not sipgate. just tested with own phone landline call over sipgate to my ekiga.
codec handshaked was PCMA (G711a) and quality was fine.

the "robot" sound is very slight and inavoidable quantisation noise from sampling 
and compressing.

if its not slight then the sampling rate or width is too low or the soundcards ADC is bad 
quality.
