Act mid-call.
Check availability, create a lead, or transfer when the prompt and tools say it’s time.
Custom Functions
Mid-call actions. Real systems.
Functions let the agent book, transfer, text, email, gather details, search knowledge, run workflows, or take a message — while the caller is still on the line.
Talk is cheap. Wirevox executes.
Eight function categories on the Functions page — from CRM calendars to take-a-message — assembled into tools the live agent can call mid-conversation.
Clean spoken data.
Spoken phones and emails become digits and addresses before anything hits your systems.
Shared executor.
Leads sync, outcomes prioritize, credits deduct, and destination webhooks fire after the tool runs.
Live call workflow
One call. Full chain.
Availability, booking, SMS confirmation, CRM update, then a call summary — the mid-call path functions are built for.
- Calendar book / cancel / reschedule on Google or Outlook
- Jobber, Clio, Filevine, and Open Dental actions
- SMS and email confirmations with optional templates
- Cold transfer via Telnyx; warm agent handoff with transcript context
Eight categories. Clear jobs.
Every function you attach maps to a category on the Functions page — integrations, transfer, confirmations, gather, knowledge, workflow, or take a message.
INTEGRATIONS
CRM & calendar tools
Generated from connected workspace providers — only tools whose integrations are still connected stay available.
TRANSFER
transfer_call
Bridge the caller to a real PSTN number via Telnyx. AI pipeline stops so AI cost freezes at handoff.
CONFIRM
SMS & email
send_sms_confirmation and send_email_confirmation — optional templates with bracketed variables filled mid-call.
GATHER
system_infolist
Save name, phone, email, reason, plus custom fields you define for the lead record.
KNOWLEDGE
Scoped search
Named tools that search selected docs instead of the whole knowledge base.
WORKFLOW
Conversational SOP
Inject a named graph / state-machine prompt so the agent follows a defined path.
MESSAGE
take_message
Collect caller name, phone, message, urgency, and optional recipient for the team.
Connected providers
Integrations that become tools.
Once a provider is connected in the workspace, its enabled actions assemble into tools the agent can call — orphan tools for disconnected providers are stripped automatically.
CALENDAR
Google Calendar+Outlook CalendarCheck, book, lookup, cancel, reschedule.
SERVE
Jobber+Open DentalLeads, requests, patients, appointments.
INTAKE
Clio+FilevineCreate intake and grow leads.
Runtime safeguards
Assemble. Normalize. Execute.
Before a tool ever runs, Wirevox filters disconnected integrations, cleans spoken contact details, and — on warm agent transfers — packs the last transcript lines into a handoff token.
01 / ORPHAN FILTER
Strip dead tools.
If Google Calendar or Jobber is disconnected, those tools never reach the live model.
02 / NORMALIZE
Spoken → structured.
“Five five five…” becomes digits; “name at domain dot com” becomes an email. Incomplete emails are rejected so the agent asks again.
03 / HANDOFF
Warm transfer context.
Warm agent transfers save the last 15 transcript lines and pass an X-Wirevox-Handoff token so the next agent resumes with context.
Core tools
Always available — no external API required.
These built-in tools ship with the platform. Attach them from the Functions page and reference them in the prompt when the agent should use them.
01
transfer_call
Shut down AI services and bridge the caller to a 10-digit / E.164 phone number via Telnyx.
02
system_infolist
Write caller details to local leads — name and phone required, plus optional email, reason, and custom fields.
03
send_sms_confirmation
Text the caller mid-call with a message (and optional template) through Telnyx messaging.
04
send_email_confirmation
Send a confirmation email with subject and body while the conversation continues.
05
take_message
Log caller name, phone, message, urgency, and optional recipient for the business owner.
