Can't Hangup correctly "Failed to authenticate on BYE"

Asterisk Asterisk Support

Hi,

I’ve got an issue on asterisk 1.6 (Debian squeeze)
I can’t hangup with certain trunk sip provider.
extension.conf :

exten => s,1,Answer()
exten => s,n,NoOP('test')
exten => s,n,Hangup()

Asterisk on debug :

[Sep 7 10:20:52] NOTICE[17598]: chan_sip.c:18858 handle_response: Failed to authenticate on BYE to '<sip:XXX ....

as you can see, there’s no Authorization: Digest on the BYE, so provider return a 401
Same with asterisk 1.8 (ubuntu 12.04)

Why asterisk doesn’t send this header on the BYE ?

You need the 401 response to know the nonce and digest method.

However, it is not normal to re-authenticate on in dialogue requests. I would wonder if the remote system had some problem in matching the request with the existing session.

Thanks for your answer :smile:

I agree, but asterisk doesn’t answer to this 401 (it has the digest so it can answer). Is there a way to force the “re-authentication” ?

Maybe, thanks for the hint.

I having the same issue. I am using a Vonage Softphone. It successfully answers the call and executes a Playback() and Verbose() command but it fails on Hangup().

“Failed to authenticate on BYE to …”

I am running a Ubuntu Server on VirtualBox with Windows 7 Host. Asterisk version is 1.11. I can provide my sip.conf if that helps.

Any suggestions or workarounds?
