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.

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 concurrent calls per trunk.
