like the phone is sending a BYE message, and of course Asterisk is hanging up the call and clearing the channel on the PRI.=20 I can only think of 2 possible locations for the problem: =091) The phones think they need to send a BYE before they actually do =092) The PRI/telco side of Asterisk (unlikely based on the SIP packet) Am I correct in understanding the PRI output and SIP message? If so, what can I check on the phone side of things? Or is there a 3rd (or more) place where the problem could be?
