Bogdan,

Thanks! This really helped clear up my understanding. I was reading everywhere that pseudo-variables are supported by AVPOPS but I did not realize that it only worked with a couple functions. I was able to get my script working fine with your example.

Hi Daryl,

you cannot use pseudo variable everywhere. To see exactly where you can use them, please read carefully the description of the avpops function's prototypes: http://www.voice-system.ro/docs/avpops/

For ex., in your case, move first the FROM URI username into an AVP: avp_printf("$tmp","$fU"); and them check the it against your avp: if (avp_check("s:myavp", "eq/$tmp/i")) {

do not forget to define the "tmp" avp alias (ex: tmp=i:13). See: http://www.voice-system.ro/docs/avpops/ar01s05.html#avp_aliases

First I want to say thank you to everyone for all the kind help I've received as I start to dig into OpenSER.

I think I'm starting to get a grasp of avps, as I've worked with SER for a while, but I am seriously struggling to understand the proper use of pseudo variables in OpenSER.

My thought was to try something like this...

if (avp_check("s:myavp", "eq/$fU/i")) { # do something here... };

I was hoping to match against the From URI username with the $fU pseudo-variable, but this doesn't appear to work. I read the doc but it's still pretty gray to me.
