there is no such function in 1.7, but try to use an error_route in
your script to catch and remove bogus messages asap - see <br>

<div text="#000000" bgcolor="#ffffff"> <tt>Hello Pratik,<br>
<br>
In the very beginning of the script route use the
sipmsg_validate() function (see <a href="http://www.opensips.org/html/docs/modules/1.10.x/sipmsgops.html#id294004" target="_blank">http://www.opensips.org/html/docs/modules/1.10.x/sipmsgops.html#id294004</a>)
to check your message - you can do an exit there if the
message is not valid.<br>
<br>
