Two FAX machines connected to a ATA 186 can not send and recieve FAX to each other

Hi,

I have two FAX machines connect to one ATA 186, they can send and recieve outgoing  and incoming FAX from PSTN. However they can not send and recieve FAX to each other.

Hi Michael, i would suggest that you check on your CSSs and partions on the ATA module DNs .for you to place a call from one DN to another. the partition of the DN you are calling must be in the CSS of the calling DN. if you are not sure about this. place both in the none Css and none partition and test.

good luck.

rate if this helps !!

hi abukuru95,

Both has the same partition are on the same CSS and they can call each other. When I send FAX from either of the Fax machines to the other I just heared a fax tone then after awhile the call disconnects.

Hello,

Are they able to send fax to each other when not connected to the same ATA ? Was it working before ?

It sounds like a fax protocol error.

If you can, try with 2 ATA, sniff one ATA network port and look at the result : wireshark -> Voip Calls.
