Sure!

Here it is:

--pascal-boundary
Content-Type: application/sdp

--pascal-boundary
Content-Type: application/resource-lists+xml

<?xml version="1.0" encoding="UTF-8"?>

 </list>
</resource-lists>

--pascal-boundary--


I was checking the nathelper source code (nhelpr_func.c) and it looks that only a content-type of application/sdp is accepted.

-pascal

Hi Pascal,

could you please attach the INVITE body?
