我需要使用Python套接字发送SIP消息，我已经使客户端向服务器发送了一些内容，但无法使客户端向服务器发送SIP消息邀请.

I need to send SIP message using Python sockets, I've made that client sends something to server but I'm not able to make that client sends a SIP message INVITE to server

#!/usr/bin/python import socket R_IP = '192.168.2.1' R_PORT = 5060 message = 'INVITE sip:user1110000000350@ SIP/2.0 To: <sip:user4110000000350@whatever>\x0d\x0aFrom: sip:user9990000000000@rider;tag=R400_BAD_REQUEST;taag=4488.1908442942.0\x0d\x0aP-Served-User: sip:user4110000000350@whatever\x0d\x0aCall-ID: 00000000-00001188-71C0873E-0@10.44.40.47\x0d\x0aCSeq: 1 INVITE\x0d\x0aContact: sip:user9990000000000@rider\x0d\x0aMax-Forwards: 70\x0d\x0aVia: SIP/2.0/TCP 10.44.40.47;branch=z9hG4bK1908442942.4488.0\x0d\x0aContent-Length: 10\x0d\x0a\x0d\x0aRandomText' def sendPacket(): proto = socket.getprotobyname('tcp') s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)#, proto) try: s.connect((R_IP , R_PORT)) s.sendall(message) except socket.error: pass finally: s.close() sendPacket()

你有什么主意吗?

推荐答案

好，我知道，也许会对某人有所帮助.

Ok I know, maybe it will help someone.

正确格式的SIP消息如下:

Proper format SIP message is as follows:

INVITE sip:user11@whatever SIP/2.0 To: <to> Call-ID: <call_id> <empty line> body

所以

message = 'INVITE sip:user1110000000350@whatever SIP/2.0\r\nTo: <sip:user4110000000350@whatever>\r\nFroma: sip:user9990000000000@rider;tag=R400_BAD_REQUEST;taag=4488.1908442942.0\r\nP-Served-User: sip:user4110000000350@whatever\r\nCall-ID: 00000000-00001188-71C0873E-0@10.44.40.47\r\nCSeq: 1 INVITE\r\nContact: sip:user9990000000000@rider\r\nMax-Forwards: 70\r\nVia: SIP/2.0/TCP 10.44.40.47;branch=z9hG4bK1908442942.4488.0\r\nContent-Length: 10\r\n\r\nRandomText'

\r\n非常重要，没有空格
