Hi, avpops module documentation still mentions onreply_avp_mode which is obsolete now: http://kamailio.org/docs/modules/3.1.x/modules/avpops.html <<AVPs are persistent per SIP transaction, being available in "route", "branch_route" and "failure_route". To make them available in "onreply_route" armed via TM module, set "onreply_avp_mode" parameter of TM module (note that in the default "onreply_route", the AVPs of the transaction are not available).>> Please remove the references. Thank you. -- Sincerely, Andrew Pogrebennyk
