We installed an update last night, and found that half our customers would
lose registration after about a minute. Packet capture shows that the
phone sends the keep-alive (an options packet), gets back a SIP 481 no
subscription, then immediately deregisters. Turning off keep-alive fixes
No contact with Digium yet, figured I'd ask if anyone else has seen it, and
also warn everyone.
