Now together as
I have two PTC V4.1.5-201 and paring with GS500 V4.1.5-180072.
Frequently, the user can not control it, he can not hang up a call and access to the directory.
We need to retsart the PTC to resolve this problem.
Can yous please help me.
I had same problem with TouchControl paring with Real Presense 500.
The cause was the RealPresense before NAT gate.
And we've found the simplest solution - joining RP and TC into same network. That solved our problem.
