<DIV><FONT color=#000000 size=3 face=宋体>Hi ：</FONT></DIV>
<DIV>The version of opensips that I used is 1.6.2.</DIV>
<DIV>And in the cookbook of 1.6.2 I get the description below:</DIV>
<DIV>if (is_method("INVITE"))
<DIV> { </DIV>
<DIV> $var(aline) = $(rb{sdp.line,a,1}); </DIV>
<DIV> xlog("The second a line in the SDP body is $var(aline)\n"); </DIV>
<DIV> } </DIV>
<DIV>So, I think the version of 1.6.2 is support the sdp transformation.</DIV>
<DIV>I want to know how to use the sdp transformation.Why I get the error,and
how to avoid the error.</DIV>
<DIV>Thanks & Regard</DIV>
