- canreinvite=no*
- CPU busy 6.7% (93.3% idle) no transcoding
- CPU 30-35% with transcoding
- canreinvite=yes means that voice traffic goes from client to provider, directly bypassing the MOR system.
How can I increase the number of simultaneous calls?
Easiest way to increase the number of simultaneous calls is to connect an additional Asterisk server to your current MOR server.
Other implementations which can help you to increase the number of simultaneous calls can be found here.
