[Asterisk-Users] Fax over 2 bridged TE110P channels

Tue Apr 4 11:34:17 MST 2006

I suspect that in your case the fax channels are not natively bridged. I'm 
not sure whether native bridging will work if you are using 2 cards.  It 
should work if the ports are on one card i.e. TE205P or TE210P in which 
case there will be no intervention of Asterisk at all.

You might want to check with Digium support to verify

Let me know the result.

Cheers!
