Increase in Bit Errors on incoming phone call

Hi
I've recently installed a new router and have noticed jumps in the Bit Errors.  On trying to eliminate how these are occurring i seem to have narrowed it down to incoming calls.  The last two calls the errors have increased by approx. 1500.  I can't say i noticed this on the router that i replaced.  I've recently had a new master socket replaced by BT after a line fault, this has increased my sync speeds to the router stats below.
The router is plugged into the master socket with a filter, one extension to cordless phone downstairs with a filter on this, no ring wire on extension.
Any thoughts on what is causing this and how to stop the errors, or do i need to be concerned as everything seems to be working OK?

Re: Increase in Bit Errors on incoming phone call

Could somebody with more technical knowledge give me some advice on this. The router is now in the test socket with a new adsl nation XF-1e filter. their is no phone connected and the Bit Errors still take a big jump on an incoming call, just tested with a call from my mobile.
Some stats below.

would this indicate a line fault ?
Any advice would be much appreciated.
