Phone Numbers

Buying a new number

Connecting your own Twilio account

  1. 1Open Settings → Integrations → Twilio
  2. 2Paste your Twilio Account SID and Auth Token
  3. 3Click Connect — Talknex will validate your credentials
  4. 4Your existing Twilio numbers will appear under Phone Numbers → Imported
  5. 5Assign each number to an agent

SIP trunking

For carriers outside Twilio, or enterprise networks with existing PBX infrastructure, SIP trunking lets you forward calls to Talknex over SIP.

# Point your SIP trunk to:

sip.talknex.ai:5060

# Authenticate with:

Username: <your-org-id>

Password: <sip-credential from Settings → Phone → SIP>

SIP trunking is available on Fully Managed. Contact sales for setup assistance and compliance documentation.

WhatsApp Business

The same agent that handles phone calls can also handle WhatsApp conversations (text and voice notes). Connect via your Meta Business Manager account.

WhatsApp is available on Fully Managed. The agent uses the same system prompt and knowledge base — you only need to enable the channel in Settings → Channels → WhatsApp.

Call routing rules

Each phone number can have routing rules that determine which agent answers based on time of day, caller ID, or IVR input.

Business hours

Route to primary agent 9am–6pm Mon–Fri; voicemail otherwise.

Caller ID match

Route VIP callers (by number or CRM tag) to a dedicated agent with priority queueing.

IVR keypad

Play a short menu ("Press 1 for sales, 2 for support") and route accordingly.

Overflow

If all concurrent slots on Agent A are busy, overflow to Agent B.
