Getting Started

Configuring or Accessing the Features/Settings on NexusUC

This guide covers the setup and configuration of all major NexusUC features. Use the table of contents on the left to jump directly to the feature you need.

Before configuring your PBX, refer to the recommended extension number ranges below to keep your system organized:

Range Category
3000 – 3999 Conferences
4000 – 4999 Fax Servers
5000 – 5999 IVR Menus
6000 – 6999 Ring Groups
7000 – 7999 Call Center Queues
8000 – 8999 Time Conditions
9000 – 9999 Call Flows

Set up New Extensions

Extensions are the foundation of your PBX — each one represents a phone line assigned to a user or device. You'll need to create extensions before configuring other features like ring groups, queues, or call forwarding.

  1. Navigate to Accounts → Extensions.

    Extension

  2. Click on the +ADD button to open a new extension add form.

    Extension

  3. Assign an appropriate extension number and link it to the relevant user.

    Extension

  4. Set the caller ID fields:

    • Effective Caller ID Name and Number — used for internal calls
    • Outbound Caller ID Name and Number — displayed for external calls

    Extension

  5. Configure the Voicemail settings (optional):

    • To forward voicemails to email, enter the address in the Voicemail Mail To field and enable Audio File Attachment
    • To retain voicemail recordings on the local device (phone), set Voicemail Keep Local to True; otherwise, leave it as False (default)

    Extension

  6. Enter a suitable descriptive name for this extension (e.g., 100 - Test), then click Save at the top right of the page.

    Extension

    Extension

Result: Once the new extension has been successfully created, it will appear under Accounts → Extensions. You can assign this extension to any inbound destination action.

Extension

Set up and Attach Devices

Device provisioning allows you to link physical IP phones to extensions, so they automatically register and receive configuration updates from the PBX.

  1. Attach a device's 12-digit MAC address to the new extension to be auto-provisioned. Select the appropriate model from the template dropdown if available (e.g., Yealink IP deskphones or cordless handsets).

    Devices

  2. Once the above details are added and saved, the device will automatically appear under Accounts → Devices.

    Devices

  3. Under the PROFILES section, create a device profile to configure:

    • Manual Call Flow Diversion Switch BLF keys
    • Speed-Dial buttons on the phone screen

    This allows users to easily toggle night switches or quickly dial specific extensions or external numbers directly from the phone.

    Devices

    Profile key configuration screen:

    Devices

    Example of configured BLF and speed-dial keys:

    Devices

  4. To display these keys on the phone screen, assign the created profile to each device. Navigate to Accounts → Devices, select the appropriate device, choose the correct profile from the dropdown menu, and click Save.

    Devices

Note

If you make any changes to a profile, each phone using that profile must be re-provisioned for the updates to apply. Click the Provision button at the top right to push changes to the device. If changes don't reflect after provisioning, try rebooting the phone. If that still doesn't work, perform a factory reset to apply the new settings.

To register Yealink handsets via RPS, go to Applications → Yealink RPS.

Note

If this is the first time, you may need to add your domain to the RPS server (as shown below).

Devices

Once done, you'll see the newly attached Yealink devices listed. Click the '+' icon next to the relevant device to add it to the RPS server (the icon will change to a '–' to indicate success). Once added, perform a factory reset manually on the handset to complete registration.

Warning

Please allow 10–15 minutes for the factory reset or firmware updates to complete.

Result: Once the devices are registered, they will appear in the list as shown below.

Devices

You can also view registered devices under Status → Registrations.

SIP Endpoint Registration Options for NexusUC Domains

Localcom provides three methods for registering SIP endpoints depending on how NexusUC is deployed and where the devices are located.

1. DNS SRV (Internal Device Registration — On-Prem PBX)

When to Use:

  • For locally installed On-Premise PBXs hosted NexusUC instances
  • When a partner installs NexusUC on a local PC
  • When using Localcom-provided mini-PCs

Configuration: Under Accounts → Devices → Selected Device

  • Transport = DNS SRV
  • Port = 0

Devices

2. Proxy Port (External Device Registration — Remotely Hosted NexusUC)

When to Use:

  • For remotely hosted NexusUC instances (e.g., installation on a Virtual Private Server)
  • Commonly used for VPS deployments

Configuration:

  • Proxy Port: Can be obtained from the NexusUC service page in the portal (added by default to the device page)

Devices

  • If the proxy port is not auto-filled, manually enter it under Accounts → Devices → Selected Device:
    • Transport = TCP/UDP (Standard)
    • Port = Proxy Port

Devices

The system is programmed to auto-setup the proxy port by default.

