IAD2400 FXS issues

Unanswered Question
Jun 28th, 2010

Hello,

I am fairly new to the IAD line of cisco devices so forgive me if my question is something obvious.  I recently purchased an old IAD2421-8FXS for use in my home lab and pretty much have it hadnling my analog handsets and connecting to my 1760v which hosts my IP phones running SCCP.  Calls from the IP phones across the local network to the IAD work great and so does the voice quality, however calls from the analog phones (connected to the FXS on the IAD) to the IP phones or to the PSTN (FXO card in the 1760v) are muffled and the voice breaks up.  I am wondering if this may be an attenuation issue or an input gain issues on the FXS ports, or do I just have a bad IAD unit.  Below is my IAD config.  Any help is appreciated.

Thanks

-Jeff
