使用jain sip创建sip代理应用。
客户端A->代理应用->客户端B
如果A呼叫B:A可以挂断,但是当B某时向Jain Sip发送BYE时,将481个呼叫分支返回给B。
当通话以秒为单位结束时,可以成功再见。
但是,如果通话在几分钟内结束,则当B发送BYE时,Jain会return回481个通话线路。
而且主叫客户A总是BYE成功。
已经检查了呼叫ID,请求uri,从到标签。还是不知道。
这是日志

getServerTransaction代码 自动对话关闭时。 st为null,但在getNewServerTransaction时仍然是异常。
public static ServerTransaction getServerTransaction(RequestEvent eventObject) {
ServerTransaction st = eventObject.getServerTransaction();
if (st != null) {
return st;
}
SipProvider sipProvider = (SipProvider) eventObject.getSource();
if (sipProvider == null) {
log.debug("getServerTransaction fail. SipProvider is null.");
return null;
}
try {
st = sipProvider.getNewServerTransaction(eventObject.getRequest());
} catch (SipException se) {
log.debug("getServerTransaction fail.", se);
}
return st;
}
答案 0 :(得分:0)
如果从jsip接收到481,则表明您在收到BYE时尝试查找一个对话框,该对话框可能目前不存在。如果jsip是代理,则不应有任何jsip对话框。
jsip中的代理应用程序不应依赖jsip对话框,而必须保持其自己的对话框状态(或者对于无状态代理而言,则不能如此)。代理应始终以无对话框状态模式实现,这基本上意味着避免创建任何对话框。您可以在这里https://github.com/usnistgov/jsip/blob/master/src/examples/forked/invite/Proxy.java
看到一个一般示例如果您已完成此操作,请发布一些代码并调试级别日志。
答案 1 :(得分:0)
您需要仔细查看路线,记录路线和 Contact 标头。
初始错误出现在User-Agent在代理服务器上收到的第一个 ACK 中。
ACK sip:14@192.168.100.45:5062 SIP/2.0
上述request-uri应该是200 Ok的联系人。
ACK sip:14@192.168.101.14:5014 SIP/2.0
我建议您修复所有联系人,记录路由,路由,然后确保您处理 ACK 和 BYE (在代理模式下):即,您需要使用 request-uri 和 Route 转发它们,而不是回答它们。
