[asterisk-users] Call recording format

[Vilius Adamkavicius]

Hi All,

We have a requirement to record over 60 simultaneous calls. Our recording
facilities are implemented using Monitor() over AMI. The thing we have
noticed that making 60 simultaneous call recordings using wav CPU load is
significantly higher (around 2 times more) than using gsm. Even writing call
recordings to /dev/null makes a big difference in CPU load.

What could be the reason for this? Is Asterisk updating wav headers every
time it writes?

What would be recommended hardware setup for over 60 simultaneous call
records?

Regards,
Vilius.
