We use IAXModem-1.2.0 built from source and packaged as an rpm using
mock/rpmbuild together with Hylafax+-5.5.3 from epel.  Since April 2013 this
combination has been running two dedicated POTS lines through a TDM800-p8 on
our Atom CentOS-6.3 based Asterisk-11.7.0 (current version) box without any
reported difficulties (once I sorted out the upstart stanzas).

As this is the only combination I have experience with it is the only one I
can recommend.  But it has proven very reliable so far as I am aware and I
would be made aware pretty quickly if it was not.
