1 Manipulating SIP Status-Line Header of SIP Responses The SIP status line is a SIP response header, and it can be modified like any other SIP headers of a message. it can either be modified with a user-defined value, or the status line from an incoming response can be copied to an outgoing SIP response. The SIP header keyword used for the response status line is SIP-StatusLine. Feature Information for Manipulating SIP Responses, on page 1 Copying Incoming SIP Response Status Line to Outgoing SIP Response, on page 2 Modifying Status-Line Header of Outgoing SIP Response with User Defined Values, on page 5 Feature Information for Manipulating SIP Responses The following table provides release information about the feature or features described in this module. This table lists only the software release that introduced support for a given feature in a given software release train. Unless noted otherwise, subsequent releases of that software release train also support that feature. Use Cisco Feature Navigator to find information about platform support and Cisco software image support. To access Cisco Feature Navigator, go to An account on Cisco.com is not required. Table 1: Feature Information for Manipulating SIP Responses Feature Name Releases SIP Profile 15.4(1)T Enhancements for SIP Cisco IOS XE responses and error Release 3.12S codes Feature Information This feature extends SIP profiles to allow the following: Modification of the outgoing SIP response status line. Previously, only modification of outgoing SIP requests and responses was possible. Copying of the incoming SIP response status-line. The information from the peer-leg status-line can then be copied to user-variables and applied to the outbound response status-line. This option can be used to pass-thru the error-code and error phrase from peer-leg. Previously, only copying of SIP headers were possible. Before applying a SIP profile to a response from CUBE, the response can be mapped to its corresponding request. 1
2 Copying Incoming SIP Response Status Line to Outgoing SIP Response Feature Name Releases Feature Information Support for conditional header manipulation of SIP headers 15.1(3)T Cisco IOS XE Release 3.6S This feature allows users to copy content from one header to the another. This is done by copying the content of messages into variables which can then be used to modify other SIP headers. This feature modifies the following commands: voice class sip-profiles, response, request, voice-class sip copy-list, sip-header Copying Incoming SIP Response Status Line to Outgoing SIP Response To copy content from the status line of an incoming SIP response that a device receives to an outgoing response, configure a SIP copylist for SIP status line and apply it to an incoming dial peer. A SIP profile must be configured to copy the status line of an incoming SIP response to a user-defined variable and apply it to an outgoing SIP response.
