1602 & 5202 phones and IPO406DS: display doesnt work

[btaran]

Hi.

We have IPO406 (will change) and 1602-5202 IP-phones. All work correctly, but display doesnt show anything, when we connect them to PBX.
When we setup (ip, mask, etc) phones - display work correctly.

Firmware PBX: 5.0 (15)
Firmware phones different.


Please, help: what can we do with this problem?

You need PoE for IP phones and I don't see 1602 or 5202 as a supported or discontinued set in the IP Office matrix, are you sure these are the correct model numbers?

Sorry, 1603 and 5602.

1603 - phone without PoE, it uses external power adapter
5602 - uses external PoE adapter.

What do you mean when you say the display doesn't work correctly when they're connected to the PBX? Were these phones already working and stopped or are you trying to get them to work on the 406?

Hm.
Turn on phone - display shows info.
Connect to PBX, check number-password - display shows it.
...And now display turned off, but phone work.

This problem with all phones. But when i connect this phones to ipo500, display work normally.

Have you tried to downgrade the firmware on the phones to match the version of the IP Office 406? It sounds like that might be the issue since the IPO 500 would probably have a newer version.