Example of proxy registration on MicroSIP:

Devices

3. Custom FQDN Registration (Custom Domain Name)

When to Use:

  • For partners who do not want to use the default domain (uc.localcom.com.au)
  • Allows using a custom domain instead (e.g., mypbx.example.com.au)
  • The NexusUC instance must be hosted remotely

Configuration:

  • Transport: TCP/UDP (standard)
  • Port: 5060
  • Domain: Partner's custom domain (configured on NexusUC)

Note

Custom FQDN registration does not rely on a proxy.

Devices

Set up Inbound and/or Outbound Destinations, Time Conditions, and Call Flows

Destinations define how incoming and outgoing calls are routed through your PBX. Combined with Time Conditions and Call Flows, they form the backbone of your call routing logic.

  1. Navigate to Dialplan → Destinations.

    Destination

  2. Select either the Inbound or Outbound button, followed by the +ADD button to add a new destination.

    Destination

  3. Specify the destination type (Inbound or Outbound) and enter the Destination DID number.

    Destination

  4. Assign an action for the Inbound Destination. This can be any of the following:

    • Extension
    • Call Center Queue
    • Time Condition
    • Manual Diversion Call Flow Switch
    • Ring Group
    • IVR Menu
    • Outbound Destination

    You can also choose to play custom hold music or use the system default, and enable or disable call recording for that destination.

    Destination

Tip

You may define a Caller ID Name Prefix to help users identify the origin of calls — especially useful when handling calls from multiple site locations. The prefix displays on the phone screen before the caller ID number (e.g., Sydney#0400123123).

For a robust inbound call routing setup, follow this recommended configuration:

  1. Create Holiday and Business Hours Time Conditions under Applications → Time Conditions.

    Destination

    Holiday Time Condition setup:

    Destination

    Business Hours Time Condition setup:

    Destination

    Destination

  2. Create an Emergency Contact Diversion (mobile or DID number) under Dialplan → Destinations (Outbound).

    Destination

  3. Set the Main Inbound Action (e.g., Extension, Ring Group, Queue, or IVR Menu) on the Business Hours Time Condition.

    Destination

  4. Assign the Business Hours Time Condition as the Alternate Destination under the Holiday Time Condition.

    Destination

  5. Assign the out-of-office destination (e.g., Voicemail Inbox or Diversion mobile/DID number) as the Alternate Destination under the Business Hours Time Condition.

    Destination

  6. Create a Manual Diversion Call Flow Switch for emergency failover under Applications → Call Flows.

    Destination

    Destination

  7. Configure the Call Flow with the following assignments:

    • Destination Label: Undiverted (or anything sensible)
    • Destination: Holiday Time Condition

    Destination

    • Alternate Label: Diverted (or anything sensible)
    • Alternate Destination: Emergency Contact Diversion (mobile/DID)

    Destination

    Destination

  8. Assign the Manual Call Flow Diversion Switch as the Main Inbound Action for the Inbound DID number.

    Destination

Set up Ring Groups

Ring Groups allow multiple extensions to ring simultaneously or in sequence when an inbound call arrives. This is useful for teams or departments where any available member should be able to answer.

  1. Navigate to Applications → Ring Groups.

    RingGroup

  2. Click on the +ADD button to open a new Ring Group add form.

    RingGroup

  3. Specify a clear and descriptive name for the Ring Group along with its standard category extension. You may also attach a greeting that will play when an inbound call reaches this Ring Group.

    RingGroup

  4. Select the ringing strategy for the Ring Group:

    RingGroup

    Strategy Description
    Simultaneous Rings all destinations. All destinations share the same thread.
    Sequence Calls destinations in sequence, lower order goes first.
    Enterprise Rings all destinations. Each destination uses its own thread.
    Rollover Calls destinations in sequence and skips busy destinations.
    Random A random destination will ring.

  5. Define the destinations that should ring (internal extensions or external phone numbers). Set the call timeout duration (in seconds) and choose a timeout destination (where the call goes if no one answers).

    RingGroup

  6. Set the Ring Back to au-ring — this is the sound the caller hears while waiting (typically a music on hold or ring back tone).

    RingGroup

  7. Additional optional settings are available for further customization:

    RingGroup

    • Caller ID Name — The Caller ID name used for outbound external calls
    • Caller ID Number — The Caller ID number used for outbound external calls
    • Distinctive Ring — Have a distinctive ring tone for inbound calls to this Ring Group
    • Call Forward — Enable or disable following the call forwarding setting of a destination in the Ring Group
    • Follow Me — Enable or disable the Follow Me feature of a destination in the Ring Group
    • Missed Call — Enable missed call notifications to be sent to a specified email address
    • Ring Group Forward — Enable or disable Ring Group call forwarding and specify an alternate destination

    RingGroup

Result: Once the new Ring Group has been successfully created, it will appear under Applications → Ring Groups. You can assign this to any inbound destination action.

RingGroup

Set up Call Center Queues and Agents
