We are using VG224 configured as MGCP Gateway. But we are not able to do conference in Analog phones connected to VG224. I have read on cisco website that Three party conference is possible when VG224 is configured as SCCP Gateway.
Can anybody guide me how to configure SCCP on VG224 to enable conferencing?
I have tried steps mentioned in below link.
But Gateway remains unregistered on CCM.
