[SR-Users] Media server can't return ACK correctly

[Alexandru Covalschi]

Hi, thanks for answer

Here's configuration:

listen=udp:MY_EXT_IP_ADDR:5060
listen=tcp:MY_EXT_IP_ADDR:5060
listen=udp:MY_INT_IP_ADDR:5060
listen=TCP:MY_INT_IP_ADDR:5060
listen=MY_WS_ADDR
advertised_address = MY_EXT_IP_ADDR
alias = MY_INT_IP_ADDR
alias = MY_DOMAIN

#!ifdef WITH_TLS
listen=MY_WSS_ADDR
#!endif

port=5060

...

# ----- rr params -----
modparam("rr", "enable_full_lr", 1)
modparam("rr", "append_fromtag", 1)

>> 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.

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