Hello,
I have a problem: When someone begins a call from PSTN to my voip
network, the session interrupts after 30 secconds. The UA don't receive
the ACK message(6)[the ACK doesn't arrive].The scheme below indicate this
situation.
P.S. This situation happens just with one type of equipment: atcom
AG468; with other equipment (atcom AT320ED, audiocodes, atcom AG168)
all works fine.
Very strange.
Thunks.
