24 hours still you've reached for the limit of simultaneous

Postby chimq333 » 01/21/2022

Recently, I've got a lot of the "you've reached for the limit of simultaneous calls". Normally it will resolve itself in 12 hours. But this time, it's been 24 hours and still the same message. I wonder if there is anything I can do to resolve this issue? And what should I do going forward to avoid this issue? Thanks in advance.

FPL supports 2 channels. There can be a maximum of two active calls per FPL account.
Each call can last a maximum of 3 hours.
If two calls haven't disconnected because BYE hasn't been received or processed properly somewhere along the path, then you wouldn't be able to make more calls.
Also, if someone else or another device is using your FPL account, then that could also cause problems.


Go through this list, please, step by step, and provide requested information:

1. What is the brand and model of the modem provided by or used with your ISP?

a) If you're using a modem/router combo, gateway, or hub issued by your ISP (and are NOT using your own additional separate router), contact your ISP to ask for assistance for disabling SIP ALG in the modem/router combo, gateway, or hub. Disable SIP ALG.


Here are two examples for disabling SIP ALG in gateways:


i) Hitron CGN3ACSMR and CODA-4582 series gateway modem/router combo from Rogers (and possibly other ISPs)


Open your web browser, and login at 192.168.0.1. Default username is cusadmin.
Select the “Basic” tab and disable “SIP ALG.” Click the “save changes” button.


ii) Arris XB6 from Rogers

Open your web browser, and login at 192.168. 0.1
Navigate to Advanced-->Options.
Uncheck the SIP box.
Click "Apply".


2. What is the brand and model of your router? If you are also using your own separate router in addition to the one supplied by your ISP, then you should be enabling bridge mode instead in the modem/router combo, gateway, or hub issued by your ISP.

For Bell Hubs, visit http://forums.redflagdeals.com/please-s ... r-1993629/. For Bell and Virgin Hubs, I find it's often simpler to perform PPPoE login in your own router (this is PPPoE Passthrough) and disable Wi-Fi in the hub. You will need the PPPoE Username and Password from Bell or Virgin.

For Rogers, visit https://www.rogers.com/customer/support ... ridgemodem.
Shaw users will have to call Shaw to enable bridge mode at the time of this post.

For Telus Wi-Fi Hubs, put LAN port 1 on the Hub in bridge mode. Then connect your router to LAN port 1.
Alternatively, contact Telus and ask them how to enable bridge mode.


3. Disable SIP ALG in your own separate router if you own one. Here is an example: https://www.obitalk.com/info/faq/sip-alg/disable-alg.
In Asus routers, SIP ALG is called SIP Passthrough. In Asuswrt-Merlin, the ALG is "+NAT Helper". Just make sure SIP Passthrough in Merlin does not show "+NAT Helper".

4. Don't use DMZ and don't port forward in your router. Both are security risks. Only port forward if you have no other choice.

5. Are you using any other SIP devices (smartphone app, FPL desktop app) other than your Linksys PAP2?

6. Are you sharing your FPL account with anyone?

7. Which proxy server is your ATA registered with? voip.freephoneline.ca, voip2.freephoneline.ca, or voip4.freephoneline.ca:6060?

8. Log into your ATA (switch to "advanced view")


Under Voice-->User 1 and User 2 (both of these)
Check Call Forward Settings


a) Cfwd All Dest:

That field should be blank. If there's a phone number there you don't recognize, you were hacked.
Make that field blank.

b) Cfwd Busy Dest

That field should be blank. If there's a phone number there you don't recognize, you were hacked.
Make that field blank.


c) Cfwd No Ans Dest

That field should be blank. If there's a phone number there you don't recognize, you were hacked.
Make that field blank.

9. Navigate to "Info"-->Line 1 status and Line 2 status in your ATA

Check call 1 and call 2 state

What is their state?

10. When you check your call logs, are you seeing calls that you don't recognize?
If so, someone else is using your FPL account.

Login at https://www.freephoneline.ca/doGetCallLogs.
Select current month, and click the submit button.


