Aha, so using an AVP as loop counter (I need the counter for the whole transcation lifetime) like:

$avp(count) = $avp(count) + 1;

would work (it does), but creates a new array element every calculation?

yes.

I guess the workaround to not create an array is to use always an index, at least on the left side, eg:

$(avp(count)[0]) = $avp(count) + 1;

The right would be: $(avp(count)[*]) = $avp(count) + 1;

btw: Is there a function to dump all currently defined AVPs, XAVPs and variables?

For avps:

Not sure now the one for xavps was exported to config, but it is available internally.

Hello,

AVPs are multi-value variables, so:

$avp(x) = 1; $avp(x) = 2;

Create a list with two values, the last added is first retrieved. You can use indexes to access them.

For example:

• $avp(x) will return now 2 (same as $(avp(x)[0]) )
• $(avp(x)[1]) will return 1

You can use variable as index:

$var(i) = 0;

then: $(avp(x)[$var(i)]))

To go through the list, you can use while(...) { ... } statement with an variable for index that increments in each step.

When there is no value for avp at that index, then the returned value is $null, e.g.,

while($(avp(x)[$var(i)]) != $null) { ... $var(i) = $var(i) + 1; }

Cheers, Daniel

There is nothing wrong with the carriers, so I wouldn't want to mark
them.  Just no route to destination type scenario.

I like daniels option with the drop on_branch.  Only challenge I
have is keeping a list of all the flags I have already tried.  Say I
have five carrier groups and I set the flags in gw to 1 2 3 4 or 5
respectivley.  How could I use an AVP to efficiently keep a running
list and then check against that list?

Thanks!
