The Viatel SIP trunk solutions are highly scalable with base call build up to thousands of concurrent calls if required without the expense or lead-time of ordering new lines. We can build a SIP trunk over any IP connection, allowing flexibility on the access technology used (Ethernet in the first mile (EFM), radio or fibre).
Viatel SIP trunk solutions have additional security features that set our VoIP offering apart from other providers in the market. Any SIP trunk setup over a Viatel access connection will only travel over the core network to our voice switching system, and not over any 3rd party internet connection. Individual customer profiles are applied to limit the call setup to / from specific customer IP addresses and can enforce a daily / monthly credit limit.
Our SIP trunk solutions are protected by a session border controller (SBC). The SBC helps protect against malicious attacks, hides the topology from external networks, protects against corrupted packet transmission and encrypts the signalling and media streams.

We can also configure the VoIP service within a dedicated voice VPN (virtual private network) as an optional security feature. This voice VPN will be protected from all external IP sources. There will be no internet routing within this VPN and the only routes allowed within the voice VRF (virtual routing and forwarding) table are the end customer sites (IP address of the PBX) and the address of the SBC.

Viatel can prioritise voice traffic (VoIP) over access connections and the core network, ensuring your voice traffic will always get sent before data streams. We will mark voice packets as EF (expedited forwarding) and with this marking will get priority across the Viatel network, ensuring the low latency necessary for quality voice calls. This will ensure no packet loss or jitter.
