I have a new IPCCX 3.5 with CCM4.2 install. All cti ports and cti point are registered. When I dial the cti route point the first call connects to the agent. Then when dialing the cti route point every other call fails and drops.
I can see the cti port numbers on the phone as they increase. All ports configured the same.
Only if a dial them fast if I wait a few seconds the call goes.
