FYI,<br>
<br>
Customer was trying transmit FAXes over ATA which AudioMode was still
0x00350035 instead 0x00150015.<br>
Now it's OK!<br>
<br>
I just don't understand why FAX over PSTN works whit both AudioMode and
FAX over WAN don't...<br>

have a problem with fax transmissions over WAN.
<br>
<br>
In the following situation, it doesn't work.
<br>
<br>
ATA186(1) ---- Router --- IP WAN --- Router --- ATA186(2)
<br>
<br>
Call is established, users can talk each other, but when fax
transmission starts, it fails.
<br>
Both ATAs are using a Region which places calls in G711 codec between
them.
<br>
<br>
If I transmit fax over PSTN, at the same FAX machines and ATAs, it
works fine.
<br>
PSTN --- Router --- ATA186
<br>
<br>
I've followed this guide to configure passthroug mode.

<br>
<br>
Am I missing anything or FAX transmissions in ATA-to-ATA scenario
doesn't work?
<br>
<br>
CallManager 5.1.3
<br>
ATA SCCP 3.02.03(051201A)

Thanks
