Benefits


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


► 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
