[Asterisk-Users] call center running Asterisk - sound quality- critical!

[Tamas]

Hi,

how do you record calls? Monitor app. or MixMonitor or something else?
How does your storage backend looks like?
What kind of channels do you use? Do you record IAX2 channels?
Regards,
 Tamas

I have done at least twice as many on my dual xeon 3.4Ghz system and had no problem as clients like to record every call that goes through the system. Then again, in my system, the in and out channels are mixed first before they are written to the disk.
