asterisk users - Dec 2005 - RE:how to solve error : cannot find extension context 'from-sip'

hi,
 
           I am a newbie to asterisk. I am tryining to connect two sip based
soft X-Lite phones to an asterisk server. i made following settings in sip.conf:
 
 [general]
 
 port=5060
 bindaddr=0.0.0.0
 allow=all
 context=bogon-calls
 
 [2000]
 
 type=friend
 username=2000
 secret=tejas
 host=dynamic
 context=from-sip
 
 [2001]
 
 type=friend
 username=2001
 secret=tejas
 host=dynamic
 context=from-sip
 
 and made following configuration in extension.conf :
 
 exten =>  2000,1,Dial(SIP/2000,20)
 exten =>  2001,1,Dial(SIP/2001,20)
 
 also i made proper settings in both SIP phones. Now the problem is when i am
making call from any of phone at srever i am getting an error : "cannot
find extension contex 'from-sip'.
 
  I analysed result in ethereal also. packets are comming to server. but server
is saying : "Proxy authentication required" . N ow i m not getting
where is the exact problem.
 can any one help me for this problem. Response to this problem is most welcome.
