Leave this at the default of 1200 and not 120
Please let me know if I have missed something.
Always check registration status in your ATA: in the Status tab-->Port Status, FXS 1 should be Registered.
FXS 2 should not be registered unless you have purchased two VoIP unlock keys.
Do not attempt to register both FXS ports with the exact same VoIP unlock key (or on another device). Doing so will lead to registration issues.
Also check "SIP status" after logging in at
https://www.freephoneline.ca/showSipSettingsPlease 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.
Where settings are similar, use this guide:
viewtopic.php?f=15&t=18839#p74000.
Register Expiration should be 60 minutes (this is 3600 seconds).
Use Random SIP Port: Yes
If rebooting the ATA always resolves the problem temporarily (provided Use Random SIP Port is set to Yes), then I would suspect a UDP timeout/NAT corruption issue developing in the device issued by your ISP, which is one reason why it's generally better to have your own good router for SIP services instead of relying on the device issued by your ISP. Refer to point D from
viewtopic.php?f=8&t=20199#p78976.
If rebooting does not help (and as long as you're positive your internet service is working and reliable), try changing Primary SIP Server to something else, such as voip2.freephoneline.ca.
Too many registration attempts within a short interval can lead to you being temporarily IP banned by the specific FPL server the ATA was sending registration requests to.
If you're temporarily IP banned, you could then try switching Primary SIP server to a different FPL server than the one you were previously using (voip.freephoneline.ca, voip2.freephoneline.ca, or voip4.freephoneline.ca:6060).
Registration timers are important.
SIP Registration Failure Retry Wait Time should be 120 seconds (not 20 seconds).
Register Expiration should be 60 minutes.
Otherwise intermittent outages are typically due to unreliable internet service.
A.Use winmtr
https://sourceforge.net/projects/winmtr/ if you have a Windows PC.
B. For Freephoneline.ca (based in Ontario), test to voip.freephoneline.ca (let winmtr ping about 200 times), voip2.freephoneline.ca, and voip4.freephoneline.ca. You can copy text to clipboard and paste your results (do not post your own IP public address though) and post them for others to examine if you want.
C. Look at the very last hop or line. Take a look at your average ping--and your maximum. You want those values to be relatively close.
You do not want high pings and lots of jitter (you do not want a lot of variation between each ping). If you get horrible results (pings over 200ms), you should probably avoid FPL.
I get between 11 (voip.freephoneline.ca and voip2.freephoneline.ca)-24ms (voip4.freephonline.ca) on average, depending on the server I'm testing to. Preferably, you want pings below 100ms.
Anything over 200ms is unacceptable.
What you don't want to see is 40, 45, 50, 35,
500, 40, 30, 45,
700. That's bad jitter, which leads to choppy calls or dropped calls.
And if you can't ping a server at all, something is definitely wrong. It's unlikely you will be able to register.
You want relatively consistent pings without a lot of variation. Severe packet loss and ping spikes can produce silence and dropped calls.
I also recommend reading page 42 under the choppy audio section from
download/file.php?id=2164 because what happens with severe ping spikes means your services and calls can drop.
