Summary:                    [regression] Asterisk drops sip messages and/or
response codes if SIP/TLS is used
Description: 
When a Snom 360 (Firmware 7.3.7) tries to register, there is a new tcp
connection. Sometimes Asterisk CLI shows Register and 401 Response, but the
phone does not get a response. Sometimes CLI shows nothing, but the phone
logs many attempts to register. Its strange and not easy to reproduce, but
here sipp is the solution.

---------------------------------------------------------------------- 
Confirmed in 1.8.3.3 and 1.8.4 (Debian packages from packages.asterisk.org)
on a variety of hardware and software phones. Disabling TLS and forcing the
phones back to TCP returns everything back to a working state.
When looking at the SIP package traces while on 1.8.3.3, I can see that
Asterisk receives TLS packages from the client and replies to them, but
these replies never make it to the client.
When looking at the traces on 1.8.4, I can see that the phone is getting
those Unauthorized messages.
So it seems that while 1.8.4 fixes the general TLS communication issue, it
now screws up the messages sent across TLS.
