I have multiple Kamailio instances using dispatcher using alg “7” - hash over the content of PVs string, both using the same dispatcher list.

Is it reasonable to expect both Kamailio, given the same hash_pvar, to select the same host from the same set? 

Looking at the source I do not see any reason why not, but I am getting different results from the two Kamailio servers. The only difference between them is different minor version numbers - 4.3.4 and 4.3.7

I want to ensure that calls with the same hash_pvar value go to the same backend no matter which Kamailio processes the request.

Thanks!
