FXS FXO Card Not Recognized after IOS Upgrade.

Answered Question
Mar 8th, 2010

I recently upgraded my 1760 router IOS to version c1700-ipbasek9-mz.124-25c.bin.  I now have an FXS and FXO card that are not reconized.  Any thoughts?  Did I use the wrong IOS version?  It is an older router, but I can run the IPBASE image with the limited amount of memory I have.

Attached is a show run of the router.

I have this problem too.

You need to upgrade memory, and use ip voice.

Thank you. That's what I was afraid of. I might as well just upgrade the entire router too. The 1760 is ancient!!!

I had a memory supplier with very reasonable prices. He was also able to provide the necessary rommon upgrade.
