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.

I also have the same issue, using csipsimple ( based on pjsip ) android
client.

Trying to debug the issue i discovered some strange things: it seem that *
answer
to register request with data from "older" requests.

Let me say, for example, i send a REGISTER request with CSeq 1, * answer
with a 401 and CSeq N.

After few minutes, i send another register request with CSeq 2. * answer
with a 401 and CSeq X.

after few minutes, i send another register request with CSeq 3, * answer
with a 401 and CSeq 1, and also the others header copied from my first
register request. 

In pratice it seems that it is something like "desynced".
