I tried to set a connectivity between 2 CUPS but the system troubleshooter mark Invalid inter-cluster proxy domains, this is the scenario; both CUPS are in the same domain (in theory), my customer have 2 head quarters, in each office have a CUCM with CUPS and the users in both office can communicate each other, but I have 2 question at this point;
1. This could be a Inter-Domain Federation, (this is because one of the CUPS have no domain configured, I did not configure this server in office 1)
2. This is inter-cluster, if this is the way; I have few problems to do this because for any reason (I did not configure the CUPS in office 1) there is no domain specified in the configuration, as the troubleshooter say is not the same domain, I tried to change in System>ServiceParameters>server>Sip Proxy>Proxy domain, right now is set to PROXY_DOMAIN_NOT_SET, after I did the change and restart the Presence Engine, this parameter still the same. Then I went to CLI and checked the domain value, and have no domain configured, I configure the DNS and then set the domain, but I can not change the sip proxy domain value in the administration interface.
Any advice to force this parameter change. If need more information I'll be pleased to share.
Tks in advance

before: no domain set in the network, after: set network domain DOMAIN.COM
