AI agents for voice & telephony

Phone isn't going away, especially in the U.S.

Phone is where customers turn when things get complex, urgent, or high-value. CX AI agents can make and answer calls, handle transactions, access your systems and resolve issues in real time and at scale. When needed, a human takes over seamlessly.

Interactive demo

Remind, resolve, collect, do business — inside the thread.

Your customers or internal users can send or reply to a message and handle everything within your business workflow, without leaving the conversation.

Real-time API requests, complex flows, and file sharing — all native. And when things get complicated, a human can seamlessly take over the conversation, or hand it back to AI.

The telecom piece

In front of your IVR, behind it, or instead of it.

Most voice AI vendors hand you an API and wish you luck with your carrier. We are also a contact center operator. SIP trunks, PBX, SBCs, AMD, routing, and everything else that makes voice work reliably are our day job.

SIP trunk termination

TLS and SRTP, registration or IP authentication.

Pay as you go

You only pay for the exact time (fractional minutes) the AI agent spoke. No answer, no cost.

Outbound dialing

Volume is not a constraint, whether we bring the carrier or sit on yours. Twenty concurrent channels is where most accounts start, and we open it as far as your traffic requires.

Smart routing

Whether by design in the flow or because a failover tripped, calls can go where you decide: a human queue, a specific extension, or back into a legacy IVR.

Observability

Processed data lands the moment a call ends, and campaign progress is visible while it's still running.

Why we strive

Most voice AI projects stall on the phone line, not the model.

The demo always sounds good. Most voice models are good enough now, and you could probably build the bot in house. Then the telephony shows up: a cloud PBX that won't accept BYOC, a transfer that drops the customer, a codec mismatch that turns a fast agent into a slow one…

We have run this infrastructure for contact centers since before conversational AI was something you could rent. Proxima CX gets the pipeline working and keeps it that way.

Best-in-class architecture

We are not in the race to build models: CX plugs in whichever one is the most natural, efficient and affordable for the use case, and then handles the other 99 things that make a phone campaign enterprise grade.

Naturality

Dozens of voices to pick from, agents that switch between languages and gracefully handle a customer talking over them. Barge-in, partial-hypothesis handling and seamless re-prompting are default behavior.

Data security

Recordings and transcripts can be pushed straight to your repositories and auto-deleted from ours. The data is yours, and your agent configuration and prompts stay private, never shared. ISO 27001 certified and SOC 2 Type II attested.
