[Asterisk-Users] sip phone configuration problem

[Ronald Wiplinger]

733 is a remote IP phone
608 is X-Lite on the internal LAN


I see a:
*CLI>... Registration from '"733" <sip:733 at voip.elmit.com>' failed for 
'218.x.x.x'

*CLI> sip show peers
733/733    (Unspecified )          D         255.255.255.255    0    Unknown
608/608    192.168.250.200    D         255.255.255.255   5060    OK (26 ms)

*CLI> sip show users
733      password                  test733      No   No
608      password                  default       No   No


I can call 608, but 608 cannot call back
733 cannot register


below is my sip.conf,     ...   Can anybody give me  a hint?
