Kamailio can't parse construction like $(hdr(History-Info)[*]{param.count,,}) where
delimiter is comma.
I tried to use delimiter as , / ',' / "," wuthout success.

Can you try storing the delimiter in a variable (eg. $var(...)) and provide the variable
to the transformation? It could be a quick around for now.

Unfortunately, this doesn't work:
```
$var(delimiter) = ",";
$var(count) = $(hdr(History-Info)[*]{param.count, $var(delimiter)});
```
```

Is there a whitespace before the variable?

Yes, there was whitespace. I tried without whitespace without success.
```
$var(delimiter) = ",";
$var(count) = $(hdr(History-Info)[*]{param.count,$var(delimiter)});

OK, it seems this needs more investigation.
Meanwhile, maybe you can use other function or transformation to replace the `,` with
another character and the count.
On the other hand, if you just want to count those headers, probably you can do a while
loop to check how many headers are.

Can you try with latest 4.4 branch? I pushed some commits to fix the use of variable for
separator.

Unfortunalty param.count still can't accept comma (,) as separator.
Code block:
```
if ($(dlg_var(cgrSuppliers){param.count,,}) > 0)
{
}
```

Have you tried with variable?
```
$var(delimiter) = ",";
if ($(dlg_var(cgrSuppliers){param.count,$var(delimiter)}) > 0)
```
