in the set-up
UAC(A)----------------SER-------------UAC(B)
if A calls B and then A hangs up all is fine, if A calls B and then B hangs up a 481 Call leg/transaction error occurs, this does not even get sent to the A client, the 481 is generated by SER. B then thinks it is still in a call.
Should BYE messages be relayed? because it seems the server does not relay any BYE messages at all (even the ones that work) according to tcpdump.
Using SER 0.8.14 in record_route (this is a requirement) and MS RTC based clients.
Thanks
