hi everybody,<br><br>I bought few units for evaluation but we were not able to upgrade the firmware to 1.4 ,<br>
it's currently set at 1.2, <br>
when we go to the webadmin page, <br>
<br>
whether we try to change the IP of the tftp server or the firmware name and set values, the reply is always <br>
<br>
Invalid IP address<br>
<br>
Please try again<br>
<br>
if we change the value via the phone itself , the tftp ip is changed but the firmware does not come up ....<br>
<br>
we are sure of our tftp server since it's used to upgrade other phones from other brands ....<br>
<br>
any idea ?
