Problem with CS - call servers, both CS are in main status!?

Hello, could someone help me?

I have an AL OXE IP MG R.11.0.1 with a duplicated CS configuration in two different subnets and in different locations, a few days ago I noticed that CS, xa and xb are not visible and both north are in "main" status. I restarted xb but it always goes back to "main" status. The phone app works normally. I checked the network parameters on both processors and they are all set correctly. How to bring the system to a normal state, so that xa server is in "main" and xb is in "stand-by" status?

Both can only be in a main status if they can't see each other anymore.
That s a network issue on your end. As soon as they see each other, one will reboot to go back in standby mode.

Thank you Mr. Frank,
first I checked the network itself, when I telnet on xb (which should be stand-by) the processor can ping xa (Main) and vice versa with xa I can ping Xb. With the command netadmin -m sa the network parameters were checked and all are OK. Everything seems fine, but the processors are still not visible.

do you have a license installed?
is auto start on?
are the phone applications up and running?
What does the command 'twin' shows?

Yes, Dear Mr. Frank, I have a license, the system has been in operation since 2010, autostart is turned on, the phone application is up and running on both processors.

For xb011001 (twin command) - CPU address : Not Declared?

So your CPUs in different LANs.
Looks like UDP blocked between your CPUs.

acamup · Post by **acamup** » 27 Sep 2024 06:25

Yes, dear Mr. Alex, the Dual Processors (CS) of my PBX are located in two different networks and have been for several years. They stopped seeing each other a few days ago.
I checked with iperf applications running on computers in the same networks and UDP is not blocked.
Thank you for your suggestion.
