Some snapshots from the SIP Bake-Off at Columbia University,
8-9 April, 1999

Day 1 early, people frowning behind the screens


Mediatrix gear sounding better than ever


Ellemtel trying to be forgiving about SDP details


A pingtel phone with prototype flavour


Breakfast served for hard work on Day 2


Henning spelling out the procedures


Cisco plugging the voice into the router


Nortel waiting for an INVITE


An endangered species?
