Just for the record, there seems to be an issue brewing in the sip channel relative to disconnects. Example: C7960 -> * -> sip gateway -> pstn When the C7960 hangs up on a call, we see the 7960 issue a BYE to *, but * does NOT always send a BYE to the gateway. That's watching closely with a packet sniffer, all on the same wire, likely loaded SOHO asterisk.
