there,</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=961192009-04102009>i found the problem
with the delayed audio between application and the nanoBTS. the reason was the
timestamp. a delay in openbsc causes packets to be delayed 1/2 seconds, so many
packet of 1/2 seconds arrived at nanoBTS after the delay at once,
nanoBTS buffers them.</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=961192009-04102009>the reason for the
delay was the "usleep(100000)" hack inside input/ipaccess.c. the patch will
use the tx_timer instead, so openbsc and application will not stall. this
timer was already used with BS11 messages. (there it uses 50 miliseconds instead
of 100 miliseconds.)</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=961192009-04102009>sending 10 messages
to nanoBTS will take almost one second. can we decrease the tx_timer value for
nanoBTS? how many packets can handle nanoBTS per second?</SPAN></FONT></DIV>
