Re: [hylafax-users] Both T.38 and T.30 - How will Hylafax know which Asterisk connection to use

[Robert Moskowitz <rgm@xxxxxxxxxxxxxxx>]

Thanks for clearing this up for me.

We have been told to expect the next Trixbox 2.3 beta by the end of the 
week, and that will have many of the parts I need (probably could put it 
together now). So it is time to start trying to compile the T38modem code!

Read up on my notes from last year on how to and how to build an rpm....

I hoped that was the way of it.

I knew that.... Just not thinking through all the pieces. Well IAXmodem, 
it was nice knowing you! And Lee, thank you for all you are doing for us.

Now if we can be comfortable that the code will be maintained.

BTW, does T38modem make use of spandsp? How is it WRT GPL?
