------------------------------------------

This is an example of un-register attempt after successful registration is already active and AOR is saved by Asterisk:

> Hi,
> We have an Asterisk server that has PJSIP configured in UDP transport mode. As this is a test server - only one SIP endpoint created with AOR and AUTH sections. Authentication mode is set to "auth_username,username,ip,anonymous". I can register to the PBX fine with my softphone, but upon each request Asterisk for some reason asks for credentials, even for de-registration, which is important to me. According to Asterisk documentation:
> https://wiki.asterisk.org/wiki/display/AST/Tests+for+Registration+Functionality
> section 'Un-registration tests' it shouldn't be asking for credentials as user is already registered in system. Same applies to calls, after successful registration when softphone sends INVITE packet Asterisk first replies with 401 Unauthorized and after authentication processes the call ok. What could be an issue of such behaviour? Thanks!
