I can not reproduce the problem, either with redis or DB. It sufficient to set the xavu in the request_route.

Pretty default cfg with the following additions:
```
root at kam03:/etc/kamailio# egrep "redis|topos"  kamailio.cfg-2852
loadmodule "ndb_redis.so"
loadmodule "topos_redis.so"
loadmodule "topos.so"
modparam("ndb_redis", "server", "name=srv1;addr=localhost;port=6379")
modparam("ndb_redis", "init_without_redis", 1)
modparam("topos", "storage", "redis")
#modparam("topos", "storage", "db")
modparam("topos_redis", "serverid", "srv1")
modparam("topos", "contact_mode", 2)
modparam("topos", "xavu_cfg", "tps")
modparam("topos", "xavu_field_a_contact", "a_contact")
modparam("topos", "xavu_field_b_contact", "b_contact")
modparam("topos", "xavu_field_contact_host", "contact_host")

request_route {
[...]
        $xavu(tps=>a_contact) = "A-side";
        $xavu(tps=>b_contact) = "B-side";
[...]
}

```
