I have Ipad Pro with OS 13.3.1.
RealPresence Mobile (3.11.1-72381) drop calls H.323 after 12 minutes when calling trough VPN.
It dosn't matter if it's poin-to-point or RMX call.
It doesn't matter if I register through RM or directly to DMA or without any registration.
When call drops, VPN and Ipad registration continue be active.
In DMA log there is "H.245 end session command" from Ipad.
H.323 calls without VPN goes normally. With SIP calls everything's OK.
On ipadOS 9.3.x I don't have this problem.
