What IOS version are you running? There are a couple bugs that match what you're seeing.

May not be visible, but it addresses this issue, and it's resolved in the latest 12.2 mainline releases.

Thanks your reply! The IOS should be 12.1(5)T8 of 1750 with 2 FXS voice interface card. I can't serach the bug CSCds76940 at the bug tools. When I serach it, it display error as following:

Sorry -- The defect you have requested CSCds76940 cannot be displayed.

This may be due to one or more of the following:

The defect number does not exist.

The defect does not have a customer-visible description available yet.

The defect has been marked Cisco Confidential.

Thanks your help!!

If you're running 12.1T code, then I would suggest upgrading to 12.2(10b) which is available off of CCO, it has the fix for the bug I provided.
