You posted in someone's thread from 2019 where the issue was resolved. I've moved your post to its own thread.

You shouldn't have to unless the ATA isn't being assigned a LAN IP by the router. If you're able to log in to the ATA, that's not the problem.
Dial ***
Then dial 02.
If you're able to login to your ATA using a web broswer with that IP address, the problem has nothing to do with whether a dynamic or static IP address has been assigned to your ATA.
Please follow the steps carefully down the list.
1. a) Dial *79 to ensure that Do Not Disturb is disabled in your ATA.
b) Check all phone cords connected to the ATA to ensure they are not loose or defective.
c) Check to ensure that the phone's ringer is turned on.
2. Login at
https://www.freephoneline.ca/voicemailSettingsa) Ensure that Rings before Voicemail is greater than 1
3. Your ATA's firmware is outdated. Grandstream firmware can be found at
http://www.grandstream.com/support/firmware. I will not be held responsible for failed firmware updates.
https://firmware.grandstream.com/Releas ... 0.33.4.zip4. What brand and model modem are you using?
If you are also using your own separate router in addition to the one supplied by your ISP (which you appear to be doing), then you should be enabling bridge mode instead in the modem/router combo, gateway, or hub issued by your ISP, unless you were given a plain modem (and not a modem/router combo, gateway, or hub). Contact Videotron if required.
5. In your router, ensure that SIP ALG is disabled. Contact Videotron if they gave you your router. With some routers, the the capacity to disable it may not exist.
I took a quick look through
https://support.videotron.com/_media/do ... -guide.pdf, and "SIP ALG" wasn't listed, but that doesn't necessarily mean SIP ALG isn't on.
6. Login to your ATA, Navigate to the FXS Port you're using for FPL
a) change Primary SIP Server to "voip4.freephoneline.ca:6060" without the quotation marks
(use following settings)
b) NAT Traversal: Keep-Alive
c) SIP Registration: Yes
d) SIP Registration Failure Retry Wait Time: 120 seconds (this is not the same setting for the retry wait time for 403, which should just be left at default)
e) Enable SIP OPTIONS/NOTIFY Keep Alive: OPTIONS
f) SIP OPTIONS/NOTIFY Keep Alive Interval: 20 seconds
g) SIP REGISTER Contact Header Uses: WAN Address
h) Register Expiration should be 60 minutes
i) Use Random SIP Port: Yes
j) Use Random RTP Port: Yes
Save settings.
7. This is always proper device reboot order:
A.Turn off modem, router, and ATA.
B. Turn on modem. Wait for modem to be fully up and running.
Wait for modem to be fully up and transmitting data before turning on router.
C.Turn on router.
Wait for router to be completely up and running.
D. Turn on ATA only after the router is fully up and running.
Reboot devices in that order now.
8. Registration is a requirement for incoming calls but not for outgoing calls.
Login at
https://www.freephoneline.ca/showSipSettingsWhat does "SIP Status" indicate?
Please note that if "SIP User Agent" does not reflect a device you're using, someone else is using your Freephoneline VoIP unlock key.
Only one registration is permitted at any time per Freephoneline VoIP unlock key. You can not register the same FPL account on two (FXS) lines simultaneously. Registration is a requirement for incoming calls but not for outgoing calls.
Note that it's not possible to register the exact same FPL account simultaneously on more than one device or sip app (or ATA line). Only one registration per FPL account is allowed at any time. An ATA is one registration. A SIP app is another.
When there are multiple devices/softphones/lines using the same account, only the most recent registration is valid. The previous device will lose registration, and, consequently, incoming calls will not work on it. 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.
A more significant concern, though, is that multiple registration attempts can lead to temporary IP bans. The more devices being used with the exact same FPL account can make the temporary ban happen more quickly. Each time you reboot or restart your ATA or SIP app, it's attempting to register with Freephoneline again. Multiple registration attempts within a short period can result in temporary IP ban. Each time you reboot your ATA (or run a SIP app) it's attempting to register with FPL's proxy server again.
If you've been temporarily IP banned, you can try switching to another proxy server: voip,freephoneline.ca, voip2.freephoneline.ca, or voip4.freephoneline.ca:6060.
voip4.freephoneline.ca:6060 is used to help circumvent buggy SIP ALGs in routers, and it's a good choice to try if you weren't using it before.
9. Login to your ATA. Select the Status tab.
Navigate to status tab-->Port Status-->FXS port (being used for FPL)-->Registration
What is the registration status?
If step 8 is showing "connected" and step 9 indicates that your ATA is registered, then test again with an incoming call.
