Hello Jimmy, Have you tried "sip_sticky_contact=true"? (there's no documentation but here's the wiki page: http://wiki.freeswitch.org/wiki/NAT_Traversal#sip_sticky_contact) I had kind of same issue as you and this solved my problem! Florent Le 18/04/2014 13:50, Jimmy Chang a écrit :
Hi,
I've tried NDLB-connectile-dysfunction, but to no avail. SIP_Client1 and SIP_Client2 are all in the same 3G network, so I couldn't figure out why FS treated them in different ways.
Thanks. Jimmy

BYE is sent to the address in the Contact header of the INVITE.
When a client is behind NAT that can mean the client gives an incorrect address (its internal not external IP which isn't reachable). In this case I assume there's some carrier NAT happening.
If the client has STUN support that can work around it, or you can use one of the NDLB options - try NDLB-connectile-dysfunction

Hi,
We have two different SIP Clients and they all use 3G to connect to FS. SIP_Client1 receives BYE without problem but SIP_Client2 couldn't. In the SIP_Client2 case, I don't understand why FS sended BYE to 100.77.163.183 rather than 42.71.215.54. Here are the snippet of FS log.
