Re: [General] Bandwidth question
I have a similar situation in another East-European country.
Bandwidth is not a problem. I was using 256/256 kbps but 128/128 should work to if not used for anything else at the same time. So if your uncle gets an unlimited lower bandwidth he may be in a better situation.
The real problem is highly variable delay time and lost packets. If you have a bad and oversubscribed isp you may have this problem even on "fast" connections. That is the situation when people say "nothing but Skipe works"
FWD and Sipphone have no problem with any codec the 2 parties can support.(their "service numbers" still use G711 codec, and that's why you see "higher bandwidth" using that test numbers)
Codecs: G711 - best quality (80kbps)
G729 - best compromise quality/band (40kbps)
G723 - lowest bandwidth (23kbps)
ilbc - if you have a bad isp, this may be the only one to work acceptable (similar bw as G729)
ATA: if you can't do it without ilbc, try GRANDSTREAM otherwise go for Linksys/Sipura (most features) or Leadtek (easy to use)
