Hi Experts,   Just want to confirm below queries:   1. Ephemeral Ports > For TFTP, from the Cisco's official firewall guide (https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/port/10_0_1/CUCM_BK_T537717B_00_tcp-port-usage-guide-100.pdf), Ephemeral ports (32768 to 61000) are indicated. May I know what's the purpose of this and if 69 and 6969 are sufficient ports?   2. Port 2727 > From Cisco's official guide, I cannot see this port anywhere. However, I read a couple of forums (ex. https://community.cisco.com/t5/collaboration-voice-and-video/mgcp-and-its-working-with-trace-example/ta-p/3155820, https://community.cisco.com/t5/collaboration-voice-and-video/mgcp-gateway-integration-with-cucm-and-pstn-service-provider/ta-p/3116588) that this is  used to send messages from the gateways to the call agent. Is this really needed or Cisco needs to update their guide? Thanks.   Regards, Flo   ... View more

Hi Experts,   CUCM: 9.1.2 New CUCM: 11.5   We are in the process of migrating our phones to our new call manager 11.5 - different IP and hostname - from call manager 9.1. We have 802.1x configured on the phone. Just wondering if we upload the cucm 9.1 capf and callmanager certs as capf-trust and callmanager-trust and phone-sast-trust respectively to cucm 11.5. Will phones still register? or is there any other way to register the phone seamlessly to cucm 11.5. Thanks.   Regards, Flo  ... View more

Hi Experts,    I just did a restore on my UCCX 10.X HA and the licenses are now invalid. Only seeing 3 tabs in CCX Administration also. I am planning to upgrade the system to 11.X. Before I proceed in doing the upgrade, I believe I need to fix the 10.X license first as the services are not totally UP.   Or can I proceed despite the license is invalid?   Please correct me if I am wrong. Thanks in advance!   Regards,  Flo ... View more
