Originally sold customer an Abrivo 924 (same as X-Blue 45P.)

Upgraded system chips to use new X-Blue cordless phones and was told to use only U2 and U3 chips so I did and got stutter dial tones on all lines when I pressed a line button. SO....

I eventually upgraded to 9 lines and got latest new software and this time put in all THREE chips and...Stutter dial tone on all lines when you press a line button.

Has anyone else upgraded an Abrivo 924 to X-Blue 45P and seen this? The cabinets are identical and I have obviously defaulted the software twice.

Thanks for any references you may have. The customer is pretty much OK with the crazy dialtone that way but it seems weird and they don't have VM on all the lines, it is a 4 line rotary, two private lines and a third door type line.
