Maybe the sipura transfer is using a sip reinvite or some other SIP command. Does the consultative transfer works when the other parties are not attached to a sipura phone (ie when a sipura phone try to make a consultative transfer from a grandstream to a snom) ? >From what you said, I believe that asterisk is not managing these consulative transfers and is not aware of. These are inter-phone communications (peer to peer). Each peer has to understand each other, which is not easy when mixing multiple technologies. Does it sounds right for you ? _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
