[Freeswitch-users] switch.conf.xml sessions-per-second issue

[Anthony Minessale]

All calls beyond the configured max sps will receive a 503.
For each 1 second period you can have up to 10 calls.  If you are sending
20 cps, 10 of them more or less depending on timing will receive 503 and at
least 10 will succeed.
There is no way to change it other than hacking code.
