I had this same problem and I don't think it is related to mod_callcenter.
I had also sent a post in regards to this here:

I figured that this generally happened when my caller leg was connected on
G711ulaw and agent leg was connected on G722 codec. When both the caller
leg and agent leg was same the recordings were clear. Can someone please
confirm if this could be the problem !!
