We have CCM5.X with Pub &Sub. By taking Pub dow, all the phones,gateways are registering to the Subscriber.
But outgoing calls are not working.
MGCP gateways are pointing to the subscriber and dns is configured in the network.
One thing we observed, is the device pool of the device changes to Default group when they are registered to the subscriber.
utils dbreplication status shows every thing is fine.
Appreciate your response.
