NAT Issues - Elastix

  • Hey guys,

    Having some issues with 2 Cisco IP Phones registering outside the network to a Elastix box. Both phones registers fine they are:

    -Elastix server hangs the call up few seconds into a call with related error in CLI:

    I have attached screenshots of my config.
