40 Edge Server log analysis Demo (final INVITE and 200OK)

41 Comparison -Both INVITEs are similar in terms of candidates -Different codecs offered but there is no 415 or 488 SIP response code -Mobile client doesnt offer -Content-Disposition: session; handling=optional; ms-proxy- 2007fallback Summary - Polycom and PG looking into this for Video interop
