[Freeswitch-users] Blog post about SIP

[Kristian Kielhofner]

FreeSWITCHers,

  As some of you may have noticed I frequently comment on SIP-related
FreeSWITCH posts.  Long story short I decided to finally put some of
these thoughts and experiences down in writing.  What I ended up with
is a 21 page (and counting) document describing various SIP header
fields, SDP information, RTP issues, DTMF issues, NAT traversal
technologies, interop headaches, etc.

  I wrote a little intro and linked to the document if any of you
would like to check it out (link at the end of post):

  Of course I'd appreciate any feedback you may have.  What do you
disagree with?  Find a typo?  Have burning SIP/RTP/SDP/T.38/codec
questions you'd like to see me address?  Should I get into more
implementation (FreeSWITCH) specific issues?  Let me know.

Thanks!
