[Freeswitch-dev] Server having Freeswitch and two Sangoma cards and can't handle full capacity

[Sambit Jaysingh]

Machine is having
    CPU -  Intel(R) Xeon(R) CPU E5-2609 0 @ 2.40GHz(8 core)
    RAM - 32GB
    HDD - 600 GB primary and other attached storage is there
    OS - Centos 6
    Freeswitch version -  1.3.10b ()

After calls get connected, we play audio files and we have voice app flows
configured.
In the same machine only freeswitch is installed and JAVA application is
there which connects to freeswitch to make calls.

We are using ISDN calling on the machine. So how many max sessions can
freeswitch handle in practically?
The events from the ISDN network are processed very slower in the
freeswitch. Sometimes the main Java app waits for the required event for
any particular uuid, and gets other non required events from other uuids.
We are filtering that, but after sometime we have to forcefully terminate
that session because of non availability of event. This also leads to
non-usage of full capacity.
