I have a following setup:

fax -> sipura 2002 -> asterisk -> sipura 3000 -> PSTN

Is there a way to setup some kind of passthrough so that the fax endures minimal amount of encoding? Other than normal "disable echo correction" and such?

I don't want to connect fax directly to 3000 because in the event of asterisk and/or power failure, I want my cordless phone, which is currently connected to 3000 to ring.

If anybody could give me some pointers, I'd appreciate it.

Perhaps a bit low tech, but... are you able to just use a splitter for the FXS on your SPA3000?
This makes:

PSTN-SPA3000--(SIP)---Asterisk--....
            --(line)------Cordless phone
                    ------Fax

Else, you could at least for outgoing faxes set the SPA2002's dialplan to dial the SPA3000 directly. Using codec 711(u) works best for fax purposes, or so I've heard.

This is how I had it setup before asterisk. I don't want to do it, because I want asterisk to perform fax detection before ringing the phone. Can't configure it this way with a splitter.

This definitely might be an option. Except I don't really know how to do it. And would it bypass encoding in this case? I don't think it would since it's still go over the network.

Maybe I can replace 2002 with another 3000, plug that through a splitter and try to configure it that way. Even then, I can only think of configuring for outgoing calls. I still don't think I can do it for incoming.
