+This 'pbx' playbook adds `Asterisk <https://asterisk.org/>`_ and `FreePBX <https://freepbx.org/>`_ to Internet-in-a-Box (IIAB) for VoIP and SIP functionality e.g. for rural telephony.

+This initial release (for IIAB 6.7 in February 2019) supports Ubuntu 18.04 and Debian 9 "Stretch" — in future Raspberry Pi (Raspbian) might also be possible! (`#1467 <https://github.com/iiab/iiab/issues/1467>`_)

+Explanation
+-----------
 
 Asterisk is a software implementation of a private branch exchange (PBX).  In conjunction with suitable telephony hardware interfaces and network applications, Asterisk is used to establish and control telephone calls between telecommunication endpoints, such as customary telephone sets, destinations on the public switched telephone network (PSTN), and devices or services on Voice over Internet Protocol (VoIP) networks.  Its name comes from the asterisk (*) symbol for a signal used in dual-tone multi-frequency (DTMF) dialing.
