Anybody get a lot of invalid extension replies from the CP, even though they are putting in the right ext number for transfer?

It wouldn't be because you are pausing too long between digits, would it? That's the only time I get a message like you describe. What version of Call Pilot do you have?

I think the problem that you having could be fixed using the firmware DSP
patch from Nortel .The DSP patch is different than the call pilot s/w, so if the unit is shipped prior to may 04 it has the old DSP firmware, and even if you upgrade the system to ver 2.10.06 you still need to upgrade the DSP patch, however all the new units shipped after may 04 it has the new DSP firmware. This patch is intended for sites experiencing DTMF “echo” on CallPilot 100/150 platforms when
dialing subscriber numbers via Automated Attendant. The key being that the second digit is echoed due, typically, to a high noise to signal ratio on loop start facilities. An example of this issue is as follows:
Caller dials Company XYZ’s CallPilot Automated Attendant after being
prompted for the user’s subscriber’s number; caller dials 221, but is
routed intermittently to 222.
This patch can be loaded thru a either the Modem connection or the network connection..I hope that helps.
