[cisco-voip] Gateways and two clusters

[Ryan Ratliff]

After your DMA if you have your servers in System->Server by IP  
address make sure you change all of them (even subs).  Saw an issue  
recently with a "lab" DMA cluster had mrdia resources trying to  
register to the 4.x subscribers because they old IP addresses were  
still in the database.

So you should be ok, I was in the same boat as you, but I rebuilt my  
main MGCP into H323. But I did have my MGCP gateway pointed to the 4.x  
with  a ICT that forwarded calls to the 7 for testing

I have our new CUCM7.0 media on the new hardware in our lab, and the  
existing CCM4.1.3 in production.  After I run the DMA I would like to  
place calls and test the new CUCM before placing it in production.

My question is this:  If I run DMA the gateways will be added as  
before (H323 and MGCP) but as long as the Gateways themselves get  
their MGCP config from the CCM4.1.3 server there shouldn't be any  
problems, right?

I can set up some H323 calls to the gateways on the CUCM7 server and  
test call connectivity, routing, quality and features (hold, park,  
mobility) without affecting production calls....right?

Just checking before you know, I have to put the stuff from my desk  
into a copier paper box and get escorted from the premise...
