[Asterisk-Users] Fine Tuning

[Peter Osborne]

Hello all,

We've been using our Asterisk system live for about a month now and I'm 
looking to tuning a few things. First, is echo, I receive a fair amount of 
echo during the first 10-15 seconds of incoming calls.

Next is a very weird problem. We have serveral Polycom IP300's and one 
Budgetone phone. It seems that if we unplug & move the Budgetone (which 
happens a fair amount as it is the phone we move to normally unreachable 
areas, some of the Polycoms will no longer work properly, the caller can hear 
us but we can't hear them. Very odd that the Budgetone triggers this but it 
is fairly consistent so we're close to just ditching the Budgetone.

Sound quality, when the volume is maxed on our Polycom phones, the sound is 
jittery and you can here what sounds like some sort of artifacts from 
compression or something like that, in some of the worst cases you can even 
hear random little beeps in the background.

Finally, all incoming calls seem to be a touch quite, basically the volume is 
always maxed on our Polycoms, is there a simple way to increase the incoming 
volume of all calls?

If anyone can help or point me in the right direction on these, it would be 
much appreciated. I have gone through the wiki and not found much on these 
issues.

Thanks,
Pete
