Keep your dialer. Add AI voice agents.
If your contact centre already runs a dialer, you can keep it. Your dialer places the call and manages pacing, and when the customer answers, the call goes to the SquadStack.ai agent over SIP or as an audio stream. Outcomes, recordings and transcripts come back to your system.

- No SIP channels needed
- Lower cost and lower latency
- Needs a dialer that supports audio streaming

Certificates and security reports on our Trust CenterFrequently asked questions
Can I keep my existing dialer and add an AI voice agent?
Yes. Your dialer keeps placing calls and pacing leads, and SquadStack.ai handles the conversation once the customer answers.
SIP or WebSocket streaming, which is better?
Streaming is cheaper and has lower latency, so we recommend it when your dialer supports it. SIP handoff works with almost every dialer.
What do you need from our telephony team?
The dialer name and method, SIP trunk details if using SIP, the IPs to allow, and a test campaign with a few test leads.
Can the AI transfer calls back to our agents?
Yes. On your own SIP setup the transfer is a cold transfer today, and the outcome and transcript reach your system after the call.
Is SIP trunk integration available for AI voice agents in India?
Yes. We accept SIP transfers from your dialer or SBC, with lead details carried in SIP headers.
