I’ve got a working asterisk-1.2 + freepbx + sipura/linksys SPA-3120 receiving faxes 95% of the time. Other 5% aren’t receiving errors: just detection errors were NVFax detects voice and the call is transfered to main IVR. When I pick the phone, then I get fax tones. The line were SPA3120 is attached is a dedicated FAX line.
Is there a way to get an Inbound Route or an extension, to get faxing from ‘system’ without nvfax?
