Management Customer [Customer Name] DID

A Direct Inward Dial (DID) number is one that exists on the public telephone network. When dialed, the carrier delivers the call to ConnexCS, which then passes it to the customer based on the settings configured here, allowing inbound calls to bypass a PBX or other routing to connect directly to the destination number.

Create and edit DID (Direct Inward Dial) parameters within the individual customer cards, either using Bulk Upload or manually Configure DID as shown below.

  • RTP Proxy Mode: If connection via our service fails, and relaxed is selected, it will failover to backup automatically.

    Strict- This will enforce the proxy engagement.

    Relaxed- This will perform best efforts to engage the RTP Proxy, if it can't then the calls will connect directly.

  • RTP Media Proxy: This defaults to Auto but selecting a zone (by continent) is the current recommendation. The following options allow you to set where RTP media server for this route for this customer:

    Auto- Selects the least expensive path between your customer and provider.

    Direct RTP (no proxy)- Bypass ConnexCS, so media flows directly between the customer and carrier.

    Zone (recommended)- Select any of the regional servers

    • Disabled- never record calls
    • 1% Sampling
    • 5% Sampling
