I am currently using E1 trunk on cisco voice gateway (2911) to connect Telecom. Now I would like to add another E1 trunk as well as another router (2911) to increase outlines and redundancy. I am having two cucm cluster and using H323 between cucm & voice gateway.
Therefore, is this possible to configure new E1 on the new router voice gateway? It mean if the main router vocie gateway gose down, incoming calls & outgoing call will through second router voice gateway.
Thanks and best regards,
