Solved SBC connects to server but phones wont connect via SBC and aren't seen on PBX

[greychain]

I'm using a Yealink T19 E2 and T21 E2 and can not get the phones to be seen by the PBX. I have reinstalled the SBC V18 Debian, also tried the Windows version.

Where to check next?

Hi @greychain,

Have you done the following:

1. Restarted the phones after the SBC was installed and detected?
2. In the Management Console >> Security >> Anti-hacking, uncheck the box that enables SSL / TLS.
   
   
3. Login to the phone UI and paste the provisioning link manually into the Auto provisioning section.
4. In the phone UI disable trusted certificates.
5. Restart the phone.

Let me know if this works for you.

1. Done
2. Done, now phones can be seen on PBX
3. I am unable to access the file from a browser. I thought this was a way of testing that you can download it.
I have tried setting the provisioning link in phone and clicked on provision now - No result
4. Disabled trusted certificates. Phone rebooted and it works.

Thanks

It seems the T19s and T21s need a little hand here and there. Glad you've got it working now @greychain.
