I can tell you what I know about CW, and that is that I have never heard of a stutter dial tone being generated after the flash. There would be no reason for a dial tone, because what your customer expects (and what every description of CW states) is that the second caller will immediately be connected, as the first caller is put on hold.

There is something screwy with the CO programming.

If you call the Verizon business office for large accounts, you might be able to get them to fax or email the instructions.
