遇到一个SIP/2.0 407 Proxy Authentication Required.问题
[May 31 15:47:02] WARNING[17731]: chan_sip.c:19951 handle_response_invite: Received response: "Forbidden" from '"????‘é?¨ ?°é??" <sip:611@192.168.0.139>;tag=as6a9a35f7'
-- SIP/f201-0000000d is circuit-busy
== Everyone is busy/congested at this time (1:0/1/0)
抓包，看到SIP/2.0 407 Proxy Authentication Required.
解决：想到到在sip对接双方均有611帐号,而主叫方帐号不在线。所以用不同的账号呼叫解决此问题。
