MTU doesn't appear to be the problem here.

I have a feeling it is a symptom of soft-phone usage. The RTT that asterisk 
shows when doing a 'sip show peers' is based on the sending and return of a SIP 
OPTIONS packet to the user agent, in this case X-Lite. Soft phones 
unfortunately are fighting for resources on a machine and therefore don't 
always answer in the most timely fashion. If I use a hard phone, the problems 
disappear. I'm going to have to "close the book" on this one and chalk it up to 
soft-phone silliness.

Not of useful consequence, but I do find it interesting that many desktop 
phones have large varying differences in their RTT. I've got a Grandstream and 
Polycom phone on my desk connected to the same switch. The Polycom typically 
stays within 3-10ms while the Grandstream is generally 20-30ms.

Meh.
