Hello,
Just following up. Here is a link to a screen capture from Wireshark
that shows the extra byte in the Content Length header field of the
Register message.

modified.jpg
We use an SMC7004VWBR router, but tech support at SMC said the router
does not support SIP. Has anybody else seen a router make such a mod to
a SIP message ?
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
Yes we have seen that page, but it does not mention the SMC7004VWBR specifically. If it
did we could send it to SMC
tech support.
So, if I understand correctly the Content-Length has
the form:
Content-Length: 0 0
Yes. An extra zero (0x30).
