SPA-2000 series are having problems if you attach a fax device to them and try to send FoIP.
I have a system with a TDM card connected to local PSTN. Is it possible to receive FAX from a fax machine attached to a SPA-2000 and send it directly to PSTN?
SPA-2000 is configured to use G711 while faxing but there has not been even one single fax passing to PSTN.
Is there someone who knows how to get SPA-2000 or PAP to work with Asterisk faxing to PSTN?
Thank you in advance.
Use uLaw works best
Thank you for your post.
I am using G711 ulaw and still no go
