Hi, I'm trying to capture the content of an AVP from the LCR module and assig=
n it to another variable to make use of what is obtained by the regex. For th=
is, I have used the avp_subst.

The content of $avp(i:709):
1|sip:|0|||2416027840||5061||;transport=3Dudp|11|1

I need to extract the index that indicates the port "5061" at position 8.
I haven't been able to achieve this by trying several regex patterns.
Has anyone experienced something similar?

Thanks!

Hello,

If the input data is somehow well formed, you could use the following transfo=
rmation to split around the pipe character for example:

Hi Henning thanks for your response, solved!

For my case exposed:
1|sip:|0|||2416027840||5061||;transport=udp|11|1

Filter
$avp(port_lcr_gw) = $(avp(i:709){s.select,7,|});

verbose:
NOTICE: <script>: splited: 5061

;)
