HOW DOES IT WORK?

POST ensures that all SIP traffic is transferred from your SBC to the VoIP platform via its secure end-to-end network.

As the transfer of voice traffic is controlled entirely by POST, the Corporate SIP Trunk offer guarantees:

  • A secure service: POST's SIP Trunk routes communications through its extremely secure private network that is separate from the Internet. It is, in particular, this dedicated line that guarantees the Quality of Service, prioritising voice transmission that is completely separate from the public Internet.
  • Quality of Service (QoS): Quality of Service is a network's ability to transfer a type of traffic by ensuring the availability, speed and transfer time, which has a direct impact on the quality of outgoing and incoming calls.
  • Complete control of the line: the service is managed from start to finish on the POST network from your PBX to our VoIP platforms.
  • Line redundancy: thanks to the Carrier Ethernet solution, Corporate SIP Trunk lines are redundant: all the channels are distributed between two links (or more) and each of these links is responsible for half of the channels you have subscribed to. If one of the two links is lost, the redundant link still active will support all the channels. The redundancy with Corporate SIP Trunk is optimised by maintaining the total number of SIP channels subscribed to even if one of the links is lost. Redundancies are validated by a POST Expert check for enhanced security!
  • Great flexibility in the number of channels: distributed between project SIP Trunks: you can upgrade or downgrade the number of channels to meet your needs for all your sites.
  • SLA Premium+ for the highest SLA on the market including for redundancy projects. A solution which supports an unlimited number of channels on a single trunk as it is built on symmetrical Carrier Ethernet lines.
  • Assistance from our experts for a design that meets the requirements of complex infrastructures.
