Hi arnuld

2007/5/30, arnuld <geek arnuld gmail com>:

yannick, now i got it. my bandwidth is low, only 256 kbps which gives
the download rate of 29 kb/sec only.

You upload rate is allso important as you want to send your voice as well , I  guess your adsl is 256/128 kbits which is 32 kBytes/s  // 16 kBytes/s

So using G711 which is around 80 kbits/s ( everybody agree ? )  is a little too much for a 128 kbits/s line.

GSM = 8.0 kbps
SPEEX = 8.0 kbps

so you can even use the wideBand codecs Speex-WB : 20 kbits/s 

and it works fine now :-)

Great ! so I guess it would also work on 56k lines ....

(BTW, G.711 was unchecked by default)

It's true it would be better to put both speex WB and LB checked first then ILBC and GSM. if they are not available then ekiga would switch on G711 ? Am I right ?
