[Asterisk-Users] Echo cancel and fax

I have read that the digium t1 cards disable echo automatically if fax is 
detected, but I am assuming that this is hardware EC.

I have 2 TE110P cards that, I believe, do not have HW EC.
So, if I am using SW EC, does the EC still get cancelled on a fax call?
If not, is there a way to control this.

Current setup is PSTN---PRI---TE110P---Asterisk---TE110P---em_w 
T1---Panasonic DBS 576---Analog fax.

We were using a PRI between the Asterisk and Panasonic, but the Panasonic's 
PRI card died. This had CID, so technically I could use that info before.
But, now I am using a T1 card in the Panasonic, so I do not have CID and can 
not make outbound rules from that info.

A replacement PRI card is $1900 and because Asterisk is to replace the 
Panasonic, I do not want to invest in it.

Please advise.
