[SR-Users] RTPENGINE not kernalizing in some cases

[Dmitry]

hi
The cause :
the Asterisk in KVM - had no voice during internal calls, so no RTP from Asterisk - and no Kernalizing ( no RTP packets were seen from Asterisk   so the RTPENGINE daemon did not send a command to kernalize.

 Hi
I have the Kamailio and FS behind it (in Kazoo). Both are in one ip address 10.34.101.104

i use rtpengine_manage().
When I call from Asterisk which is behind NAT :1) Asterisk in VMware player  (NAT, local ip 192.168.175.136) and public 10.34.101.103 - the voice was ok? in logs I saw Kernalizing media
2)Asterisk in KVM(NAT, local 10.28.40.101 public 10.101.29.45) and no Kernalizing in /var/log/messages and no voice.

The Asterisk configs are absolutely the same.

 Kamailio log shows no errors
In both cases the INVITE's SDP connection is 10.34.101.104 - the address of the Kamailioin the ' case 1'  I see all RTP streams : 2 rtp streams - between asterisk and kamailio and vice versa, 2 -rtp streams between kamailio/rtpengine - Freeswitch and vice versa
in the second case I see the following RTP streams: 1 rtp stream - from Kamailio to Asterisk, 1 rtp stream - from Freeswitch to Kamailio
How to debug such cases?
Any help is appreciated.
