I saw some similar info in thread690-996761. We have been having issues with all new 64xx telephones... regardless of vendor. I have purchased the telephones from three different vendors, and more often than not, we get "strange dialtone" when we go off-hook. It sounds like garbled dialtone, and it will not take any digits.
If we assign a port in the switch to the extension, then everything is fine. After that, we can TTI-separate, TTI-merge, etc. It's just the phones right out of the box. Any ideas? This has become quite a pain in the tush having to assign every port to every extension... especially when you have to track every station back through 2-3 IDF closets.
