固定Google Voice转发号码方案咨询（关联Tasker脚本需求）

Got it, let's break down how to solve this problem— I've run into similar Tasker + Google Voice headaches before, so here's what works:

First, let's address the core issue: Google Voice uses dynamic relay numbers when forwarding SMS to your personal phone, which breaks your Tasker trigger tied to a specific number. Unfortunately, Google doesn't let you "lock" this relay number directly, but we can work around it by adjusting your Tasker logic instead:

• Trigger on SMS content instead of sender number: Google Voice's forwarded texts almost always include a header like [Google Voice] From {original-number}: {message}. In Tasker, change your trigger from "Received SMS from specific number" to "Received SMS containing text" and use [Google Voice] as the keyword. Then, add a Tasker action to extract the original sender number from the message body (using regex like From (\d+): would work) and run your original script logic based on that extracted number. This way, the dynamic relay number doesn't matter anymore.

• Double-check Google Voice settings: Make sure you're using the official "Forward messages to linked numbers" setting in Google Voice (not third-party forwarding hacks). Sometimes, using outdated or unofficial forwarding methods can cause more variable sender IDs. Go to Google Voice web > Settings > Messages > Check "Forward messages to linked numbers" and confirm your personal number is listed there.

If adjusting Tasker logic isn't enough, here are reliable alternatives that let you control the forwarding number:

• Twilio: Grab a free Twilio phone number, then set up Google Voice to forward all incoming SMS to this Twilio number. Next, configure Twilio's SMS forwarding to send messages to your personal phone using the fixed Twilio number as the sender. Your Tasker script can then trigger on this static Twilio number, and you can still keep your personal number private. Twilio has a free tier that works for most casual use cases.

• Local SMS Forwarding Apps: Install an app like SMS Forwarder+ on your phone (where you have the Google Voice app installed). Instead of relying on Google Voice's cloud forwarding, let this app monitor incoming SMS in the Google Voice app, then either:

  • Forward them to your personal number using a fixed sender ID (some apps let you customize this), or
  • Trigger your Tasker script directly from the app, bypassing cloud forwarding entirely. This keeps everything local and avoids dynamic relay numbers.

• IFTTT Applets: Set up an IFTTT applet that triggers when Google Voice receives an SMS, then uses IFTTT's SMS service to send the message to your personal phone. IFTTT uses a fixed sender number for its SMS notifications, so your Tasker script can reliably trigger on that number. Note that IFTTT has a monthly limit on free SMS, so this is better for low-volume use.
