IP-PBX Telephony Services

Virtual Access CPE technology is also very well suited for IP-PBX services. In these situations the VA router acts as the IP gateway to the WAN for remote handset access, distributed satellite working or IP trunking services. Where SIP-based IP-PBX configurations are used the key features offered are much the same as with IP-Centrex VoIP environments.

Many IP-PBX configurations use propietary signalling however, and incorporate the rich features of the manufacturers proprietary handsets.

In situations where Internet access broadband services are used with proprietary signalling, the VA router offers some further key benefits. In these situations, centralised configuration of GRE or IPSec VPN tunnelling simplifies the process of IP handset address management.

At the customer site, the network appliance can monitor the local IP-PBX interface and provide connectivity information on both broadband and LAN for either periodic reports or network alerts.

In summary, the Service Managed Gateway (SMG) offers:

  • Clearway™ traffic management to manage and prioritise VoIP and data over the non-QoS network;
  • Appropriately marks VoIP packets for QoS compatibility with network-based QoS services in conjunction with MPLS networks
  • Locally implements Call Admission Control (CAC) to block excessive outgoing VoIP calls and therefore maintain the required voice quality
  • Provides VoIP call quality measurement reports and statistics for SIP-based services

Our polling services can produce critical statistics instantaneously or as periodic reports on issues such as latency, jitter, and availability.

Finally, the Zero Touch process requires no expertise to install the Customer Premises Equipment (CPE). The network appliance and additional equipment such as cables and VoIP telephones can all be shipped as a single package with a set of site-specific instructions. The customer just plugs in the cables and Activator configures the service.
