Twilio SIP & PSTN Setup
Budget: $8 – $15 USD
I need clear, actionable guidance to get Twilio handling calls over both SIP and the traditional PSTN network. My immediate priority is a working SIP-to-SIP connection, but I also want to understand how the same configuration can be extended to SIP-to-PSTN and PSTN-to-SIP scenarios.
Here’s what I’m looking for:
• A short comparison of the main approaches Twilio supports for SIP connectivity, including any trade-offs that matter for small-scale deployments.
• A step-by-step walkthrough that takes me from a fresh Twilio account to a live SIP-to-SIP call, with call forwarding enabled in the flow.
• Quick notes on what changes (if any) are required to add PSTN in/out calling later.
Keep the explanation focused on the essentials—Twilio Console, SIP Domains, credentials, and the exact Voice API settings—so I can replicate everything without guessing. Please highlight your relevant Twilio or VoIP experience when you respond; that’s the single most important factor for me.
