Ooma Forums

Just purchased the Telo yesterday from Best Buy. Hooked it up with no problems, after the 20 minute update download. I then proceeded to hook up my fax machine. I was able to send a 30 page fax with relative ease, but cannot receive a fax. The opposing fax machine calls in and my fax machine answers, but then after 2-3 seconds it disconnects.

I've enabled fax mode. Rebooted the Telo. The telo is after the modem, before the router. I can make and recieve phone calls with no problems.

Any thoughts would be appreciated. I guess my next step would be to call customer service?

i have never received a fax (though i have sent a number of them) so i am no expert here.

here is a doclink to some additional things to try like turning off error correction or lowering the transmission speed. http://www.ooma.com/support/knowledgeba ... er-devices.

something to start with and hopefully another Telo user with a fax will chime in with some more ideas.

Log into My Ooma and turn off the connection tone.

Thanks for the link. I looked over it and found useful information! But, I've done all of that and no change.

I did that too.

For what its worth my fax machine is a HP Officejet Pro 8500 Wireless. I could not find anything that said it was not compatible. I have been sending a fax to 1.888.473.2963. This is HP's fax back number. The fax goes out, and calls back in. The caller ID says "Unavailable Restricted". The fax machine says "Connecting...." then, fail.

Thanks for the replies!

i'm wondering if tinkering with your QoS settings on the router would be useful.

this would be kind of a hassle... but you might want to try hooking the Telo directly after your modem (so the router isn't in between) and see if you can receive a fax that way.

do you have a land line? i'm assuming you have been receiving faxes previously via the land line right? is this a new fax?

This doesn't solve your problem, but I can receive faxes from that number. Have you tried receiving a fax from anywhere else - for example FaxZero? Also, I have the Telo connected to my router, with QoS configured to give highest priority to traffic to/from the Telo.

I have the Telo between the router and modem now. Voice calls are excellent, no problems. I was using MagicJack, but could not stand the lack of reliability. Some of that may have been my PC, nonetheless I needed something better. The fax machine is maybe 3 months old.

I tried FaxZero, and the fax failed. The caller ID came up correct. I played with the QoS on the Telo (http://setup.ooma.com/) Maybe I have that wrong? I just reset it to default and will try again. I don't quite understand how the QoS is going to help. Maybe someone could explain?

Thank you!

here is a brief doc on QoS (the Call Quality form has a lot about this feature): http://www.ooma.com/support/knowledgeba ... ty-service. basically, the quality of service settings throttle how much bandwidth the device can use at a time. if you are not getting enough consistent bandwidth the fax could fail.

if your Telo is after the router though, it is the QoS settings on the router that will be most critical. have you configured any QoS settings on your router for the Telo? Often the routers have a similar QoS settings like the Telo.

For troubleshooting purposes, I disconnected my router and now I only have the Telo. No change. I have the QoS on the Telo setup for 0 (disabled) for both upload and download. I did some speed tests. Here are the results:

Download speed: 983528 bps
Upload speed: 370008 bps
Download quality of service: 89 %
Upload quality of service: 99 %
Download test type: socket
Upload test type: socket
Maximum TCP delay: 245 ms
Average download pause: 13 ms
Minimum round trip time to server: 84 ms
Average round trip time to server: 86 ms
Estimated download bandwidth: 983528bps
Route concurrency: 1.0
Download TCP forced idle: 0 %


I also hooked my MagicJack back up and sent a fax to the HP's FaxBack # and received a fax back, no problems.

Enable Fax Mode on My Ooma. Fax Mode is required for Telo to receive fax.
