If you go higher than this you start getting to much latency, if you go lower than this you start using to much CPU.<br> <br>400 byte is 50ms, meaning we have spent a lot of the latency budget already here, but this shoud be run-time configurable per channel as per need.<br> <br>- G.711 6 ms<br>- IVR is 250 ms<br>- 729 10 ms<br>- 723 30 ms<br> <br>etc.<br> <br>You need to take into consideration that you are on a system with 8, 16 or 32 E1's of whick some is running IVR, others SIP, others swicthing back out on a different E1 etc.<br> <br>Jan<br> </span></blockquote></div><br></div></body></html>
