I don't know that router but have dealed with other SMC routers and they *do* 
include SIP-ALG built-in, and the worst: it cannot be dissabled in any way!

Check at this page (the list of SIP-ALG routers):
  http://www.voip-info.org/wiki/view/Routers+SIP+ALG

So, if I understand correctly the Content-Length has the form:
  Content-Length: 0 0
???
