I have configured cisco MCU 3515 with a gatekeeper. All my End-Points are registered with cisco 2800 gatekeeper. In the same way we crated a trunk between H.225 in a call manager 4.2 for gatekeeper. We can make video call without any porblem.But the issue is when we tried to make an audio call from IPT Phone we are unable to call in to the conferencing.
I am attaching screen short of MCU and Call Manager Configuration with Gatekeeper.
Please Let me Know if i need any other configuration.
