[asterisk-users] Semi-OT Satellite?

[Darren Sessions]

I've used C-Band, Ku-Band, and DVB satellite internationally with VoIP  
for years at a previous employer and rarely had any problems was the  
sat link was up and running.

If you do plan on having 'remote offices', you'll want to make sure  
they all come back to a central earth station (hub and spoke topology)  
or you'll have virtually insurmountable latency issues (as Femi  
mentioned). Whatever you do though, don't stick the remote offices  
with their own internet bandwidth using VPN to connect to the home  
office for voice, data services as VPNs are extremely problematic over  
satellite.
