Kamailio作爲多個星號服務器的負載平衡器

Question

我有三臺運行Ubuntu 14.04的虛擬服務器。在一臺服務器上安裝了Kamailio和其他Asterisk。我希望Kamailio服務器作爲負載均衡器工作，並將傳入呼叫轉發到星號服務器（循環賽）。

我想先用一個星號服務器測試它，如果可以的話，我可以增加更多的性能。

我說我的SIP提供商的憑據是這樣的：

kamctl add test testpasswd 

然後，我添加星號服務器的調度表是這樣的：

INSERT INTO dispatcher (setid,destination,flags,priority,attrs,description) VALUES (1,"sip:10.1.1.3:5060",0,0,"","Asteriskl-I"); 

我改變了我的星號的sip.conf文件服務器，它連接到我的kamailio服務器，似乎工作。

我kamailio.cfg文件看起來像這樣：

如果我直接連接我的星號框，我的SIP提供它完美的作品。但是，如果我將它連接到kamailio服務器並將它連接到SIP提供程序的kamailio服務器，它不會。

我GOOGLE了幾個小時，嘗試了很多事情，我真的不知道我可以嘗試下......如果有人可以幫助我，我會非常高興！

非常感謝和問候

I added my SIP provider credentials like this:

kamctl add test testpasswd - 這是錯誤的。

檢查下面的鏈接瞭解詳細信息你應該如何建立對Kamailio SIP中繼，其使用用戶名/密碼認證：
