Service Overview
Voice Quality
Early VoIP adopters reported poor call quality and drop outs, often caused by Internet congestion and poor network management. We’ve adapted our system to maintain control over the flow of voice traffic from a user’s handset to the PSTN, using Quality of Service technology and our own data networks.
Where a site requires a connection over the Internet for voice, we can pre-qualify and guide you to ensure a minimum ISDN level of voice quality can be achieved. This means that your calls will get through every time.
Legacy PBX Support
We can provide a gateway to interface with your existing legacy PBX so you get full call saving rates, with minimum additional investment and shorter installation time.
Lync Support
Our hosted Lync solution supports direct SIP trunking with Microsoft Lync servers, allowing for greenfield deployments. You can also route outbound calls from Lync to Over the Wire, saving money while maintaining ISDN for inbound and fall-back services.
