[Serusers] Change URI before accounting ?

I have something along the lines of the following,
provided with a few comments for easier
understanding. Enjoy! :)
modparam("acc", "multi_leg_enabled", 1) #Enable multileg support
modparam("acc", "src_leg_avp_id", 110) # Set the avp to save the src leg in $avp(i:110)
modparam("acc", "dst_leg_avp_id", 111) # Set the avp to save the dst leg in $avp(i:111)
# Under my INVITE handler I have:
#
# Set the AVP for ACC source leg, this is
# static.
#
avp_printf("$avp(i:110)","$fU");
# If the URI begins with "blabla", we
# account it by prepending shit and then
# the number as before. When we dial our
# PSTN trunk or whatever it is were
# dialing we strip a digit first.
#
if(uri=~"sip:blabla@) {
avp_printf("$avp(i:111)", "shit$fU");
strip(1);
} else {
# In all other cases we just
# account the URI as it is and
# pass it along.
#
avp_printf("$avp(i:111)", "$fU");
}
route(1); # Send it to our normal relay route
Perhaps not the best example but you should get
the hang of it.
In your acc table you should get a post where
src_leg and dst_leg is set to the appropriate
values. Note that sip_to and all that will still
be what you're used to, it's only src/dst_leg that
changes.
Regards,
Kristian.
