[asterisk-users] Digest Username/auth name mismatch‏

[t. k]

Hi 
 
I'm sorry.
I mailed the same question again. 
because, it cannot be yet solved.
any ideas with asterisk?

 
[Aug 20 14:40:12] WARNING[29315]: chan_sip.c:11806 check_auth: username mismatch, have <aaaa>, digest has aaaa at 192.168.0.1[Aug 20 14:40:12] NOTICE[29315]: chan_sip.c:20479 handle_request_register: Registration from 'aaaa <sip:aaaa at 192.168.0.1>' failed for '192.168.0.2' - Username/auth name mismatch 
 
[aaaa]
type=friend
username=aaaa
secret=xxxx
context=bbbb
canreinvite=no
host=dynamic
disallow=allallow=ulaw
 
The error seems that UAC set different username of digest. 
But UAC cannot send same username of digest and from for specification.
*Digest username set aaaa at 192.168.0.1
So I want to know how to solve with Asterisk.
