User's Guide 1.1. Overview UAC (User Agent Client) module provides some basic UAC functionalities like FROM header manipulation (anonymization) or client authentication. Known limitations in this version: * authentication does not support qop _________________________________________________________ 1.2. Dependencies 1.2.1. SER Modules The following modules must be loaded before this module: * TM - Transaction Module _________________________________________________________ 1.2.2. External Libraries or Applications The following libraries or applications must be installed before running SER with this module loaded: * None _________________________________________________________ 1.3. Exported Parameters 1.3.1. from_store_param (string) Name of FROM header parameter that will be used to store (encoded) the original FROM URI. This parameter is optional, it's default value being "vsf". Example 1-1. Set from_store_param parameter ... modparam("uac","from_store_param","my_param") ... _________________________________________________________ 1.3.2. from_restore_mode (integer) There are 3 mode of restoring the original FROM URI: * 0 - NO RESTORE - no information about original URI is stored. * 1 - AUTO RESTORE - all sequential request will be automatically updated based on stored original URI. * 2 - MANUAL RESTORE - all sequential requests/replies must be manually updated based on original URI. This parameter is optional, it's default value being 0. Example 1-2. Set from_restore_mode parameter ... modparam("uac","from_restore_mode","1") ... _________________________________________________________ 1.3.3. credential (string) Contains a multiple definition of credentials used to perform authentication. This parameter is required if UAC authentication is used. Example 1-3. Set credential parameter ... modparam("uac","credential","username:domain:password") ... _________________________________________________________ 1.4. Exported Functions 1.4.1. uac_replace_from(display,uri) Replace in FROM header the display name and the URI part. Example 1-4. uac_replace_from usage ... uac_replace_from("batman","sip:batman@gotham.org"); uac_replace_from("","sip:robin@gotham.org"); uac_replace_from("batman",""); ... _________________________________________________________ 1.4.2. uac_replace_from(uri) Replace in FROM header the URI part without altering the display name. Example 1-5. uac_replace_from usage ... uac_replace_from("sip:batman@gotham.org"); ... _________________________________________________________ 1.4.3. uac_restore_from() This function will check if the FROM URI was modified and will use the information stored in header parameter to restore the original FROM URI value. Example 1-6. uac_restore_from usage ... uac_restore_from(); ... _________________________________________________________ 1.4.4. uac_auth() This function can be called only from failure route and will build the authentication response header and insert it into the request without sending anything. Example 1-7. uac_auth usage ... uac_auth(); ... _________________________________________________________ 1.5. Installation & Running The UAC module requires additional functionality in TM module for implementing full FROM restoring. If you use from_restore_mode 1 or 2, you will need to apply the patch replace_from.patch located in the "doc" directory of UAC module. _________________________________________________________ Chapter 2. Developer's Guide The module does not provide any sort of API to use in other SER modules. _________________________________________________________ Chapter 3. Frequently Asked Questions 3.1.
