Hi all, The main problem I found when testing HA setup was as following: If master host fails, all established calls can not be correctly terminated and can not be transferred. The problem (as I understood it) was that sipx sets Record-Route header, pointing to master host IP ADDRESS and not to dns name, which is common for both master and distributed/slave host. And all UA's will send re-Invite and Bye messages to Master host IP address.
I asked about it in the list, and was answered that it is not possible to use dns name in the Record-Route header because of the problems of some widely used phones (I don't remember which phones were mentioned). So the question is: does 3.10.3 HA sipx still use ip address in Record-Route header? And what about 4.0? If not, could it be a configurable option, so sipx will use dns name in the Record-Route header but only for UA's that are known to work ok with such header? Regarding the overall impression of HA system: HA system imposes some requirements on the phones. Media services are still not redundant, auto-attendant, voice mail, ACD announcements will not work when master fails. BTW, does 4.0 somehow improve that? The most critical "points of failure" are disks and network interfaces, which can be made redundant using operating system capabilitites...
