No ideas but I also found something last night that could be related. I 
have the following:

Home SIP   <-SIP->  Home Asterisk <-IAX-> Work Asterisk

Calls from Home SIP to Home Asterisk (like vms) sound fine. Calls from 
Home SIP through Home Asterisk to Work Asterisk sound horrible on the 
SIP side. I don't know how it sounded on the Work side since I was 
checking voicemail. It occurred on every call all the time with 1.4.10 
and 1.4.10.1. Reverting Home Asterisk to 1.4.9 solved the problem.

Maybe something got "fixed" in chan_sip in 1.4.10?
