Hi all, I'm trying to build an Active/Active OpenSer 1.3 cluster with 2 nodes. All it's working ok for the REGISTER messages throught the use of t_replicate and add_path, but I've problems with the INVITE messages. Both servers share the same location table on a PostgreSQL Multimaster cluster (but that's irrelevant, the PostgreSQL cluster I mean...), using db_mode = 2 An that's the logic I used: - On REGISTER ->> - Auth Request - NAT ? - add_path - t_replicate(oser2) - On INVITE ->> - Auth Request - lookup - Load prefs from DB - relay The problem I'm having is that the lookup function changes the RURI of the message on node1 BEFORE taking into account the "Path:" element present inside the AoR, so when the INVITE gets forwarded to node2 (where the NATed UAC it's registered), node2 deny the relaying of the message because $rD of the RURI it's not local (remember that the RURI whas changed on node1). Is there any way to know on node1 that the INVITE request MUST obey the "Path:" so I could to something like: $old_ru = $ru lookup("location") if(path_exists()) { $ru = $old_ru } ... t_relay() ?? Any other aproach ? Best regards -- Raúl Alexis Betancor Santana Dimensión Virtual S.L.
