      I have a pfsense 1.2.2 firewall setup with an ipsec tunnel connected to a Linsys RV042 router at the other end of the tunnel.
      To my knowledge the Linksys is Linux based but i do not know if it is using FreeS/WAN or OpenVPN.

      the vpn is confirmed up and functioning.  confirmed via a number of methods including ping and smb file transfer.
      the Avaya phone is confirmed working on local area network AND when both ends of VPN have rv042 routers.
      also confirmed to work with rv042 at one end and SonicWall at the other end.

      this is a tcpddump of the connection attempt via the VPN.

      It is clearly evident that i am missing something.
      Any suggestions as to what that might be would be greatly appreciated.
