Funny thing about codecs.. Sometimes you will get better quality audio and 
less chop when using ulaw on crappy connections. Why? Very simply because 
it sends less total audio information per packet, so it can withstand 
dropped packets a lot better than a highly compressed codec, especially 
with a good jitter buffer and PLC implementation on the other side. I'd 
expect that Vonage is running something with a decent PLC and Jitter 
buffer, which would explain your results.

Try using CVS head and enabling the SIP jitter buffer and PLC code w/ Ulaw 
and see if it improves your results.
