Hi, I am trying to change only the "display name" of the FROM header using uac_replace_from().However, the value is not being changed (see below) request_route { .... xlog ("L_INFO", "fu=$fu"); uac_replace_from("pbx", ""); xlog ("L_INFO", "fu=$fu"); # authentication route(AUTH); ....} Am I missing anything? Any help in this regard would be greatly appreciated. Thanks,Al
