We had our OS7200 MCP upgraded to a MP20 and the system software upgraded to V4.75 last week. Immediately after the upgrade we starting having problems with some of our ITP-5121D sets in the field. The person calling the ITP-5121D can hear the person on that set loud and clear but the person on the ITP-5121D can't hear the caller clearly - everything is garbled. This happens both for remote and local sets. After further investigation it appears that all the ITP-5121D sets that exhibit this problem are on V3.11. Meanwhile, all the sets we have that are still on V3.00 work just fine. Thinking that a newer software version would fix this, I installed V3.37 one one of the sets that was at 3.11 but unfortunately the problem remained.
I am wondering if anyone has experienced this problem and has a solution? I don't believe there is a newer ITP software version as Samsung stopped supporting these sets a wile ago. Alternatively, if anyone has a copy of the very old V3.00 ITP software I could try downgrading the sets running V3.11. While not a great solution I am desperate for any solution as I have several remote staff with unusable sets right now and need to get them up and running ASAP. Thanks for any help you can provide.

Was able to determine that the two remote sets we have that work are actually ITP-5021D sets so it appears maybe it's not the software but something with the ITP-5121D sets. Any suggestions on what we can try to get the ITP-5121D sets working? Thanks again.

Did you use the old db from the MCP card?
If so this can make strange things happen, if you use an old db don’t upload anything within 5.2 and do Theas settings manually after update.
Why are you using 4.75 and not 4.80?
We have phones with 3.37 on 4.80 working with no problem.

Are you using an old MGI card or mgi16 /OAS?
We have had problems with old MGI module cards and always replace them if we change from MCP to MP20
If you use mgi16/OAS, what FW version is used?

I have a site running primarily these handsets off a MP20 with 2 x MGI16 cards with no issues.
