Try having them save the image at the proper pixels and 72dpi.
I think there is an image size limitation on those of 256k as well so verify the image size.
If that image doesn’t work try to take the sample image, have them load that image in Photoshop lets say, then bring your logo image into that document and save it, try that one and see what happens.
I came across that no image works after a factory reset.
The phone makes the boot loop again.
I need to remove the background image, this does not resolve the boot loop.
After removing the image i need to make a factory reset again.
Then the phone boots up and works.
After the first boot i can add the background image and the phone boots up and works well.
If i do now a factory reset i get the boot loop!
If someone tries to recognize take care!
You cannot interact with the phone because it does not boot.
You have to wait for the right moment until the web gui comes up.
You have now about 10 Seconds to open this page to make a factory reset http://IPOFYOURPHONE/rsf.htm
Now i have no picture and there is a bootloop after reset.
I did not change anything except the line for the trusted root ca for letsencrypt.
The phone display says "Retrieving Configs https://ourpbx.com:1443"
This screen and then it reboots.
Language i have set is German.
Maybe its a error with the config files.
Its already really frustrating. It took me too much time to get this phones working. I work for at least w days on this issue. I will give it a last try else i will send all sangoma phones back.
Tested again, the boot loop stops instandly after i changed the background image url to a http site without user:password. I don’t needet to make a factory reset anymore. The boot loop stopped instandly after rebuilding configs
As Tony mentioned, go through support since you are using EPM and they will help and fix that going forward so you won’t have to manually edit the URL.
As stated either open a bug report at issues.freepbx.org or open a support ticket. But posting non stop about your issue here won’t get it resolved. The forums are not a bug tracker and no action takes placed based on a forum post.
