IPDect R4 call disconnected adter two minutes

[ista4]

I installed a server edition on 10.0 SP2 with IPDect R4 on 7.2.24
All calls on IPDect are disconnected around two minutes.
I get an error in monitor like this:

PRN: H245RTDSE --- Round trip delay timeout expiry, clearing call

Fixups are turned of in the firewall.
Is there anything else i can do to fix this issue?

I wonder if your 9.0.10 edition of IPOffice doesn't match your IPDect R4 on 7.2.24 firmware and they are not compatible. I'd review if your version of IPOffice is compatible with the IPDect 7.2.24 which is the latest release.

The server edition is running 10.0 SP2 and not 9.0 and yes it is compatible.
The problem vanished so i wonder if the network guys did something.
For now it seems to be solved.

Network Magic, my favorite solution to everything!
