Phone vendor trying to blame the data network

We handle the data networking and infrastructure at a client. The client is having phone issues. Their clients sometimes cannot call in sometimes and lines are dropped. We have never had an issue calling and have not experienced the issue. There is a separate company that is handling the VOIP system. The phones are mostly on their own wiring and subnet except for one PC(we are running a cable to fix that) . The subnets are routed together on the firewall, though DHCP is not routed.

I test the DHCP on both sides and it resolved properly. The VoIP PBX is the DHCP on the phone subnet. The phone vendor is a bit hard to work with. I asked him for Packet Captures and sent this to the client. Sideways and everything.

He is saying there are DHCP error on the network and blaming the data network. All the phone register. It looks to me like the PBX is not set up properly. Is the VoIP vender trying to smoke screen the client with this screen shot?
