Just try connecting the two systems and see what happens!
I recommend putting them on the same LAN so there is no routing/NAT issues. Then use a hub or switch that allows IP packets to be mirrored to a PC running Wireshark. By trying different combinations of settings and watching for the results, I have been able to use almost any SIP phone or SIP Trunk. However, I have not tried to QSIG or Tie Line a system - yet.
Good Luck,
