PSTN CONNECTIVITY: For inbound calls, local calls and 911 access, it's typically important to provide remote office with PSTN connectivity. This connectivity must therefore be planned into any VoIP implementation - rather than considered only as an afterthought.

THE QUINTUM SOLUTION: In addition to providing an "on-ramp" onto the IP network for analog devices, Quintum switches provide an "off-ramp" for packetized voice onto the PSTN. This ensures the ability of every user to access 911 emergency services. It also allows calls to be made and received via the local loop. Plus, as noted above, this PSTN connectivity provides a ready failover capability in the event of IP network problems.
