Hi list, I have this call scenario, it's just the simplest 2 sofia endpoints external profile, and a bridge application in dialplan Caller -> FS -> calee Then caller compose a REFER within current dialog, FS just handle that REFER, and contact the target sip uri indicated in Refer-To in REFER. Everything seems fine, since FS follow rfc3515 as a user agent, legs bridged Target transfer -> FS -> callee But I actually want my callee to receive and handle REFER message, any trick to do that? I'm thinking of creating new REFER within dialog to callee when FS receive a REFER from caller, but not sure if it's possible or how. My FS version is 1.6.12 rgds, Loi Dang Thanh Phone : 841224.735.448 Email : loi.dangthanh@gmail.com
