OpenSER module avp_radius

avp_radius module allows loading of user’s attributes into AVPs from RADIUS server. User’s name and domain can be based on From URI, Request URI, or authenticated credentials.

The module assumes that Radius returns the AVPs as values of reply attribute SIP-AVP. Its value must be a string of the form:

• value = SIP_AVP_NAME SIP_AVP_VALUE
• SIP_AVP_NAME = STRING_NAME | ‘#’ID_NUMBER
• SIP_AVP_VALUE = ‘:’STRING_VALUE | ‘#’NUMBER_VALUE

“SIP-AVP” RADIUS AVP examples for OpenSER 1.2.0:

"email:[email protected]"     -> STRING NAME AVP (email) with STRING VALUE ([email protected])
"#14:[email protected]"       -> ID AVP (14) with STRING VALUE ([email protected])
"age#28"                  -> STRING NAME AVP (age) with INTEGER VALUE (28)
"#14#28"                  -> ID AVP (14) with INTEGER VALUE (28)

For AVP with STRING NAME, the module prefixes each attribute name as returned from RADIUS server by string “caller_” or “callee_” depending if caller’s or callee’s attributes are loaded.
