Yeah, sure. And there are some error messages mixed in too:

==============================

Before this was a series of REGISTER messages, and afterwards a series  
of OPTIONS messages. However, no errors there.

Also, this is without having set 'mailbox=1000' or 'mailbox=1000 at default' in
/etc/asterisk/sip.conf. And, now that I look at it again, the network  
mailbox settings for the Siemens phone won't have anything to do with  
these errors either, since it simply makes it possible to associate a  
button on each handset with an extension used to access a voicemail  
account.

Thanks,

Jaap
