[Asterisk-Users] Fwd: hdlc and kernel 2.4.26

[Michael A Rowley]

Hello,

I contacted Krzysztof Halasa, the maintainer of the current sethdlc 
code.  This is the response he gave me.

Of course, I have this working now.  Still some minor configuration to 
do, but It does work, and the connections to the internet are _much_ 
faster than when I went through the adtran...  I would highly recommend 
to anyone with a fractionated T1, with data and voice channels to set 
up HDLC and not mess with the T1 router cost and trouble...
