VoxCorp and Pervasip are one and the same. VoxCorp is a fully owned subsidiary of PVSP.
Both, as PVSP.pk, are losing oddles of money every single quarter. VoX and VoX Mobile are trade names for VoxCorp/Pervasip. I fail to see your point.
Pervasip has a negative book value of ($53,999,011). Under Paul Riss they have lost to their shareholders $54 million dollars, and they're not done yet.
Every shareholer and investor who lost those millions of dollars thought the CEO would deliver. They have been all wrong so far.
