Summary:                    Registration process retries even though OK has been
returned from the provider
Description: 
I am seeing the following behaviour with several providers.

When asterisk first starts, registrations proceed well (usually).  As time
goes on, the sip channel starts "missing" the "OK" responses to outgoing
"REGISTER" messages.  In the example I've uploaded, the sixth retry
succeeds, however, I've seen even the sixth fail, resulting in over 270
retries (all with responses which should have been accepted), and messages
of the form "sip_reg_timeout:    -- Registration for 'user at provider' timed
out, trying again (Attempt https://issues.asterisk.org/view.php?id=45)

I've uploaded a SIP DEBUG for your information; the first registration is
OK; then it starts taking six "OK" responses before asterisk is happy.
