[Users] avp concat

[vallimamod abdullah]

Hello list,

I have 2 avps containing a username ($avp(s:usr))and a domain
($avp(s:domain)) retrieved from db and I would like to build an uri by
joining this 2 avps with an '@' in the middle.

I have checked avp_subst and avp_printf but it doesn't work as, for
what I have understood, they only accept pseudo variables (and not
other avps) for the replacement. For example,
avp_printf("$avp(s:uri)", "$avp(s:usr)@$avp(s:domain)")
is not valid.

Is there a (simple) way to achieve what I want (I am using version
1.1.0-notls) ?

Thank you,
-vma
