T19 E2 sip

[John Chuang]

I used Window X-lite to verify our Asterisk sip server.
It is no problem.

Then I use Yealink T19_E2(FW:53.82.0.20) to replace the Window X-lite,
but it always shows =>

chan_sip.c:17266 check_auth: username mismath, have <6002>, digest has <IP Phone>
chan_sip.c:28691 handle_request_regsietr: registration from'"6002" <sip:6002@912.268.11.27:5060>'
failed for '192.168.11.200:5060' - Username/auth name mismatch



"sip.conf for Asterisk"

What should I do ? Is it a bug ? Please advise !
