<tt>Hi,<br>
<br>
Ideally you should init the vars before their usage, rather than
trying to reset afterwards. It is much safer.<br>

<div>I think this feature will have existed in both 1.6 and 1.11
(see <a moz-do-not-send="true"
href="https://www.opensips.org/Documentation/Script-CoreVar-1-6#toc1">https://www.opensips.org/Documentation/Script-CoreVar-1-6#toc1</a>
and <a moz-do-not-send="true"
href="https://www.opensips.org/Documentation/Script-CoreVar-1-11#toc1">https://www.opensips.org/Documentation/Script-CoreVar-1-11#toc1</a>).
Maybe something else is going on to make it 'work' in 1.6?</div>

<div> What I am trying to do is , I am
extracting "X-Info" from INVITE message and printing
it in logs in place of "$var(c)" . When an INVITE
message doesn't have "X-Info" header it prints
"<null>" in place of "$var(c)" in logs .</div>
<div><br>
</div>
<div><br>
</div>
<div> <b> This is working fine in opensips-1.6 .
For each and every call the $var(c) is getting
updated . </b></div>
<div><br>
</div>
<div> <b>I am facing some problem in
opensips-1.11 . For example : When I am doing a call
which has "X-Info" it prints the value
corresponding to that . In the next call , lets the
INVITE message don't have "X-Info" , for this rather
than printing "<null>" in place of "$var(c)" </b><b>its
printing the previous value .</b></div>
