Neels Hofmeyr ecacdc65c3 build: be robust against install-sh files above the root dir 
Explicitly set AC_CONFIG_AUX_DIR.

To reproduce the error avoided by this patch:

  rm install-sh        # in case it was already generated.
  touch ../install-sh  # yes, outside this source tree
  autoreconf -fi

This will produce an error like

  ...
  configure.ac:16: error: required file '../ltmain.sh' not found
  configure.ac:5: installing '../missing'
  src/Makefile.am: installing '../depcomp'
  autoreconf: automake failed with exit status: 1

See also automake (vim `which automake`) and look for 'sub locate_aux_dir'.

Osmo SIP Connector
==================

Simple utility to map MNCC to SIP and SIP to MNCC. The VTY interface
can be used to make configurations. The code doesn't have any RTP or
transcoding support.

Call identities can be either the MSISDN or the IMSI of the subscriber.


Requirements of Equipment
^^^^^^^^^^^^^^^^^^^^^^^^^

* DTMF need to be sent using SIP INFO messages. DTMF in RTP is not
supported.

* BTS+PBX and SIP connector+PBX  must be in the same network (UDP must be
able to flow directly between these elements)

* No handover support.

* IP based BTS (e.g. Sysmocom sysmoBTS but no Siemens BS11)

* No emergency calls

Limitations
^^^^^^^^^^^

* PT of RTP needs to match the one used by the BTS. E.g. AMR needs to use
the same PT as the BTS. This is because rtp_payload2 is not yet supported
by the osmo-bts software.

* AMR SDP file doesn't include the mode-set params and allowed codec modes.
This needs to be configured in some way.
