RV320 DHCP Empty

[YarivSade13769]

I have Cirsco RV320 , today i find that some of my VOIP phone does nor work properly i go into the RV320 and find that the DHCP table is empty ( you can see attched picture ) 

I restart the router twice and cant see the DHCP devices that on the network ,

all our end points on network do have internet we just have some issue with some IP phone and i think the empty table is the issue

 - That depends it seems that no addresses are being allocated at all 1) Is the RV320 your intended  DHCP server 2) Is the setup correct ?
