             Summary: Asterisk sends endless INVITE requests even call is ended
                 Key: ASTERISK-29059
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-29059
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: pjproject/pjsip
    Affects Versions: 17.5.1, 16.11.1, 14.7.8
         Environment: CentOS7
            Reporter: Ruslan Lazin


Lets say we have proxy that always return "SIP/2.0 407 Proxy Authentication Required" and "nonce" is different in each answer. 
Once we originate outgoing call to such server Asterisk falls to infinitive loop sending new INVITE after receiving 407 answer. It might be hundreds of thousands INVITE requests. Even when call is stopped ('core show channels' returns 0 active calls/channels) requests are still sending. Only Asterisk restart can stop INVITE sending.

To reproduce:
- Create a server that responses with "SIP/2.0 407 Proxy Authentication Required" and new nonce to every INVITE request. For test proposes you can use mine (sip.lazin.pp.ua:5060   - will be active till 31 Sep 2020) or use sipp (scenario attached) 
- Make an outbound call to anything at your_proxy
- stop call in any way (e.g 'channel request hangup all' in cli.)
- run ngrep and see that asterisk still sends thousands of INVITE
- restart asterisk to stop INVITE requests.
