问题描述
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@.com SIP/2.0 To: <sip:user4110000000350@whatever.com>\x0d\x0aFrom: sip:user9990000000000@rider.com;tag=R400_BAD_REQUEST;taag=4488.1908442942.0\x0d\x0aP-Served-User: sip:user4110000000350@whatever.com\x0d\x0aCall-ID: 00000000-00001188-71C0873E-0@10.44.40.47\x0d\x0aCSeq: 1 INVITE\x0d\x0aContact: sip:user9990000000000@rider.com\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.com SIP/2.0\r\nTo: <sip:user4110000000350@whatever.com>\r\nFroma: sip:user9990000000000@rider.com;tag=R400_BAD_REQUEST;taag=4488.1908442942.0\r\nP-Served-User: sip:user4110000000350@whatever.com\r\nCall-ID: 00000000-00001188-71C0873E-0@10.44.40.47\r\nCSeq: 1 INVITE\r\nContact: sip:user9990000000000@rider.com\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
