[asterisk-users] invite authentication error !?

[cnasterisk]

hi,
   Dear all.
   I setted a sip account on a sip trunk. when a  client call via this sip trunk, asterisk call failed on this trunk.
I have captured the sip messages on the host where asterisk located, and found that:

1. asterisk send a INVITE message to remote sip proxy without "proxy-authorization" field.
2. the remote sip proxy send back a " SIP/2.0 407 Proxy Authentication Required" message.
3. asterisk send a INVITE message with  "proxy-authorization" field.
4. remote proxy send back a "403(Forbidden)" message， that is mean "wrong password"

I also tested the sip account on a softphone, it works normal!

why this happed？ and how can i solve it?
