Telnyx role-play cheat sheet
For the mock cold call at the end of most SDR interviews.
What they sell, in one line
Phone calling, text messaging and IoT connectivity delivered through developer-friendly APIs on Telnyx's own private global network.
Who you'd be calling
CTOs, engineering leads, product managers and telecom or operations heads at software companies, and startups that build calling or texting into their apps
Your opener
“Hi [Name], this is [You] from Telnyx. I know I'm catching you cold. We give developers phone calling and texting through one API, running on our own private network. Are you building or running anything that sends texts or makes calls?”
Problems you solve for them
- Call quality and reliability suffer on networks owned by someone else
- Messaging and voice costs add up and pricing is confusing
- Juggling several vendors for voice, SMS and IoT is a hassle
Discovery questions to ask
- Which provider handles calls and texts in your product today?
- How happy are you with call quality, delivery rates and cost?
- How much engineering time goes into maintaining your communications setup?
Objections they'll throw at you
“I'm busy.”
→ Understood. I'll be 20 seconds. Who on your team looks after voice and messaging, and when's a good time to catch them?
“Not interested.”
→ No problem. Just to check, is your current communications setup working well and priced the way you want?
“We already use Twilio.”
→ A lot of teams do, and it's a solid product. Some of them also test us for price and call quality. Would a small side-by-side test be worth your time?
“Just send an email.”
→ Sure. What are you using calls or texts for, so I can send the right info instead of a generic pitch?
Competitors worth knowing
Twilio, Bandwidth, Vonage, Plivo
Interview tips for this company
- Learn what an API is, and the difference between voice, SMS and SIP trunking, at a simple level.
- Buyers are technical. Don't bluff. Say 'I'll bring in a specialist for that' when you don't know.
- Be ready to explain why owning a private network matters: quality and control.
