HDX can't initiate calls

Hi all,

I have a group of working HDX within my organization. We have integrated our Polycom platform with the IP Telephony.We recently upgraded our platform from the CMA to DMA to enable us utilize the two RMXs by cascading both. For this cascading to work fine, we had to create the VMR on the DMA and keep the VMRs on the RMX as backup(note that there is an existing trunk between the DMA and Cisco CUCM). All has been working fine until recently. Now I observe that neither the Polycom nor the desk phones can initiate meetings on the DMA, except an RPD initiates first. I would appreciate any assistance
