getDigits | Use this operation to use the value in the parameters to populate the SMM variable. 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. |
getPayloadType | Obtain the corresponding payload type of a given codec if the payload type exists in the media line. The value of payload type is stored in the variable as specified in the To operand.
