[Asterisk-Users] Sending credit card thorugh network/sipura 3000

[Chris Mason (Lists)]

I have a client we provided with 2 Sipura 3000 units for FXO on his two 
voice lines, he also has a fax machine connected to it's own line, and 
he has several Polycom phones on the network. This all works great. He 
has a shop in the building that is connected by a single network cable. 
In the sho he has another polycom phone, this works great, but he also 
has a credit card type machine for cellular Top Up as he sell this service.
In order to connect it I used a Sipura 2002 ATA and route it via the PBX 
to the Sipura 3000 FXO line. The call fails when it dials out normally. 
When I disable Echo Cancel on the FXO, it is able to make the call. 
However, this is a voice line so we can't permanantly disable the Echo 
cancel. I know you can cancel if when using the FXS port from an analog 
source, but I don't know how to do it on a SIP based call. Any idea how 
to make this work?
