No, not with asterisk itself. > Which telephony feature would loose without REFER method ? AFAIK none except the ability to REFER (obviously). What you can do is: -route calls via a proxy that gives you the ability to modify SIP on the fly (e.g. kamailio) -wihh chan_sip use disallowed_methods (= REFER) -with pjsip reject a REFER in the dialplan: https://wiki.asterisk.org/wiki/display/AST/res_pjsip+Remote+Attended+Transfers The last 2 options will make PBXs/endpoints that use REFERs, since asterisk is advertising it, fail in certain scenarios. So cleanest is the first option, which will take some work redesigning your setup but might be a good thing on the long run. -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- Check out the new Asterisk community forum at: https://community.asterisk.org/ New to Asterisk?
