Benefits
SVI-MG Media Gateway Controller Function
Excellent ROI – Provides clients with a flexible approach to their network deployment allowing then to choose from:
► Single Vendor
► Squire Technologies can supply the entire solution with the SVI_MGF. The SVI_SG Signalling Gateway and SVI_MG Media Gateway reduce complexity in operation and support, thus reducing OPEX
► Multi Vendor
► Alternatively the SVI_MGCF supports third party Media and Signalling Gateways allowing clients to choose their gateways to match their specific requirements or re-use existing infrastructure to minimize CAPEX.

Benefits
SVI-MG Media Gateway Controller Function
► Investment in equipment is based on
real demand. Scale the SVI_MGCF to
match clients’ bandwidth requirements as
and when needed through software-
based license key updates
► Flexible software delivery and
deployment model allows rapid remote
deployment and avoids shipping and
import issues
