asterisk呼叫handle_response_invite: Received response: "Forbidden" 问题

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 '"å¼€å‘部 å°é™ˆ" <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。
