How Switchy teams use it

Starter prompts

@Saperly create a connection named 'Lead Qualifier' that asks callers their company size, current CRM, and timeline for purchase, then thanks them and hangs up.

@Saperly bind connection ID conn_abc123 to number ID num_xyz789 so the 'Support Triage' persona answers calls on our main support line.

@Saperly place a call from number ID num_xyz789 to +15551234567 using connection conn_abc123, wait 15 seconds, then end the call to test our new qualifier script.

@Saperly get the transcript for call ID call_def456 and summarize the key objections the prospect raised during the qualification call.

@Saperly check consent for peer number +15559876543 on our number ID num_xyz789 and tell me if we're clear to call them today.
