我正在Eclipse中开发sip客户端应用程序。我可以注册并生成呼叫。 使用INVITE请求生成呼叫。我正在使用linphone接听电话。但是当我接到电话时，没有声音。在Asterisk服务器中，我可以看到RTP数据包。当我通过linphone应答时，我从服务器获取以下信息：
v=0
o=root 1674073465 1674073465 IN IP4 xx.xx.xx.xx
s=Asterisk PBX 16.7.0
c=IN IP4 xx.xx.xx.xx
b=CT:384
t=0 0
m=audio 13472 RTP/AVP 0 8 101
a=rtpmap:0 PCMU/8000
a=rtpmap:8 PCMA/8000
a=rtpmap:101 telephone-event/8000
a=fmtp:101 0-16
a=maxptime:150
a=sendrecv
m=video 16180 RTP/AVP 34 103 100 108
a=rtpmap:34 H263/90000
a=rtpmap:103 h263-1998/90000
a=rtpmap:100 VP8/90000
a=rtcp-fb:* ccm fir
a=rtpmap:108 VP9/90000
