[Linphone-users] prob with linphone 1.2.0

[li jiuying]

I installed linphone 1.2.0 stable.
when I execute linphonec I got this warning

Cannot open directory
/usr/local/lib/linphone/plugins/mediastreamer: No such
file or directory
Ready.
linphonec> Message:REGISTRATION_FAILURE

Message:cfg= sip:192.168.1.254, cfg->rid=1, rid=1
Registration on sip:192.168.1.254 sucessful.
Message:cfg= sip:192.168.1.254, cfg->rid=1, rid=1

but linphonec is registred on Asterisk. 
can that cause a prob of sound?
does sb have some ideas?
Thanks
Jo
