We use secured bandwidth such as MPLS or Leased Line circuits to connect with our customers. Most firewalls are not SIP aware and so the enterprise must choose between deploying a firewall that breaks the SIP system and implementing SIP trunking without the security of a firewall. However can bypass the office firewall by connecting the digital trunk over a secured private network.

Digital Voice Trunk



We are HD codec (G722) compatible, which delivers HD quality. This is useful for applications such as on a local area network where the bandwidth is readily available and offers a significant improvement in speech quality over older narrowband codecs such as G711. Environments where bandwidth is more constrained may prefer one of the more bit-efficient codecs, such as G722.1 (Siren7) or G722.2 (AMR-WB).
