Hello,
I have a problem after autoprovisioning.
In our office we're using DHCP autoprovisioning.
The phone user and SIP-ID is configured to the phone's MAC-address.
When I power on the phone it gets the configuration, but the user is still marked as unregistered. After I log in into the web dashboard and press the re-registration button the phone is registered to this user. When i try this directly through the key pad (the phone re-registration) it doesn't work.

Is there any Flag or Attribute that i must set that the telephone or the user is instantly registered?

For your Information : 
We're using SNOM D725 and Asterisk as software.

If you need more Information, feel free to ask.

Regards,
Benedikt
