i just wanna be sure before starting to action.
system is running based on mgcp. i mean network is already installed.
without using h323 , can i register same gateway router to callmanagerA and callmanagerB at the same time.
ccmA and ccmB are not publisher and subscriber.
i repeat they are different customers' callmanagers. they have lan connectivity in different vlans.
if one of the pri line fails ,can i use the other customer s pri line. I mean customer A can use the customer B 's pri ?
ccmA controls gatewayA , ccmB controls gatewayB.
What i wanna do is that ccmA should control both of the gateways, also ccmB should control both of the gateways for pri redundancy.
the only way is using h323?
thank you vey much
