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
For registration the CUCM should not necessarily need a rule as the Phone is the client.
Have your got logging turned on for your "default interzone" block??
Do you see any traffic from the phone?
Is the routing from the phone to the CUCM correct?
You will need a rule from the CUCM to the phone for SIP/SCCP, and perhaps the RTP traffic.
I HAVE 8 PHONES IN SAME RANGE FROM
X.X.X.200 TO X.X.X.207 SIX OF THEM ARE 8811 WHICH GOT REGISTERED SUCCESSFULLY AND 2 OF THEM ARE DX650 FOR WHICH I AM FACING ISSUE . FOR DX 650 TRAFFIC FROM IP PHONE TO PALO ALTO AND FROM CUCM TOWARD PALO ALTO ARE ESTABLISING TCP CONNECTION BUT TRAFFIC FROM PALO ALTO TO DX 650 AND TOWARD CUCM ARE SHOWING (RST/ACK) .
IS ESTABLISHING TCP CONNECTION
IS SHOWING 【RST/ACK】
