[Asterisk-Users] Fax with Asterisk and Sipura 2100

[Darrell Long]

I know the subject of faxing has been covered in some detail, but I was 
wondering if anyone has a hardware configuration similar to ours that 
has faxes working successfully and would be willing to share any 
settings/insight.

We are unable to fax reliably with a Sipura 2100 connected to Asterisk. 
We do not route calls over the Internet and our network has very low 
latency. The Asterisk servers connect to Cisco Routers that have PRIs 
from various carriers. We have all the recommended settings in the 
Sipura ATA, with Echo Cancellation and Silence Suppression off, uLaw 
only for the codec, etc.

While I realize that no faxes going through passthrough like this will 
work 100% of the time, we currently have a less than 40% success rate 
with inbound faxes being the worst.

Any insight anyone has would be greatly appreciated!

Best Regards,
