Fix. Escape <> in all fields in CDR xml.

Browse Source 
When using redirect cdr also can contain e.g. `sip_redirect_contact_0` / `sip_redirected_to`.
I use `preg_replace_callback` to proceed all fields.
May be it more correct use urlencode because if we get xml with non UTF8 char we lost CDR.
```php
$xml_string = preg_replace_callback("/<([^><]+)>(.*?)<\/\g1>/",
	function ($matches) {
		// var_dump($matches);
		return '<' . $matches[1] . '>' .
			urlencode($matches[2]).
		'</' . $matches[1] . '>';
	},
	$xml_string
);
```
