Yes, I meant after porting has been completed.
I opened a ticket where you said and hope they will answer.
Responses are delayed due to the pandemic.
https://status.fongo.com/I'm uncertain whether it's worth trying to troubleshoot your issue if your SIP Username is in the process of being changed due to porting.
Have you received an email stating porting has been completed? Check your email spam folder.
Your original Freephoneline number will be replaced by the number you're porting into Freephoneline, and you will lose access to your original Freephoneline number.
If porting hasn’t been completed, there may not be much point in troubleshooting
Personally, I would stop reading here and hope for an eventual response to your ticket.

But if you do want to troubleshoot, answer the following questions, and follow the steps in order listed:
1) What brand and model modem are you using?
If you're using a modem/router combo, gateway, or hub issued by your ISP, contact your ISP to ask for assistance for disabling SIP ALG.
2) What brand and model router are you using?
a) Make sure whatever modem/router combo, gateway, or hub your ISP gave you is in bridge mode if you are using your own router. Call/contact your ISP if you have to.
b) Try disabling SIP ALG if you're using own router:

To understand why SIP ALG often causes horrible problems, please visit

3) What brand and model ATA are you using?
Your profile lists Grandstream for the brand.
I suggest following the settings listed in this guide as much as possible:
https://forum.fongo.com/viewtopic.php?f=15&t=18839 Obviously, only use the firmware for your own specific ATA model. Grandstream ATA firmware is located at
http://www.grandstream.com/support/firmware.
4) Use voip4.freephoneline.ca:6060 for Primary SIP server
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, 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, the FPL desktop application, 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 can make the temporary ban happen more quickly. Note that each time you reboot or restart your ATA or FPL desktop application, it's attempting to register with Freephoneline again. Multiple registration attempts within a short period can result in a temporary IP ban. Each time you reboot your ATA it's attempting to register with FPL's proxy server.
Do not test the ATA while the FPL desktop app is running and vice versa when using both with the same FPL account.
