["徐颖" <xuying@xxxxxxxx>]

Hi everyone,
i get a compilation error about sipXexPhone
actualy it is a linking error
all codes are compiled successful
but I can not link them at the end.

In fact, it is the same problem in sipx-dev MAILING LIST 
(http://list.sipfoundry.org/archive/sipx-dev/msg02387.html
). I have just the completely same output.
Howerver, noboby gives a reply to it. 

Help please ! Now I could'nt find any clue..
