Hi All,
I am using Kamailio

​​

v4.4.x to load balanced traffic to FreeSWITCH servers. I have query regarding ds_ping_interval and ds_probing_threshold. We have very high traffic (around 200-400

​ (CPS)​

calls per sec) hitting on Kamailio which then distribute it to 2-3 FreeSWITCH servers.

​ ​

What is the optimal value should I set to ds_ping_interval and ds_probing_threshold?

If I set  

​​

ds_ping_interval=2 and

​​

ds_probing_threshold=1 then in every 2 sec, I would come to know if my

​​

FreeSWITCH server is down/up. But by setting such low values, I afraid there would

​be ​

lot of SIP traffic on network.

​ If I set high (say

​

ds_probing_threshold=5) then I may loose high number of calls (200 CPS, I will loose 1000 calls) in case 

​

FreeSWITCH server is down. ​

As I said earlier we have very high traffic hitting on Kamailio, can't kamailio use INVITE itself to probe FreeSWITCH server is down/up? In case of low traffic can't it switch over to OPTION mechanism?

​Thanks in Advance​
