[OpenSIPS-Users] Slight problem routing 100s and 183s

[Bogdan-Andrei Iancu]

Hi Nick,

if INVITE goes .11 -> .5 -> .10 -> .20 -> .122, why the 100 reply from
.122 goes to .5 ??? replies have to be relaid back exactly on the same
path as the request.

So, the 100 reply from .122 must go to .20, not to .5 !!!
