Phone Numbers
A real line for your agent. Provisioned through Telnyx.
Search local or toll-free numbers in the dashboard, buy within your plan’s free allowance (or $5/mo extra), assign one published agent, then go live after playground testing.
Buy. Assign. Answer.
Phone numbers are the bridge between callers and your AI. Wirevox provisions them through Telnyx — then routes every dial to the published agent you assigned.
Map one agent.
Each number routes to exactly one published agent. Draft-only agents stay off the line.
Dial → Telnyx → Wirevox.
Caller audio streams in, the published config runs STT → LLM → TTS, then transcript + post-call.
Numbers page
My Numbers and Buy New.
Two tabs on the Numbers page: inventory with agent assignments, and Telnyx search to provision the next line.
- Countries including US, CA, GB, AU, NZ, DE, FR, IE, NL
- Local area codes or toll-free nationwide numbers
- Smart search: 3 digits = area code; 4+ = contains
- Free allowance by plan, then $5/mo per extra number
Free numbers by plan — then $5/mo.
Paid plans include free lines. Beyond that allowance, each extra number is $5 per month on your subscription.
STARTER
1 free number
Unlock telephony on a paid plan, buy your first line within the free allowance, assign a published agent.
GROWTH
3 free numbers
Separate lines for locations or teams — still one agent per number, with extras at $5/mo.
AGENCY
5 free numbers
More inventory for client workspaces. Free-tier and PAYG cannot purchase numbers until they upgrade.
Inbound lifecycle
What happens when someone dials.
Every inbound call follows a fixed path: Telnyx receives the dial, Wirevox answers and streams media, the published agent config runs the voice pipeline, then the call ends with transcript and post-call analysis.
01 / DIAL
Caller hits your #.
Telnyx sends the webhook with caller ID, dialed number, and call control.
02 / RESOLVE
Find the agent.
Wirevox looks up the assignment and loads the published version — not your draft.
03 / PIPELINE
STT → LLM → TTS.
Media streams over WebSocket. Tools assemble; barge-in clears Telnyx audio so interruptions feel instant.
04 / CLOSE
Transcript + analysis.
Hangup saves the transcript, runs post-call enrichment, and can fire call.ended webhooks.
Assignment rules
Routing that stays predictable.
Numbers only go live when the agent is publish-ready. Reassignment pauses the previous agent so two configs never fight for the same line.
01
One-to-one mapping.
Each number assigns to exactly one agent; each agent has at most one number.
02
Published agents only.
You cannot assign a number until the agent has a published version. Live calls always run that snapshot.
03
Same workspace.
The agent must belong to the same workspace as the number.
04
Barge-in clears playback.
When the caller interrupts, Wirevox sends a clear event to Telnyx so buffered audio does not keep talking over them.
05
Test first, then go live.
Use playground or Test Call in the browser — no number required — then buy and assign when the draft is ready to publish.
— On the line
Telephony details that matter in production.
Telnyx end to end
Number orders, call control, WebSocket media streaming, and SMS all run through Telnyx.
Confirm mid-call
Send appointment confirmations or links with send_sms while the caller is still talking — on SMS-enabled numbers.
30-day reservation
Release a number and it stays reserved for reclaim — it does not route calls until you reactivate it.
