Telephony for your bot

Receive calls.
Bring in your team.

A SIP trunk connects the telephone network to a voice agent. A customer calls your company number, and the bot receives the call and responds using the configured call flow.

  • Connect an existing bot or launch a new project.
  • Inbound and outbound calls to agreed destinations.
  • Transfers to a staff member when human assistance is needed.

Architecture without unnecessary complexity

How a call works

For an inbound call, the number receives a call from the telephone network and forwards it to the agreed SIP address.

01

Phone number

The customer dials your familiar company number.

02

Stream Telecom

The call is directed to the agreed SIP route.

03

Your AI agent

The platform recognizes speech, generates a response, and speaks it aloud.

04

Staff member

When needed, the call is transferred according to the configured call flow.

For outbound calls, the direction is reversed: AI platform → SIP trunk → customer’s phone. Outbound calling availability and the displayed number are agreed separately.

What matters before launch

What the connection includes

Inbound and outbound calls

We will define call destinations, number formats, and permitted Caller ID.

Capacity for your workload

We will agree on the number of concurrent conversations and the rate of new call attempts — CPS.

Two-way audio

We will check compatible codecs and media flow so both parties can hear each other.

Transfer to a human agent

We will choose a transfer mechanism: SIP REFER or a connection through a PBX, if supported by the setup.

Connection security

We will agree on authentication, IP-based access, and TLS/SRTP availability on the required segments.

Fallback scenario

We will define what happens when the destination is busy, times out, or is unavailable over SIP.

Failover and transfers

Who will answer the customer
if the bot is unavailable

We will discuss a fallback destination: a staff member, a PBX queue, or another available handler. Trigger conditions are checked using test calls.

The bot did not accept the call

Routing can respond to agreed SIP errors or a timeout and select a fallback destination.

The customer needs a human

The AI platform’s call flow initiates the transfer. Sending the conversation transcript or CRM data to a staff member requires a separate integration.

The AI made an error during the conversation

Telephony does not assess the meaning of the bot’s response. Handling these situations is configured in the agent’s logic.

Stream Telecom voice agents

We will connect your existing bot or help launch a new one

We will select a telephone connection, call flows, and the integrations your business needs.

New project

Launching a voice agent

We will define which questions the agent answers, what data it needs, and when it transfers a call to a staff member. We will agree on the scope of work and pricing.

Already have a bot

SIP connection

We will check your bot’s interface and connect it to the telephone network. We will configure numbers, call destinations, and routes.

Working with your team

Connection to your PBX

We will agree on transfers to staff and queues. If needed, we will configure CRM data exchange separately.

What we check together

What we check before launch

Routes Inbound and outbound calls, the correct destination number, and Caller ID.
Audio Voice in both directions, agreed codecs, NAT, and RTP.
Load Concurrent conversations and the rate of new calls within the agreed limits.
Transfers The call reaches a staff member; busy and no-answer behavior is clearly defined.
Failure Disconnecting the primary destination triggers the expected fallback scenario.

Pricing for your configuration

How much does
a SIP trunk connection cost

To prepare a quote, we need your platform, calling countries, call volume in minutes, and peak number of concurrent conversations.

What the price includes

  • Setup and recurring fees for a number, if required.
  • SIP connection parameters and agreed capacity.
  • Calls to selected destinations.
  • Additional routing and integration work — as agreed.

Voice agent, call flow, and integration costs are listed separately from the number and calls. We will agree on the solution scope and final quote before connection.

Answers before you connect

Frequently asked questions

It is a SIP connection between telephone infrastructure and a voice bot system. It routes phone calls to an AI platform and, when outbound calling is agreed, allows the agent to make calls.

A number is the address customers use to call your company. A SIP trunk is the connection that carries the call to the bot or PBX. Multiple numbers can share the same connection setup.

Yes. We will discuss the agent’s tasks, call flows, telephone connection, and required integrations. We will agree on the solution scope, timeline, and pricing before work begins.

The AI platform name, calling countries and destinations, required numbers, approximate call volume in minutes, peak number of concurrent calls, and requirements for transfers to a human agent.

This depends on the AI platform and telephony capabilities. Possible setups include SIP REFER or a transfer through a PBX. Before launch, the entire route and billing conditions for additional call legs are checked.

The agreed setup can include a fallback destination triggered by a timeout or SIP error. The agent platform must detect and handle logic or AI model failures within an accepted call.

No. Total latency includes the network, speech recognition, model processing, and speech synthesis. The entire conversation needs to be tested, rather than just the telephone connection.

A SIP trunk provides a telephone connection. Agent development, its AI platform, and integrations are quoted separately if required.

This depends on the number, current operator, and setup. Number porting, call forwarding, or a connection through an existing PBX are checked; costs and limitations are compared before launch.
