Those <br>should be analyzed as two problems (not one).<br><br>You will find plenty of posts in the archives relative to both. In <br>general terms, the choppy audio most
often is caused by shared IRQ's <br>when using a x100p or TDM400 card, and sometimes from a misconfigured <br>ethernet nic on the asterisk machine. For the nic card, ensure you are <br>running full duplex on the nic "and" whatever the nic is plugged in to.<br>Both need to be the same (half duplex will work in a low usage <br>environment, but full duplex is preferred.)<br><br>For the IRQ issue (and we are all assuming you are using a TDM04b card <br>since you really didn't say), do a 'cat /proc/interrupts' and make sure <br>your TDM card is on its own IRQ. If it is shared with other devices, it <br>is likely the cause for choppy audio. You'll see the TDM driver wctdm on <br>that list. If it is shared, then move the TDM card from one pci slot to <br>another to get it on its own IRQ.<br><br>The echo problem is going to be almost aways related to "too high" of <br>gains in zapata.conf. Your rxgain=10 and txgain=10 are way too high as <br>others have already noted. Try reducing those to
0 and restart asterisk.<br>Then increase the values (if needed) by increments of 2 until you find a <br>balance between low volume and echo. I'd suggest doing that "after" <br>resolving the IRQ/choppy audio issues.<br><br><br>> I have done this but I still get choppy sound and echo on some calls<br>> <br>> thanks<br>> <br>> */Giovanni Miano <giomiano @gmail.com="">/* wrote:<br>> <br>> Of course,<br>> Echo is 2 types: electric and ambiental.<br>> <br>> If u gain rx o tx more than you need, its return in recive and gen echo<br>> <br>> Try to decrase value, try to set 0 or .. in samecase -1 -2...<br>> <br>> 2006/3/13, sdgesa gaeharth <pollux1234567890 @yahoo.com=""><br>> <mailto:pollux1234567890 @yahoo.com="">>:<br>> <br>> Can you explain why?<br>> <br>> <br>> */Giovanni Miano <giomiano @gmail.com=""><br>> <mailto:giomiano @gmail.com="">>/* wrote:<br>> <br>>
