Cisco IP phone is not registering to server

L2 Linker

Hi all,

I have Palo alto in my network connected to CISCO Call manager server and Cisco DX650 IP phone. I am facing issue that DX 650 is not registering to Call manager server when I capture log I found that the traffic comming from Call manager server and IP phone into Firewall is completing TCP connection but when outgoing traffic from firewall towards Call manager server and IP Phones is sending TCP (RST/ACK) message. I also have cisco 8811 IP phone which got registered so please help me with this
