Fax Client Invalid Caller ID

[Daniel_D]

Hi Guys
im testing setting up the fax service
I have inbound/outbound through email working using mailgun
but when i try and send through the fax page, it doesn't work

looking in the logs i get the error 2026-02-06 01:26:58] production.ALERT: Invalid Caller ID is set up for fax server 50000: XXXXXXXX

ive looked around where i can try and fix the caller id, but haven't had any luck
any suggestions?

This error message seems to actually belong to the email-to-fax code. The caller ID is set in the Fax Server settings. Is your caller ID selected, and is it a US-based number?
