Hi there! I understand you're trying to set up call forwarding in the CaptionCall app but noticed the phone number for call forwarding is missing. Let's see if I can help you get that sorted.

Could you tell me a bit more about what you see in the app? For example, do you see a section or option called "Call Forwarding," but no phone number appears, or is the forwarding option itself missing? Also, are you using the CaptionCall Mobile app on your Macintosh through some compatibility layer or browser, or is this related to your regular phone line?

Generally, for CaptionCall Mobile, the call forwarding setup involves enabling the feature in the app, which then gives you a code to dial from your phone to forward calls to CaptionCall. This means the forwarding number itself might not be directly visible; instead, you activate forwarding by dialing a code the app provides on your phone system.

Here’s a simplified way to set it up if the forwarding number is not shown:

1. Open the CaptionCall Mobile app on your device.
2. Open the side menu and find the "Call Forwarding" option.
3. Tap "Enable" or "Turn On" call forwarding.
4. The app should display a code (usually something like *72 plus a number). You need to dial this code from your phone you want to forward calls from.
5. After dialing the code, your phone calls will be routed to CaptionCall, where you get captioning.

If the forwarding number or code does not show up at all, it could be an app issue or a settings glitch.

To try next:

- Make sure the CaptionCall Mobile app is up to date.
- Restart the app and your device.
- Confirm that your device has a working internet connection.
- If you have access to a mobile phone line or landline you want to forward from, try checking your phone’s own call forwarding settings to ensure it is possible to set forwarding out.

If you've already tried these and still see no forwarding number or code, I can guide you toward advanced troubleshooting or have a support team member assist further.

Does that description match what you're seeing? Let me know where you are stuck or what screen looks like, and we'll continue from there.
