Hi, just one question. I have created two profiles (suggested by @Michael) as I was having same NAT issue. Profiles are basically the same only registration port is different (5060, 5070) and NAT profile have set: <param name="NDLB-force-rport" value="true"/>. In my dialplan I have made bridge like this: <action application="bridge" data="{origination_callee_id_name='${effective_caller_id_name}',origination_calee_id_number='${effective_caller_id_name}'}user/${destination_number}.fs_test@fs_test.fs2.blabla.com" /> freeswitch@default> show re [ registrations] freeswitch@default> show registrations reg_user,realm,token,url,expires,network_ip,network_port,network_proto,hostname 018108753.fs_test,fs_test.fs2.blabla.com,40804176-fb1f176@172.31.1.190,sofia/internal/sip:018108753.fs_test@xxx.xxx.xxx.xxx:1265,1337169317,xxx.xxx.xxx.xxx,1265,udp,localhost.localdomain 018108752.fs_test,fs_test.fs2.blabla.comi,873cfe40-1224f25@172.31.1.171,sofia/nat/sip:018108752.fs_test@xxx.xxx.xxx.xxx:2097,1337170569,xxx.xxx.xxx.xxx,1920,udp,localhost.localdomain 2 total. Why only phone work which is registered on NAT profile. IF I call users which is registered on internal profile I get user not registered? Thanks! Miha
