1 import { SignalWire } from "@signalwire/realtime-api";
2 
3 const client = await SignalWire({ project: "ProjectID Here", token: "Token Here" })
4 
5 const voiceClient = client.voice;
6 
7 // Listen for incoming calls
8 await voiceClient.listen({
9   topics: ["office"],
10   onCallReceived: async (call) => {
11     console.log("Call received");
12     // Answer the call
13     call.answer();
14 
15     // Send DTMF tones to the Inbound leg of the call
16     await call.sendDigits("123")
17     console.log("DTMF tones sent!");
18     call.hangup();
