Upstream VoIP is a managed
service and, in order for us to manage the service, we would prefer that you
buy the phones through us. We can then pre-configure them for you and know that
they will be 100% compatible with the service. You can rest assured that our
range of phones is competitively priced.
If you have an existing
investment in VoIP phones then it is likely that they can be reconfigured to use
with Upstream, just ask.
