[asterisk-users] fax / t38 gateway

I'm trying to figure out how to handle our fax line when we switch to  
our asterisk for voice. After a lot of reading and poking about I have  
concluded, as have many others it would seem, that the best thing to  
do is either to have a separate pstn fax line or use some sort of  
internet faxing service rather than try and make faxing work in a way  
it's not meant to over voip lines.

The question I can't seem to find a good answer to is if there is a  
service/software that would allow a DID to be transferred to them and  
then they perform the t.38 gateway/conversion functions to which I can  
connect with asterisk as a t.38 endpoint and originator, or if there  
is a way that I could host that on my own server?

So essentially I am a bit confused that asterisk supports t.38 as an  
endpoint or originator, but there doesn't seem to be a way to convert  
to/from analog for interoperating with "normal" fax machines. I'm sure  
something exists or the code wouldn't have been written into  
asterisk... Can someone point me in the right direction?
