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?

 

Voice enabling Columbia University
