Hi Alexandru

How is your configuration about Public IP and Private IP?

Do you use advertise?

Maybe you need to force Outbound traffic to Public IP Socket and inside traffic to Private IP .

Do you have double record routing?

Hello everyone.

The setup is:

Carrier ip is CARRIER_IP

Public network Kamailio IP will be PUBLIC_IP

Private network Kamailio IP will be KAMAILIO_PRIVATE_IP

Private network Freeswitch IP is FREESWITCH_PRIVATE_IP

ACK

CARRIER_IP -> PUBLIC_IP->FREESWITCH_PRIVATE_IP

And freeswitch tries to actually send ACK back to PUBLIC_IP which he can't access.

Kamailio trace: http://pastebin.com/raw/1W1sXuUa

Freeswitch trace: http://pastebin.com/raw/KkZCwTTJ

request_route: http://pastebin.com/raw/Y17pXUGY

NATMANAGE route: http://pastebin.com/raw/0BpPDjN0
WITHINDLG route: http://pastebin.com/raw/5LpwSigF

I'm seeking help with that - what parameter I need to change/add to solve that?

Maybe it's a networking problem - but why then ACK reaches Freeswitch and all other requests flow OK?

Thanks in advance, Alex
