No, that's not significant.

'401 Unauthorized' is a perfectly valid response from Asterisk, because 
you have supplied a secret for that peer (203). What is supposed to 
happen is that the SIP UAC (Linphone) sees the 401 response (with a 
WWW-Authenticate header included) and retries the REGISTER with 
authorization info included.

However, here's something I hadn't noticed before: Asterisk is 
_receiving_ its own '100 Trying' response! What are the IP addresses of 
Asterisk and the softphone here? I suspect that .100 is the Asterisk 
server, in which case the Contact header of the REGISTER request from 
Linphone is completely wrong, since it should contain its own address.
