Thanks Bjorn
I'm only using the softphone for "proof of concept" I will use a hard
phone once I get good results.
Once I get this link working I will add a wireless router and see how
far down the road I get with a laptop.
I will probably need some high gain antenna or a repeater.
Its funny , I go there to get away from all this technology but my
mother is quite old and I need to check
that she okay at least once a day.

You might want to try g729/g723, but as Dave pointed out bandwidth might
not be your main concern.
If you get more than 300ms latency in any direction I would look for
another solution.
In order to test the most critical point of failure, you need to set up
something at your cottage that would respond to ping, and ping it from
home. If you get stable ping reply below 300ms you should be fine.
You can also do a traceroute in both directions to find out where the
weak link is.
If that fails you can try a good QOS router to prioritize upload
traffic.
There's a whole bunch of Open-Source ones out there, unless you go with
a hardware-based one.
Smoothwall (http://smoothwall.org/) is one of them.
This is a good solution for anyone with low upload speed btw.
Chances are you might need to use gsm or ilbc, as most free soft-phones
doesn't come with g729/g723.
Some providers might not support gsm or ilbc though...

Subject: [on-asterisk] Satillite and SIP
Hi all, I am attempting to set up a SIP phone service to my cottage near
Bancroft this involves using a friends satellite internet connection and
some kind of wireless bridge.
We've just tried a SIP x-lite softphone which he installed on his PC.
The results are mixed.
He can hear me fine (presumably because his download speed is fast
enough) but his voice is broken up,
every two or three words get cut out making it very difficult to
understand.
Does any one out there know if we can use a narrow band codec or make
some adjustments to SIP to handle this problem.
This is the only viable solution as the cottage is 6 km from the nearest
phone line and is not within range of any cell tower (even with a 3 watt
analogue phone and yaggi antenna).
Hope someone can help.
Henry
