1. The SSMG + Open Source PBX (Asterisk™ , CallWeaver or FreeSwitch) solution is completely hidden from the user.  The Open Source PBX communicates with the Sangoma SMG via Woomera TCP socket.  The Sangoma SMG handles the actual TDM channels and ISUP messages.
   
   Asterisk™ Configuration:
   

   A chan_woomera driver is used to connect to the Sangoma SMG woomera server
   The chan_woomera has /etc/asterisk/woomera.conf file.
   
   Zaptel is NOT used: therefore there is no need for an /etc/zapte.conf file.
   Zapata is ALSO not used: no /etc/asterisk/zapata.conf file is required.
   However chan_woomera can work together with zaptel or any other asterisk channel driver.

   FreeSwitch Configuration:
   

   A chan_woomera driver is used to connect to the Sangoma SMG woomera server
   The chan_woomera has /etc/asterisk/woomera.conf file.
   
   

2. The USER configuration is done in extensions.conf file, where a Woomera OUTBOUND Context is used to handle outgoing calls, and a per trunk group INBOUND Context is used to handle inbound calls, for all physical channels handed by Sangoma SMG.
3. The Sangoma SMG supports Early Media, where the ring back is received from the far end telco.
4. The Sangoma SMG solution runs all over the world. There are a number of installations in United States, Italy, Pakistan, Paraguay, Philippines to name but a few.
