channels/chan_dahdi.c 

*  Added doxygen comments to the major dahdi structures.
*  Fixed PRI and SS7 using an incorrect string value if the extension
delimiter is not present in the Dial() function.
*  Fixed SS7 not checking if the dialed extension is at least as long
as the stripmsd option.
*  Fixed PRI not handling unknown TON/NPI prefix letters correctly.
*  Fixed some uninitialized string variables on FXS ports.

configs/chan_dahdi.conf.sample
*  Updated some documentation.
