    Virtual Fax – T38 – Skyetel – PJSIP

    How do I make this work?

    I made sure Skyetel has T38 enabled.

    I set up a fax device – it says running and idle

    I set the settings in Global Fax Settings – plugged in my email, left the device port 3570, set the area code, left allowed hosts alone with 127.0.0.1 and localhost.

    I went to my inbound route and enabled fax detection and selected fax devices with the fax device I set up, detection time 5 seconds (also tried 2 and 10 seconds)

    If I send a fax through the system by attaching a pdf, I get an email back saying it failed.

    If I send a fax with a fax machine it simply says the number is out of order after it rings and makes a fax sound briefly.

    Found some settings in the PJSIP Trunk for enabling Fax Detection – they didn’t help though. 🙁

    In the advanced section of your fax extension you need to enable, Fax Enabled and Fax to Email

    For Outbound, you need to have your outbound route for your fax prepend 000038 to the number you are dialing, from the docs – https://support.skyetel.com/hc/en-us/articles/360040711554-T-38

    Attaching my outbound route, you can of course ommit the last rule as that is area code specific for 7 digit dialing.

    Can you provide a screenshot of the advanced section of the fax extension?

    This is what I have.

    Sorry I was looking at the setup on a v2 Vital system, I just configured inbound faxing on a v3 system, I didn’t touch Global Fax Setting just configured the Fax Device and enabled fax detection in the inbound route.

    Attaching the three screenshots
    Inbound Route
    Fax Device
    Fax in email

    Get some logs that we can check to help you better. Is your email properly set? Are you sending via SMTP or sending directly via postfix in the server?

    The guides never mentioned that the Fax ports are tied to the IAX ports.

    Yes, the Virtual Faxes add-on use the IAX protocol for the fax devices.
