Having issues with a 5200 system running on a later version of 2.3 and SL extensions. When using certain brands of cordless phones, the phones misdial. They will dial extra digits or the wrong digits, internal or external calls. It doesn't matter wether I am using the embedded SL or an extension off the SLM-4. I have swapped out the whole chassis, the PM, and pretty much everything else. A regular phone and faxes work fine, it's just cordless phones. The only cordless phone that will work so far is a Panasonic brand. Tech support didn't really have a fix for me except to try a different phone. We tried adjusting timers/settings in the system, but nothing helped.I even upgraded to the latest emergency builds to see if that would fix anything.
So right now the customer is happy with using a Panasonic (Which we had to supply, since it was an issue with the phone system), but just wondering if anyone else has run into this issue.
