[Asterisk-Users] Satellite Broadband and VOIP

[Mark Anthony C. Delfin]

Hi Sean,

We operate a VSAT network here in the Philippines (using  Shiron, FDMA 
Bandwidth on Demand) and offer VoIP using asterisk.  We do not sell our 
voip to our gilat clients since gilat has a higher latency (since it 
uses TDMA). Try to look for a satellite provider that has an average (to 
your country of voip destination) latency of below 600-800 ms and it 
must be consistent.

Also since, satellite has low upload bandwidth, try to have QoS behind 
the satellite modem and prioritize VoIP traffic
