Creating a New Trunk Group

Step 1. Under the “Trunks” section, select “Voice Trunks”, click the “+Add new” button and choose “Trunk Group” option (Fig. 1).

Step 2. Select trunks that should be included into the Trunk Group and enter “Friendly name” (Fig. 2).

  • Friendly name – name to identify created trunk group on your DIDWW user panel.
  • Capacity Limit – maximum number of simultaneous calls for the trunk group.
  • Choose trunks – trunks that being included into Trunk Group (can be selected up to 10 voice trunks).
  • Map all DID(s) – if checked, all DIDs on your account will be assigned to this Trunk Group.

Step 3. Click “Submit” to complete trunk group configuration (Fig. 2).

Step 4. Define Priority and Weight values and this way distribute load between multiple destinations (Fig. 3).

An alternative way defining advanced distribution parameters is by editing voice trunks under group and completing the following fields under spreaded “Trunk group configuration” (Fig. 4).

  • Priority – the priority of this target trunk. DIDWW will attempt to contact the target host with the lowest-numbered priority it can reach. The range is 0-65535.
  • Weight – a trunk selection mechanism. The weight field specifies a relative weight for entries with the same priority. Larger weights will be given a proportionately higher probability of being selected. The range of this number is 0-65535.
  • Ringing Timeout – timer after which it will be end transaction with internal disconnect code “Ringing timeout” if the call was not connected.
  • Available Re-routing Disconnect Codes – SIP disconnect Codes for which DIDWW will NOT attempt next voice trunk.
  • Re-routing Disconnect Codes – disconnect codes on receipt of which we will continue rerouting of calls using the additional trunks in a trunk group.
  • Use default Re-routing Disconnect rules – enables set re-routing configuration.


created trunk group is assigned to DID number(-s) in the same way as regular Assigning a Voice Trunk.
