I have a new install 4.0.1-1 all phones and trunks work good, only the fax does not receive or send, I have Virtual Fax license installed and 5 other license’s. everything is configured the same as I had on the V3 server. when calling in I hear fax tone but it fails, when sending out a pdf I get error.
An exception has occurred
Exception: mkdir(): Permission denied at file /usr/share/vitalpbx/www/includes/virtual\_faxes.php on line 0

Did you restore from a backup from VitalPBX3 on your VitalPBX 4? or this is a clean installation with no restored data?

clean install, hand configured no backup restore.
I changed ownership of folder, then I also ran vitalpbx --check-integrity which gave this result, rebooted system but fax does not still work.

Execute the command below to fix the issue:
```bash
chown www-data:www-data /var/lib/vitalpbx/fax

I changed chown as above but still not working, also now when trying to send out fax the caller ID name is missing so sip trunk provider blocks call, caller ID name was Ok before changes.

Are you still getting the permission error or this is a different error?

No error when sending, i think it fails because no caller id name, inbound fails as well.
Inside /var/lib/vitalpbx/fax I have this ?

You should share a call log using pastebin!

It’s like it can’t create the TIFF file in recvd, are these permissions correct. I don’t know what the “s” is

If this is an issue unique to my build I can create a new server and move licenses to it.

I have moved the fax license and routing back to Vitalpbx V3 until there is a fix for this issue, this issue could be a mistake on my part I’m just unsure but need this working for my customers.

We did some testing and realized that this is an issue of the Virtual Faxes add-on. We will fix it in the next update!

This morning the fax stopped working, no incomming or outgoing. Is there a way to check if the service is running, I tried systemctl status fax.service but thats not correct.
