* depends on libmp4v2 <http://code.google.com/p/mp4v2/>
(originally compiled against v1.6.1)

* File format details:
	- Files must be hinted (mpeg4ip can be used to create the hint
	  tracks).
	- Video track encoding must be supported by FS (e.g. H.263)
	- Audio track encoding must be PCMU/8000/Mono. The audio track
	  can be created with this tool:
	<https://asteriskvideo.svn.sourceforge.net/svnroot/asteriskvideo/tools/pcm2mp4.cpp>

         as that does not work on gcc (Debian 4.3.2-1.1) 4.3.2
         and probably other compilers when the inlined function
         is not defined in the same compilation unit

Requires libpri-1.4.12_beta1 or newer!
Completely untested, AOC-S/D/E ChargingRequest operations are sent to NT (DTAG BRI PTMP),
but rejected with "Unrecognized Operation".

NOTE: FreeTDM core needs support for this to be useful!
      Only AOC-E events are decoded and sent to the log.

To enable:
    Set (or add) <param name="opts" value="aoc"> in your
    libpri_spans span config.

ftmod_libpri: Write fatal error message during span configuration to console (and to span error log).

"all" and "none" can only be used alone,
other flags are additive.

freetdm: convert ftmod_libpri (+ libpri_spans) to use new ftdm_configure_span_signaling() interface.

This fixes several issues with parameter handling (e.g. default alaw/ulaw selection being totally useless).
