The Phone Numbers page is your number inventory: what you own, what each number is used for, and how healthy it is.

​
Your inventory

The Numbers tab lists every number on your account with its type and status:
  • Type — inbound (attached to an agent that answers it), outbound (used as caller ID for outgoing calls), or idle (owned but unassigned). Stat cards at the top show the split.
  • Status — whether the number is active, paused, or has a problem.
  • Agents assigned — which agents use the number.
Per number you can view history (call activity and assignment changes over time, also available on the Histories tab) and release a number you no longer need — releasing frees it permanently, so it asks for confirmation.

​
Getting numbers

There are two paths:

​
Buy a number in the dashboard

The Buy Numbers tab lets you search available numbers by country and pattern, see the price, and purchase directly. Purchased numbers appear in your inventory immediately and can be assigned to agents.

​
Bring your own carrier (SIP)

If you already have numbers with a telephony carrier, connect them over SIP — your DIDs stay with your carrier and route calls to OSVI agents. Step-by-step guides per carrier:

Plivo

SIP trunk over Plivo’s global network.

Ozonetel

SIP integration for Ozonetel numbers.

Exotel

SIP or Voicebot WebSocket streaming.

Vobiz

SIP trunk over Vobiz infrastructure.

​
Inbound vs outbound

  • Inbound — attach a number to an agent and the agent answers every call to it. Inbound campaigns additionally track missed calls on their numbers.
  • Outbound — campaigns and API calls place calls using your outbound numbers as the caller ID.
Keep at least one number per direction and avoid sharing a high-volume campaign caller ID with your inbound support line — recipients who call back a campaign number should reach an agent prepared for that conversation.
