I have a customer who moved to their new office today. The service provider installed a new Cisco IAD2400 to provide 5 analog lines to be connected to the CIX 40. We moved the CIX from the old location.

Now when we go offhook on any line, the Cisco IAD intermittently thinks it heard a 1 dialed and breaks dialtone, waiting for more digits (even though I've dialed nothing). Previously had this problem and I told the provider to set their inputgain to 0db. But in this case it doesn't seem to affect it much or may even make it worse.

Anyone see this before or have any luck getting it sorted out?
