Description:The change chan_sip.c on 4/26/04 going from cvs version 1.342 to version 1.343 with the comment "Use proper token for authenticating BYE" broke INVITE authentication.

In version 1.342 The Invite sent in response to a 407 message used p->peername to set the username= field.
(See function build_reply_digest)

In version 1.343 The Invite sent in response to a 407 message uses p->username if its set.
(See function build_reply_digest)

That seems all good except that in the sip_request function there is this code:

   if (ext)
       strncpy(p->username, ext, sizeof(p->username) - 1);

that overwrites username with the extension value.

As a result when the Invite is subsequently generated in response to a 407, the username= field in the authentication information is set to the number being called instead of the correct username value.

ASTERISK-1515 brought this to light and that patch was reverted as of latest cvs.  Please update your cvs tree.

If updating your cvs tree does not fix this issue, doublecheck your configuation, and post back here if it's still not working properly.
