anyone test there UA virtual IP phone Desktop on VPN.
It works fine in same network or the 2 different network connected each other.I find problem to connect over VPN. Logically if you are able do telnet session then IP Phone should get connected and I should be able to receive calls.

Hello

You depend on the ports that you have opened on your VPN, a series of ports exists that you must be able to open, for the example the one belonging to tftp UDP/69 if some of the ports that IP utilizes the virtual UA phone Desktop is not sincere it is not going to work correctly

A document in the BP exists ( Synthesis of IP flows in OmniPCX Enterprise solution) That you describe the ports that each application utilizes

Hello..

I used 4068 over VPN and works perfect.

Check also the bandwith required by a voice flow in relation to the codec used.

I have this trouble too with My Phone Ip desktop.

I think will trouble with MTU size in eth0 in Call Server MTU:1500.

(E)oxe-ze> ifconfig
eth0 Link encap:Ethernet HWaddr 00:80:9F:36:82:58
inet addr:192.168.0.2 Bcast:192.168.0.255 Mask:255.255.255.0
UP BROADCAST RUNNING MTU:1500 Metric:1
RX packets:194 errors:0 dropped:0 overruns:0 frame:0
TX packets:102 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:100
Interrupt:12 Base address:0x5000
I want chnge it to 1300.

This problem is only CS.
In GD or GA is MTU OK - MTU:1496

My Phone Ip desktop first connections to TFTP on CS, after downloading file from CS application is ready, but on downloading from TFTP error.

How change MTU in CS??

I know this config file
/etc/sysconfig/network-scripts/ifcfg-eth0
I add string MTU="1300" to the config file

DEVICE="eth0"
ONBOOT="yes"
BOOTPROTO="none"
IPADDR="192.168.0.2"
MTU="1300"
NETMASK="255.255.255.0"
NETWORK="192.168.0.0"
BROADCAST="192.168.0.255"

But not work after reset PBX.
MTU is same as before

I change MTU via string in console.....

Why you think the trouble could be the MTU?. Try using Ethereal and check when the error happend.
