I am talking to an automaton which transfers a call as soon as it sends an ACK for the call. Problem is the REFER may arrive before the ACK does. What should be done with the REFER : 1. Drop silently. [Neel] Easy to do. REFER retry should take care. 2. Send error ( 5xx with retry-after ? ) [Neel] More friendly. 3. Accept the REFER and hope the ACK shows up soon ( and send BYE if it does not) [Neel] Preferred. 4. Something else ( write to your congressman about it and protest perhaps ? ) Which one would be the right action (OK 4 is not a serious choice) ? [Neel] Sounds cool. :) Thanks Ranga -- M.
