I'd think your goal at this point should be to simplify the config to the smallest possible config that can produce the questionable behavior, and then provide that entire config file (even better, implement this in docker compose, using something like sipp to emulate your UAs, so that the behavior can be easily reproduced by anyone). If the config is too big to reasonably present in an email, then just put the sample code on github.
Several points with the sample config you cite. This thread subject says that the error is with topoh enabled, but the code snippet presented provides neither module parameters for topoh, nor any call to topoh functions. Why are you asserting that topoh is the problem?
Your second line is a call to route(REQINIT), with no information on what happens in that route. While we can guess that it's the same as the default config file, there's no way to know for sure.
It's also not clear why the nat functions and add_path_received() are in this config as it relates to this problem.
Start removing all of this for problem isolation until you can identify where the problem is occuring. I'd also be curious if the error in question is really a result of parsing the ACK or if it's something else (trying to pull $ru off of a reply generates some kind of error like this I think).
Finally, although it's not the RURI, WHAT is with the scheme on the URIs in your To: and From: headers? 'Mailto"?

Hi Victor,
I tested 5.7.6 and 5.8.3 and got the same results.
At the moment request_route is very simple.
request_route {
xlog("L_INFO", ">> $ru from $fu\n");
route(REQINIT);
force_rport();
if(!ds_is_from_list()) {
if( !loose_route() ) {
if( !ds_select_dst(DEFAULT_ROUTE, "1") ) {
drop();
}
}
if (nat_uac_test("19")) {
if (method=="REGISTER") {
fix_nated_register();
} else {
fix_nated_contact();
}
}
add_path_received();
}
record_route();
forward();
}
This is the logs of ack
DEBUG: [1 90333697 ACK ...] <core> [core/receive.c:263]: ksr_evrt_pre_routing(): event route core:pre-routing not defined
DEBUG: [1 90333697 ACK ...] <core> [core/receive.c:474]: receive_msg(): preparing to run routing scripts...

Could this be a bug or did I miss something?

Hi,
I would suggest to try a more recent Kamailio version first.
