      My problem could be related to NAT and OpenVPN.

      My pfSense Config (pfSense 2..1.4):
      OpenVPN server configured with tunnel - 10.0.1.0/24
      OpenVPN client tunnel - 10.0.1.201
      LAN Subnet is - 192.168.1.0/24
      Client Machine - 192.168.1.201
      SIP-Phone on Client Machine - 192.168.1.201
      Elastix PBX - 192.168.1.240 | not an OpenVPN client yet
      SIP-Phone - Zoiper
      Client Machine OS - Linuxmint 17 64bit

      Network Setup

      Client Machine and Softphone (OpenVPN client with 10.0.1.201 tunnel IP) = machine –- pfsense --- gateway
      Elastix PBX = machine --- pfsense -- gateway

      The Problem:

      Trying to make an outbound call, first I tried dialing *60 to call the PBX clock, it works fine when client machine is not connected to the VPN. But when connected to the VPN, call is drop after 6-7 seconds.

        Might need to use static ports on your asterisk box. Chane to manual nat then create a rule for your pbx to use static ports. Also on your remote end make sure your router is not using ALG. (Application Level Gateway)
