I've edited out your FPL account for privacy reasons (also, posting your phone number online is a great way to have your phone number added to spam lists).
Note that only one registration per FPL account is allowed at any time. When there are multiple devices/softphones using the same account, only the most recent registration is valid. The previous device will lose registration. This is especially important to consider if someone else is using your SIP credentials (username and password) that are found after logging in at
https://www.freephoneline.ca/showSipSettings (or if you're trying to register your FPL account with a smartphone SIP app or with another device).
Registration is required for incoming calls. It is not required for outgoing calls. If you simply want to make outgoing calls using your FPL number, configure, but don't register the account, on the SIP app being used, with Acrobits Groundwire, for example, on a smartphone (there is no way to do this with the Freephoneline desktop application; the Freephoneline desktop application doesn't offer to option to not register).
1. You need to have purchased a VoIP unlock key for your FPL account (currently $99.95+tax): login at

If you've already purchased a VoIP unlock key, login at
https://www.freephoneline.ca/showSipSettings to see your SIP settings.
2. You also need to download or buy a SIP app on your iPhone (from the App Store) and configure your FPL sip settings in the app. I use Acrobits Groundwire. I don't care which app you use. I may be able to help with questions involving Groundwire, but I probably won't be willing to assist with answering questions about other apps (since I'd have to spend my own time downloading and learning the other app). Acrobits Groundwire currently costs $13.99+tax (when it's not on sale). Again, there are other SIP apps you can use that are cheaper. Some are free. Out of the SIP apps I've tried, I prefer Groundwire, especially because I don't need to pay ongoing subscription fees to use a Push server.
However, there's a drawback with push notifications in that your (Freephoneline) SIP credentials are essentially being given to Acrobits, in this example, in order for them to register your SIP username and password on their proxy server so that you can receive push notifications from them. While Acrobits is reputable, giving another service your SIP username and password is a potential security issue. That said, they've never had a security breach. Unlike other SIP app devs, Acrobits, Groundwire’s developer, can give you the software to admin your own SIPIS server, where you live, if you're willing to put in the work and keep a server running 24/7:
https://doc.acrobits.net/sipis/installation.html (I'm not going to assist with that). And, in that case, using Groundwire's Push server is not all that secretive and spooky. To use Push with Bria (or Zoiper), you'd be paying ongoing subscription fees (and the same concern applies, insofar as you're giving your FPL credentials to a third party; that's true whenever you use Push, regardless of the SIP app being used).
Groundwire also supports handoffs during calls between cellular data and Wi-Fi without call drops, unlike some other SIP apps.
I'm NOT advocating that you purchase Groundwire. You can choose to use whatever you want.
If you want a free or cheaper, less complicated, solution, you can use Fongo Mobile:
https://www.fongo.com/fongo-mobile/. However, you'll have to use a different phone number since FPL accounts and Fongo Mobile accounts are separate, unless you port your FPL number to Fongo Mobile:
https://support.fongo.com/hc/en-us/arti ... Home-Phone. If you port your number away from Freephoneline, you'll lose your FPL account automatically once porting is completed. I'm not sure what the fee for porting from FPL to Fongo Mobile is currently, but it used to be $5+tax. The fee now appears to be $25+tax (or at least, I can no longer find evidence of the fee being $5 when porting away from FPL to Fongo Mobile). For more information about porting, submit a ticket:

Freephoneline does not support SMS (texting). Fongo Mobile does. Receiving incoming texts to Fongo Mobile is free with some exceptions:
