Two UCM's with one network

Hello

Has anyone been able to get two UCM’s to work on one network? I can get them to work if I change the RTP ports on UCM #2 to 20000-30000. But of course, I have no sound. I’m not looking to create any local extensions on the second UCM, I am only looking to create remote extensions.

Let me know please if anyone has successfully done it.

Thank you very much!

Sorry, I should have been more specific. I am not looking to do a HA setup, I am looking to just have two ucm’s on the same network, plugged into the same switch. They are not connected to each other. I am looking to only have remote extensions setup on the second ucm. To give you a background, I am going to have some customers using remote registrations on the second ucm. Customers that are one or two extensions.

As Larry has pointed out – it will work. Is the problem you’re having with ZeroConfig or what’s the issue?

Thanks Larry. I altered the second UCM to use RTP ports 20000-30000. I thought each ucm had to have a different range. Are you saying you did not alter the range?

I will try again with the most up to date firmware. Let me know about the ports, or if you had to change any other ports to get the others to work.

Why would you change the FTP ports? I don’t do that when they are in the same network. Can you tell us what the problem is?

I will try the firmware update. Thank you

I did not change FTP ports. My original post states that I changed the RTP ports, and this was change was made under the direction of grandstream support. I believe though, Larry and I are reaching a satisfactory conclusion.

Thank you for following up.

I had not changed the FTP ports, it was the RTP ports.

There shouldn’t be any need to change the RTP ports – I accidentally put FTP and didn’t catch it.

I got it. Thanks so much!

Yes, it did help. Thank you!
