[OpenSER-Users] How to set a fixed string as acc "extra" field?

Hi, imagine I need to log two extra fields in accounting: - Source-IP - Proxy-IP "Source-IP" will be dynamic containing the value of $si. "Proxy-IP" is a fixed string value = "88.88.88.88", but... how to log this value?: * modparam("acc", "radius_extra", "Source-IP=$si; Proxy-IP=88.88.88.88") Of course the above line fails since the IP string should be a text so should be between " ": * modparam("acc", "radius_extra", "Source-IP=$si; Proxy-IP="88.88.88.88"") This fails obviously. * modparam("acc", "radius_extra", "Source-IP=$si; Proxy-IP=\"88.88.88.88\"") This fails too. * modparam("acc", "radius_extra", "Source-IP=$si; Proxy-IP='88.88.88.88' ") This fails too. Is it impossible? any suggestion? PD: Yes, I know I can do a bit "dirty" trick: modparam("acc", "radius_extra", "Source-IP=$si; Proxy-IP=$var(proxy-ip)") ... $var(proxy-ip) = "88.88.88.88"; but I'd prefer not to do it. -- Iñaki Baz Castillo
