hi we have 2 cup7.x nodes - when testing node failure we do not get presence status updates when the subscriber node is failed, i.e pick up the phone, i would expect the status to show 'on the phone'. When the same test was done with the Publisher node failing everything still carried on working fine.
This behaviour only started when we used SRV records on the CCM Trunks and the CUP gateways.
When I had this implemented without SRV records and was just using Host names, node failure test had no affect, everything carried on working fine(minor blips when clients connected to other servers etc). Any advise appreciated. By the way should the subcluster under cup topology also use an SRV?...cheers, Jeff
