The system it self seems to be stable enough, the real value of the EMS will be in the Mobile clients, Symbian S60 and UIQ seem to be stable enough, RIM and Windows Mobile need some more time , PC soft client working good, SIP phones are getting there, media gateway T1/E1 very stable, very nice product, so many new features, but keep in mind very new. new licenses policy. I like it, but i like every Ericsson's product.
To MD or not to MD that is the question
