Fax with IPO and grandstream ATA

[silicondarktide]

Hey all we have gotten a new IPO installed v9. with a new PRI line.
Everything is working fine calling in and out etc..
I tried using a fax with our new setup and it works ok over an analog port on a combo card. (running copper line all the way to fax)

We however want to use IP to setup lots of fax machines located in remote areas.

I cannot get it working over a grandstream ATA. If I hook up a analog phone to the line I can call out just fine...
Hook it back up to fax and it rings the other location and just hangs up after the fax starts going.

Anyone know any tricks for getting the grandstream ATAs to work faxing with IPO.

Well I think I figured it out myself. I got the faxes to go through ok send and receive.
Now I am getting a bunch of quality of service alerts in my system status every time I send or receive a fax.

It's the round trip (over 1000ms). From the SIP ATA to the PRI. Doesn't happen when just making a call using a butt phone.
