Hello,
I've a jtapi app and I've two AES servers.

What's is the recommended way to connect to those AES servers, should I simply specify their addresses in TSAPI.PRO file or via the System.setProperty("com.avaya.jtapi.tsapi.servers", "ipserver1:450,ipserver2:450") and then the jtapi library will handle failover automatically in case one of the servers is down.

Or should I connect to server1 only and in case of failure connect to server2.

Thank you,

That is somewhat a matter of choice. The automated failover is convenient but it may not be what you want for your application in terms of control over operations. There is also a question of are the two AESs identical, or is there a potential difference in loading, network topology that makes one better than the other when all else is equal.

Thank you,
Indeed the two AES are identical.
I prefer to control from app where I just need to restart listeners in case of provider shutdown.
