Outbound Trunks

DIDWW’s Outbound SIP Trunking service is delivered in partnership with selected, global incumbent local exchange carriers (ILECs). This service exclusively uses premium routes to ensure cost-efficient calling with the highest level of audio quality.

Key Features

  • Unlimited Concurrent Call Capacity: Scalable network with outbound SIP trunks providing unlimited concurrent call capacity. Users can add as many trunks as required to support their specific communications model or customer base.

  • Configurable Caller ID: Select the caller ID displayed to call recipients. Options include local, mobile, toll-free, and short numbers.

  • Call Filtering: Restrict outbound calls and prevent undesired traffic by enabling call filtering on a per-trunk basis. Tools include username and IP address authentication, white lists, and black lists.

  • Call Routing and Restrictions: Apply fully customizable dial plans and routing rules on a per-trunk basis. Enforce destination restrictions and manage re-route SIP codes for calls to destinations like international or premium toll-free numbers.

  • Monitoring and Security: Monitor activities with per-trunk CDRs and leverage DIDWW’s proactive fraud monitoring platform to detect and alert about suspicious calling activities.
