Yep that was a sip-b call flow.

sip-b (sip for business) was a series of call flows sylantro had 
authored into an open standard to bridge the feature gap between sip and 
key system / mgcp systems. It sort-of worked but never got industry 
adoption. Pretty much useless now unless you happen to be doing hosted 
PBX on a Synergy platform which i doubt many people are (we still have a 
small number of legacy customers on our synergy platform).
