[asterisk-users] 401 Unauthorized with Snom but not with Zoiper softphone

Thu Oct 7 06:54:58 CDT 2010

Hello,

I'm having difficulty with registering a SIP account in a Snom 320 
IP-phone. This is what sip debug tells me :

I would expect the Snom to try a second register, this time with some 
type of nonce. But there is just 1 REGISTER and 1 Unauthorized and 
that's it...

Other Snom phones with SIP-accounts go very well, but at this location 
the registration fails.

Another remark : when using a Zoiper softphone, the registration goes 
very well :

It's the same account, the same password, but other agent.

Can anyone help me with this please ?! I see no difference but there 
must be !!

Kind regards,
Jonas.
