1 MRA Expressway cluster with 2 CUCM Clusters but 1 domain

[ThanapongHongpakdee24797]

My client has 2 different CUCM clusters which are

1. CUCM 12.5 Cluster A (CUCM Pub, Sub1 & Sub2)

2. CUCM 12.5 Cluster B (CUCM Pub, Sub1, Sub2 & Sub3)

and 1 expressway cluster (Exp-C Pub, Sub & Exp-E Pub & Sub)

Both CUCM clusters want to use Jabber MRA but my client only has 1 domain, let say it is "ABC.com" (not prefer sub-domain)

How Can I setup this 1 Expressway cluster to serve both CUCM clusters with 1 ABC.com domain ?

Please help !!
