I thing smartfones simply lack a business grade softhone implementation.

WiFi SIP phones share some problem with smartphones: battery runtime 
and, most important, roaming and handover.

In WiFi network handling roaming/handover is up to the client, this is 
the same kind of problem that arises in mobile WiFi POS systems. 
Compared to DECT standard which implements roaming/handover this is a 
major drawback.

Implementing a proper roaming/handover in WiFi networks, using wireless 
controllers and suitable access points, is very expensive. Where such 
expensive WiFi infrastructure have to be built only to properly serve 
wireless phones a DECT multicell system is definitely a winner 
considering coverage, features and battery runtime.
