Comparisons

Not "X is always better" — which tradeoffs fit which situation.

• Twilio vs. Telnyx for voice AIA working comparison of Twilio and Telnyx as the telephony layer under an AI voice agent — cost structure, routing control, BYO-SIP, provisioning friction, and the account-stability risk that made me move production traffic.
