I couldn't understand.
I used $ct.fields(expires).
if ($ct.fields(expires)) == '0')
xlog("L_ERR", "De-registration\n");
else
perform some operation
exit;
But its not working though.
I want to differentiate register and de-register SIP request. Thought
expires field in contact header would hold good. Is there any other way?
What is the mistake iam doing ?
