strange in my implementation. I was using constant bit rate, when I set VAD as
enabled the Delay was bigger. You told me by IRC that VAD doesn't have to do
with the Delay, but it is happening to me. What<font face="Arial" size="2"> </font>could<font face="Arial" size="2"> it </font>be? </span><br style="color: rgb(0, 0, 0);"><br style="color: rgb(0, 0, 0);"><span style="color: rgb(0, 0, 0);">
4.-
Another thing you told me by IRC is to pack two frames in one packet to reduce
the bandwidth consumption. I was packing just one frame per packet and it
worked. I got audio in both clients but the bandwidth consumption wasn't as low
as I wanted. Actually my softphone is consuming 3.5 KBytes/sec (Speex+
RTPheader). So, I try to pack two frames per packet but the audio is too bad. I call the speex_encode_int method before call the speex_bits_write function.
What could be happening with this? </span><br style="color: rgb(0, 0, 0);"><br style="color: rgb(0, 0, 0);"><span style="color: rgb(0, 0, 0);">5.- Finally, I want to know if it's
possible to change the bandwidth consumption on the fly. I mean, If I use the
re-INVITE to change the parameters of a session<font face="Arial" size="2">, </font><font face="Arial" size="2">i</font>s<font face="Arial" size="2">
it</font> possible to change the parameters of the codec and then
change the bandwidth consumption too? </span><span style="color: rgb(0, 0, 0);" class="q"><br><br>I'm using QUALITY = 4 and

Speex in my softphone. Its features are really good, but I can't use all of them
