[asterisk-users] Faxing success rate on PRI

[Marco Signorini]

Hi Gordon, thank you for your answer.

It's not mandatory to use an external box to handle the PRI. I was
thinking to use a Patton device instead of a TE120P just because I would
like to be able to switch to T38 in the near future or if working with
inband faxes will reveal problems.
I'm open to any suggestion, being in the initial requirements analysis
stage.

External devices, also, let me able to select a server independently by
the PCI, PCIXpress or any other connectors will be ready in the future,
maximizing the customer investment... but this could be the less
interesting part.

Thank you to All People answered me on this subject.
Analyzing your answers, seems that fax handling is still today
problematic with IAXModem and Hylafax... or I'm wrong?
What about other solutions?

Thank you and best regards,
Marco Signorini
