Hi Peter,

use an avp as holder for your string:

modparam("acc", "radius_extra", "User-Name=$fU; Sip-User-Realm=$avp(i:10)")

and

in routing script:

$avp(i:10)= "MYREALM";

regards, bogdan

Hello All! I've encountered some difficulties. I need to pass predefined string value ("REALM" actually) to accounting RADIUS server. I want to did it in way similar to:

modparam("acc", "radius_extra", "User-Name=$fU; Sip-User-Realm=$ar")

But I need to set realm for all radius-accounting requests to some value ("MYREALM" for example).

I tried set $ar explicitly before accounting this way

$ar = "MYREALM";

but failed with error "invalid left operand in assignment". Does $ar read-only variable? Another my try was to pass new realm value in module configuration section:

modparam("acc", "radius_extra", "User-Name=$fU; Sip-User-Realm=MYREALM")

It failed with message "parse failed in <Sip-User-Realm=MYREALM> around position ..."

I can't set up custom variable before route{} sections so I can't define my $var(realm) into module configuration line.

Are any ways to solve my problem exists?
