Your numbers, your carrier.
Drellia voice agents place and answer calls over a standard SIP trunk. Keep the carrier you already have, or let us provide the line.
- Self-serve
Bring your own SIP trunk
Add your trunk in the app yourself: username/password or IP authentication, UDP, TCP or TLS transport, G.711 codecs, caller ID and allowed countries.
-
Twilio Elastic SIP Trunking
Point a Twilio Elastic SIP trunk at Drellia and use your Twilio numbers for inbound and outbound voice-agent calls.
-
Carrier trunking
Connect a trunk from your telecom carrier. Drellia gives you a fixed IP address to add to your carrier's allow list.
-
Inbound and outbound
Run outbound campaigns and let voice agents answer inbound calls on your numbers, with transfer to a human when needed.
-
Several trunks, one account
Add more than one provider, choose a default, pick the trunk per campaign and cap simultaneous calls per trunk.
- On request

WhatsApp alongside voice.
Conversations on WhatsApp are handled and audited with the same questionnaires as your calls.
- Set up with our team
WhatsApp Business
AI agents answer inbound WhatsApp messages through the WhatsApp Business Platform, and voice agents can send the customer a payment link by WhatsApp during a call.
-
Team alerts by email
During a call, a voice agent can email your team (for example, when a customer wants to pay) so a person follows up.
Automate with the public API.
A documented REST API with API-key authentication. Use it to feed calls in for auditing and to trigger voice agents from your own systems.
Read the developer docs-
Send calls for AI auditing
Create conversations from your dialer or recording system and upload the audio or the transcript, so every call is evaluated against your questionnaires.
-
Trigger calls and campaigns
Start a voice-agent call or work with campaigns straight from your CRM or back office.
-
Keep your data in sync
Manage customers, employees, departments and questionnaires through the API.
-
Exports
Export evaluations and campaign calls to CSV or Excel for your own reporting.
-
Knowledge files
Upload documents such as PDF, Word or spreadsheets so your agents answer from your own policies and scripts.
- On request
