Question

我正在尝试在Visual Studio 2012中创建一个小型VoIP客户端。我正在尝试通过UDP从PC向AsteriskNOW PBX发送REGISTER SIP消息。这些设备如下：

IP PBX AsteriskNOW: 192.168.1.37
PC that sends REGISTER message: 192.168.1.104
SIP account username: 117
SIP account password: abcd1234

所以，我试图发送的REGISTER消息如下：

REGISTER sip:192.168.1.37 SIP/2.0
Via: SIP/2.0/UDP 192.168.1.104:5060;branch=z9hG4bK213760691;rport
From: <sip:117@192.168.1.37>;tag=1270517038
To: <sip:117@192.168.1.37>
Call-ID: 1808066864-5060-1@BJC.BGI.B.D
CSeq: 2001 REGISTER
Contact: <sip:117@192.168.1.104:5060>;reg-id=1;
+sip.instance="<urn:uuid:00000000-0000-1000-8000-AABBCCDDEEFF>"
Max-Forwards: 70
User-Agent: Grandstream GXP1165 1.0.6.7
Supported: path
Expires: 3600
Allow: INVITE, ACK, OPTIONS, CANCEL, BYE, SUBSCRIBE, NOTIFY, INFO, REFER, 
UPDATE, MESSAGE
Content-Length: 0

当然，在

行

+sip.instance="<urn:uuid:00000000-0000-1000-8000-AABBCCDDEEFF>"

有PC，网络适配器MAC，而不是“AABBCCDDEEFF”。但是，当我尝试发送消息时，我从服务器得到以下响应：

SIP/2.0 401 Unauthorized

可能是什么问题？谢谢！
