Hello all,
I'm trying to use Callback feature over an ICT without success. I get "Callback cannot be activated on" message.
While on the same cluster everything is fine; I cannot make it work between different clusters.
Does anyone got some hints or a similar experience?
thanks

Unless you're talking about a QSIG enabled ICT then it's expected to fail

i fixed it by adding QSIG support under tunnelled protocol on every trunk.
it's working.
