[Asterisk-Users] budgetphone

[Bert Haverkamp]

Dear all,

I'm trying to get asterisk to register to budgetphone.nl. In several threads
 I saw people who got this to work:

But I've spent a whole saturday on it now and didn't get any further.
I also have a granstrema handytone 486. This thing manages to register.

I've tried to look into the differences between the sip messages with
ethereal. In ethereal I see the following sip conversation for the handytone:
192.168.0.60->81.23.228.150   SIP Request: REGISTER sip:budgetphone.nl
81.23.228.150->192.168.0.60  SIP Status: 401 Unauthorized    (0 bindings)
192.168.0.60->81.23.228.150  SIP Request: REGISTER sip:budgetphone.nl
81.23.228.150->192.168.0.60  SIP Status: 200 OK    (1 bindings)

In the first message the handytone tries to register, but it gets a request
for authentication (second packet) with a challenge. The third packet is a
retry to register, but this time with the response to the challenge. The
fourth packet is then the confirmation that all went well.

When I do the same with asterisk I get the following
192.168.0.35->81.23.228.150   SIP Request: REGISTER sip:budgetphone.nl
81.23.228.150->192.168.0.35  SIP Status: 401 Unauthorized    (0 bindings)
192.168.0.35->81.23.228.150  SIP Request: REGISTER sip:budgetphone.nl
192.168.0.35->81.23.228.150  SIP Request: REGISTER sip:budgetphone.nl
192.168.0.35->81.23.228.150  SIP Request: REGISTER sip:budgetphone.nl
...
Asterisk gives a response to the challenge, but never gets an answer back.
What is going wrong?
Hope someone can shed some light here..
