Freephoneline SIP Register Failed Suddenly

[quan_shi]

Hi,

I have been using freephoneline VoIP Unlock Key with my IP phone for years and suddenly the registration fails and never came back. What could be the possible reason? I checked on the website and did not see any notice for the service disconnection.

1) Check viewtopic.php?t=21012. Avoid using macro expansion variables or entering anything for proxy require headers. For Yealink, I think that field is called account.X.proxy_require. Basically, account.X.proxy_require should be empty/blank for Freephoneline to prevent the phone from sending a Proxy-Require header that can trigger the “Invalid proxy require header being sent” rejection message from Freephoneline's sanity check module.

You need to blank or clear the account.X.proxy_require field for the specific account you're using for Freephoneline (account.1, account.2, etc.)

Yealink config files are typically plain “key = value” lines (for example, account.1.label = Name), so you can search them as you can with any text file.​​
If you can export the config from the phone, open the .cfg and search for proxy_require (or account. then narrow it down).

I'm not overly familiar with Yealink IP Phones, but I took a look online, and it seems that Yealink deployments use a system/common config file (often named something similar to y0000000000<xx>.cfg) plus a device-specific file named <MACADDRESS>.cfg.​
If you control the provisioning source (TFTP/HTTP/HTTPS), search those templates/files for proxy_require and for any account sections (ex. account.1. / account.2.) that could set it.

2) Confirm your SIP server is set to voip4.freephoneline.ca:6060 (a DNS name) for example--and not a raw IP address--because Freephoneline’s server IPs can change over time. Also make sure you’re not using an unlisted or unsupported Freephoneline SIP server, because using servers not listed in their credentials documentation can lead to suspension: https://support.freephoneline.ca/hc/art ... redentials.

3) What brand and model IP Phone are you using?

4) What brand and model modem are you using?

5) What brand and model router are you using?

6) Do you see an error code? What's the full registration error message?

7) Login at https://www.freephoneline.ca/showSipSettings. Do you see anything indicating your account is suspended or banned (have you been paying the monthly 911 fee)?