11. Login at https://www.freephoneline.ca/showSipSettings

SIP Status should show connected

If you don't recognize the device listed for SIP User Agent, you've been hacked. In that case, someone else would be using your Freephoneline account.

12. While you're troubleshooting this problem, keep "Follow Me" disabled. Login at https://www.freephoneline.ca/followMeSettings.


By the way, when there are multiple devices/softphones/lines using the same FPL 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 FPL desktop app) or with another device. Registration is required for incoming calls. It is not required for outgoing calls. Only one registration per FPL account is allowed at any time. A single line on an ATA is one registration. A SIP app is another. 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 a SIP app, it's attempting to register with Freephoneline again. Multiple registration attempts within a short period can result in temporary IP ban with the proxy server being used.

Thanks so much for your reply, much appreciated! SIP ALG was always disable. My call log doesn't have any numbers that I don't recognize. But "Cfwd All Dest:" has an IP address in it. Does that mean I was hacked at some point?

Possibly.

1. Delete that entry.

2. Login (admin and advanced view) to your ATA.
Navigate to Voice-->System-->admin password

Change it (make sure you won't forget it). Don't use default device passwords for anything connected to the internet.

3. Also, navigate to Line 1 (or whatever line is being used for FPL)-->SIP settings, change SIP Port to a random number between 30000 and 60000.
Submit settings. Reboot ATA. That may help to avoid port scanners/hackers.

4. Navigate to Voice-->Line (being used for FPL)-->Proxy and Registration-->Proxy
What's listed there?

Please go through the previous steps as well and provide the info requested. Thanks.

As far as I know, you shouldn't be getting that error message unless there's current, active calls using your FPL account.

Thanks again! I've done all the steps. And the proxy is 208.65.240.44 & 208.64.240.44. Do I need to change it?

That's voip.freephoneline.ca for now. Why are you using IP addresses?

& 208.64.240.44. Do I need to change it?


1. That IP address is no longer used for FPL.

It's better not to use IP addresses, unless you're experiencing a DNS problem.
viewtopic.php?f=15&t=19702

2. I'm not sure what you mean by "and" here. Do you have two FPL VoIP unlock keys?
You can't register both Lines on the ATA using the same FPL account. You will run into problems.
You need to own two VoIP unlock keys if you want to register both lines on the ATA.

1. those two IP addresses have been there for a very long time. I remember at one point there were some issues and that's why I changed to IP address
2. One is for Proxy and the other one is for Outbound Proxy. Should I keep them the same? or leave the "Outbound Proxy" blank?
3. Here are some of the setting that I have now... could you take a look and let me know if I need to change anything?

Proxy: voip.freephoneline.ca
Outbound Proxy: voip2.freephoneline.ca
Register: yes
Register Expires: 180
Use DNS SRV: no
Proxy Fallback Intvl: 3600
Voice Mail Server: "is blank"

Use Outbound Proxy: no
Use OB Proxy In Dialog: yes
Make Call Without Reg: no
Ans Call Without Reg: no
DNS SRV Auto Prefix: no
Proxy Redundancy Method: Normal



Thanks!

Avoid using IP addresses unless you're experiencing a DNS issue.

Outbound proxy should be blank


Outbound Proxy: voip2.freephoneline.ca


delete

Register Expires: 180


That should be 3600 seconds.You are likely being temporarily IP banned by the proxy server your ATA is attempting to register with.

Frankly, your configuration is a mess. I would perform a factory reset on your ATA (provided your ATA was never locked to another service provider) and use this guide:
viewtopic.php?f=15&t=16294
Pay attention to the 3 steps listed in the first post.

I have made all the changes, thanks again!! Unfortunately, my ATA is very old and was locked when I got it so I can't factory reset.

Be sure to go through the PDF guide listed in the first post (keep in mind that GMT-5 is for EST/eastern time zone) at viewtopic.php?f=15&t=16294, and also do the three steps listed in the first post.
Save changes. Then reboot router. Wait for it to be fully up and running. Then power cycle or reboot ATA.

Afterwards, test to see whether incoming and outgoing calls work.
