Hi Everyone,

I have a 4 port FXO which is being used as the incoming/outgoing gateway for a CME on a 2801.

The issue I am having is that after a certain amount of time/calls the FXOs are locking up and staying offhook.

This then causes the issue of all lines being engaged. Which of course is not good.

Has anyone run into this issue before ? If not, does anyone have any suggestions on fixes for the problem ?

Thanks in advance.

Yes.. I've ran into this a bunch and it turs out to be a DSP issue. The fix seems to be to upgrade the IOS or upgrade to the latest DSP firmware. I do know that 12.4.9T1 with DSP firmware 9.2 is very stable.
