[asterisk-users] Registered successfully, but after a minute or so no SIP messages anymore

ping times are fine as well:

this high RTT appears only sometimes.  After removing STUN-server it 
looks better, did two test calls right now, both gone through 
immediately. At the end of the second test call I see:

     -- Executing [s at app-announcement-1:5] 
Playback("PJSIP/pjsip_sipgate-00000003", 
"custom/araz01&custom/07-polly,noanswer") in new stack
     -- <PJSIP/pjsip_sipgate-00000003> Playing 'custom/araz01.alaw' 
(language 'en')
     -- Contact pjsip_sipgate/sip:2636146e0 at sipgate.de:5060 is now

Unreachable.  RTT: 0.000 msec
*  == Endpoint pjsip_sipgate is now Unreachable*


Why do I have that loss of registrations?

here my pjsip config for sipgate.de:

freepbx*CLI> pjsip show registration pjsip_sipgate

  <Registration/ServerURI..............................> 
<Auth..........>  <Status.......>

  support_path             : false
  transport                : 0.0.0.0-udp

Remind: Endpoint is currently unreachable, but asterisk shows 
"Registered". Test call fails at this moment.
