[Asterisk-Users] Data through T1, nethdlc

[Michael Welter]

I did everything you specified but couldn't get it to work on 2.4.25. 
With tcpdump I could see incoming ICMP, UDP, and TCP packets on each 
end, but they would just fall off the end of the earth--no replies at all.

The sethdlc and sethdlc-new programs are in the zaptel directory on CVS. 
  Depending on your kernel, one of them won't compile.

Somewhere I read that the "new" hdlc in 2.5.x was backported to 2.4.20 
or 2.4.21.  So I went back to 2.4.19 and hdlc works fine--I have four 
channels voice, 19 data, and the dchan on a T-1 crossover cable.

Contact me off list and I'll send the configs.
