Chandu,
include/staff/newticket.inc.php
Find:
<tr>
<td align="left">Telephone:</td>
<td><input type="text" name="phone" size="25" value="<?=$info?>">
Ext <input type="text" name="phone_ext" size="6" value="<?=$info?>">
<font class="error"> <?=$errors?></font></td>
</tr>
And add comment marks so that it will be ignored, like so:
<tr>
<td align="left">Telephone:</td>
<td><input type="text" name="phone" size="25" value="<?=$info?>">
Ext <input type="text" name="phone_ext" size="6" value="<?=$info?>">
<font class="error"> <?=$errors?></font></td>
</tr>
Then do the same thing for clients:
include/client/open.inc.php
<tr>
<td>Telephone:</td>
<td><input type="text" name="phone" size="25" value="<?=$info?>">
Ext <input type="text" name="phone_ext" size="6" value="<?=$info?>">
<font class="error"> <?=$errors?></font></td>
</tr>
