我正在构建一个使用SIP over websockets并作为b2bua工作的java应用程序，即该应用程序在另一个SIP服务器上注册了许多sip用户。
我想知道是否有办法以某种方式重用现有的收听点？似乎对于每个SIP客户端，我应该创建SipStack，SipListeningPoint，SipProvider，然后调用SipProvider的{{1}}来实际发送SIP消息目标服务器。但是sendRequest的创建会分配一个新的套接字来接受传入的连接（我真的不需要），所以我需要为我在远程服务器上注册的每个SIP客户端打开一个套接字。
我尝试重用SipListeningPoint，但有一个限制，即每SipListeningPoint只允许一个收听点。我还尝试重用SipStack，但它导致了SipProvider中的例外。
SSLStateMachine（是的，我知道这个堆栈跟踪通常意味着SSL证书存在一些问题。但是当我为每个sip用户创建单独的监听点或者我只注册一个sip用户时，SSL连接成功建立）
以下是我设置的javax.net.ssl.SSLException: Received fatal alert: handshake_failure

属性：
SipStack我正在使用properties.setProperty("javax.sip.STACK_NAME", s"im.dlg.sip:$localAddress:$transport")
properties.setProperty("javax.sip.AUTOMATIC_DIALOG_SUPPORT", "on") // must be on to leverage dialog usage!
properties.setProperty("gov.nist.javax.sip.DELIVER_RETRANSMITTED_ACK_TO_LISTENER", "true")
properties.setProperty("gov.nist.javax.sip.REENTRANT_LISTENER", "false")
