[SR-Users] e72 stops responding

[hiro]

8 is a Nokia E72 calling in via kamailio. After the Invite I don't get
any other packets from the phone any more. It seems like the TCP
connection gets killed completely by something. It only starts working
again after I reboot the phone and it is completely reproducable.
