Check from the sites in question using "testmyvoip.com" or whatever the
site is called.
In the UK I found that some strange things sometimes happen. At one
point I was sure that BT were perhaps misclassifying IAX packets as
P2P... However, not had a problem with SIP.
Beware that ADSL uses vastly more bandwidth than you expect on small
packets, eg if you are classifying using a cheap router then you
probably need to at least half your claimed bandwidth in order to make
the prioritisation work correctly. I added some (hack) patches to fix
the linux calculation for HTB on the linux QOS list a year or two back.
If you have a linux router you could use those to improve the
calculation quality for QOS - or else I found a Draytek router does
impressively well at getting it right for small sites...
Very likely you will find that the issue is variable jitter on the
line. The link above should help you figure this out
Good luck
