This is particularly popular with Sheffield businesses in Digital Campus and Sheffield Business Park who want to consolidate their communications onto a single platform.

VoIP calls require approximately 100 Kbps of bandwidth per simultaneous call.

AMVIA can provision both your VoIP system and the underlying connectivity to guarantee performance.
