Hi,<br>
<br>
I am having issues sending and receiving fax on my asterisk setup.<br>
<br>
Currently I have a server that has 2 x E1 TDM cards one is sangoma and the other<br>
<br>
one is openvox. Both support echo cancellation.<br>
<br>
One of the e1 is connected to our telco provider via mfcr2 where all our<br>
incoming calls originate. On the other end is a pri connection going to HICOM<br>
PABX where the local attached to a fax is connected. Fax passing thru this<br>
connection are not getting thru and always getting drop.<br>
<br>
FYI: all of the 8xE1s are currently up with two using mfcr2 and the rest is ISDN<br>
