Hi I've got a TE121 PRI card which is giving me endless problems with HDLC errors. I believe from reading various posts that dahdi 2.1 doesn't give the same errors that 2.2 gives. I've got the lastest Elastix 1.5 installed and updated and would like to recompile dahdi 2.1 from the source rpm. How do I go about doing this? I've downloaded and install the src rpm and installed the supplied patches, do I just do a ./configure & make & make install? How will it affect the dahdi 2.2 rpm that's installed? Will I have to recompile Asterisk as well? Any help would be greatly appreciated.
