[SR-Users] CSEQ problem with SPA504G

Hello,

I could not spot a difference in method from r-uri and cseq header -- 
the error message is printed from sanity module, you can disable the 
cseq method check, see:

   * http://kamailio.org/docs/modules/devel/modules/sanity.html

But it will be important to see why is failing, can you add an xlog line 
in config like:

xlog("=== method is [$rm] and cseq [$hdr(CSeq)]\n");

and send it over here? Maybe then we can spot what's wrong there.

Cheers,
Daniel
