ping times are fine as well:

[root@freepbx asterisk]# ping sipgate.de

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@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:263614...@sipgate.de:5060 is now Reachable. RTT: 493.094 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.......>
==========================================================================================

 pjsip_sipgate/sip:sipgate.de:5060 pjsip_sipgate     Registered

 transport                : 0.0.0.0-udp

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