asterisk users - Mar 2004 - GSM Bandwidth - Test x Measures

Hi all!

    Everybody was talking about bandwidth consumption of the codecs but I have
one doubt about it.
    I prepared an Asterisk box with a TDM20B and a X100P (two FXS and one FXO).
Last week I traveled and carried my notebook so I could dial to a local ISP and
then connect to my asterisk box to make local calls.
    On the hotel, the quality of the phone line was terrible and the maxium
connection speed I made was 26.4k. Even with the bad connection I connected with
my asterisk box and then made a call and the quality was good. The client I used
was the IAX Phone that uses the GSM codec (as said at the web page).
    Any explanations? This is bothering me because I have to decide how many
clients a DSL (256/128) connection can support and if I take the measures I can
put a maximum of 3 (since its 35k with the GSM codec) and if I use my tests I
could use almost 5. What should I do? Help me. :-)

Thanks a lot in advance,

Joel Moraes
