+HandsFree Profile Audio Gateway diagram
+=======================================
+
+This diagram explains how oFono manages HFP AG.
+
+AT commands and unsolicited results are managed in their related atom (eg. ATA
+is managed in voicecall atom).
+The emulator atom is managing AT commands or unsolicited results that are not
+falling into a specific atom.
+
+1) HFP AG plugin registers a HFP AG server as soon as a voicecall atom exist.
+2) When a connection occurs on this server, HFP AG plugin creates and registers
+   an emulator atom.
+3) Emulator atom will start a GAtServer and registers non-atom-specific
+   AT commands to it.
+4) On emulator atom registration, voice call related atoms (voicecall, network
+   and sim) register AT callbacks they managed through emulator atom.
+
