IP-Voice: Two Voice 2 interfaces won't connect to each other

Question:  I have two Voice 2 interfaces configured to talk to each other, the server is located at an Eclipse frame and the client is remotely located. I have a panel connected to the client voice unit, the panel doesn't connect and the four Port Status LEDs on the client voice interface blink on/off indicating no connection.  I can ping the server voice IP address so I know there is a handshake between the units. Is there anything that I should check on both units?

Answer:  If possible setup two PCs to compare the Voice 2 server and client separately on the PC browser screens.  Check the following settings to ensure a proper handshake between the two Voice 2 units:
a.  From the Configuration / Voice screen verify that both interfaces are set to the same sampling rate.  If they are different the two interfaces will not talk to each other
b.  On the Client Voice 2 unit verify that the Configuration / Voice / Server IP address is set to the server IP address
c.  Verify that the same codec is used for both the client and server voice units
d.  Verify that the Configuration / Data screen is set the same on both the client / server boxes (emulate an Eclipse panel with 19200 baud rate, 8 bits, No parity, 1 stop bit, No flow control or Matrix +3 or to NONE)
e.  Verify that the Configuration / Advanced settings screen parameters: disconnect timer is set to 7 - 10 seconds, that the TCPIP port number is set to 4569 initially and that TOS is selected for Type of Service.
