[Asterisk-Users] 128 kbs satelite link

[Patrick Cantwell]

At one point I was tasked with investigating some sort of data link between
New York City and Cebu, Philippines.  We were interested in doing voice over
this link, and quickly learned that voice over satellite links is *not* very
usable.  We ended up with an international fractional T1 (and I was laid off
before the project was completed, so I can't tell you how it worked out!).

i havent tried a satellite link with * yet, but i do have it running on a
128k wifi link.  due to the technology used for the wireless link
(turbocell) the smaller packets are grouped together into a "superpacket"
- this means the lower bandwidth codecs dont work very well.  i found that
using a higher quality codec actually gave better results.  so i use ulaw
all the time now - resulting in well, one concurrent call.

so this really has nothing to do with answering your question, but maybe
it might help someone else.
