While this thread is already in the archives, I'll throw my opinion on the table, too.
The latency is about .25 seconds to and .25 seconds from the satellite. There is additional propagation delay in the system. Also, TCP/IP relies on propagation delay to optimize traffic, but doesn't handle delays this long well. There is special purpose hardware available the sends the traffic to an from the satellite with a different protocol. This helps the satellite calls quite a bit. http://www.mentat.com/skyx/skyx-whitepaper.html John Todd reamed me out the last time I suggested that you need this hardware, he says he has voice working fine over a satellite link. And he knows what he's talking about. I thought I would save him some time, this time, by putting this in. ;-) There is, of course, also the problem of the upload speed. The consumer grade satellites don't offer much upstream bandwidth. You can get better upload speed from some of the commercial satellite carriers. http://www.tachyon.net/ Paul Paul Mahler mail:[EMAIL PROTECTED] phone: 650.207.9855 fax: 877.408.0105 -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bisker, Scott (7805) Sent: Wednesday, December 17, 2003 7:06 AM To: [EMAIL PROTECTED] Subject: RE: [Asterisk-Users] 128 kbs satelite link Similar to online gaming, I would think that the propagation delay with the satelite connection would make calls unbearable.

In particular I am interested to hear how many calls could be put through 128Kbs satelite link simultaneously?
