Servlets Must Be Non-Blocking
4.7 send Calls Are Buffered
If your SIP Servlet calls the send method within a SIP request method such as doInvite, doAck, doNotify, and so forth, keep in mind that the WebLogic Server container buffers all send calls and transmits them in order after the SIP method returns. Applications cannot rely on send calls to be transmitted immediately as they are called. Caution: Applications must not wait or sleep after a call to send because the request or response is not transmitted until control returns to the SIP Servlet container.Parts
