Kindly point me in the right direction.I have the following setup.
Softphone --> Dsiprouter --> Freepbx
Each one of these is seating on a different public ip address.I have chan_sip extension on Freepbx.When i register my softphone, it returns error 408.
Sngrep tool shows that packets from the softphone indeed reaches the dsiprouter server.tcpdump on the Freepbx interface also indicates that packets from the dsiprouter hits the server.Both ports 5060/5160 are open Freepbx server but somehow the extension is not registering.
At this point i’m clueless.Pointers are appreciated.
