My options include; 1) get a basic fax machine and plug it into a (iaxy/sipura?) ATA. Configure the ATA to do alaw so asterisk doesn't have to do any transcoding and hope it works. 2) use spandsp on my asterisk system and add suitable print queues 3) get an separate analog line and plug a fax into it 4) use a fax modem on the back of an existing system and an ATA (like 1 but even less hardware) 5) use a fax-to-email service
I've been reading about all the problems that people have with fax. What do folk recommend?
Get a separate analog line and plug a fax into it.
It's an unfortunate expenditure, but Asterisk just does not do fax very well. There seems to be some bug with it and receiving faxes.
Andrew's experience seems to indicate that you could mix numbers 1 & 2 with success. In other words, send with #1, and receive with #2. I don't have any experience with #2. My experience with #1 is that sending works fine, but receiving is not fine.
We have a PRI and I run both incoming and outgoing faxes through a TDM400P. It works without problems. No need to mess with codecs/compression at all. The signal that comes in on the PRI is the same one that goes out to the fax machine and vice versa. The fax machine is a big ricoh multifunction unit.
