Hi Abdul, I dont think this delay is due to the TFTP server failover but the actual registration to secondary server when the primary is down. IP Phone usually sends keepalive messages to both the primary and secondary servers at the specified time interval as configured and failover happens if three such keepalives are missed. Please check the below link which explains this in detail: https://www.cisco.com/c/en/us/support/docs/collaboration-endpoints/unified-ip-phone-7900-series/200410-Troubleshoot-IP-Phone-Unregistration-A.html you can play with these timers based on the requirement and keep it at an optimum value. Keeping a very low value could result in unnecessary failover/fallback as the phones will register back and forth, HTH Rajan Pls rate all useful posts by clicking the star below

Hi Hari, If the two nodes are completely removed from production, then could you confirm whether you have deleted those server entries in System --> Server and rebooted the cluster once. HTH Rajan Pls rate all useful posts by clicking the star below

Hi Jonathan, Pub reboot is not required for changing cluster ID and not mentioned as mandatory in any of the Cisco documents. After changing the cluster id, you could verify by downloading a CDR report. HTH Rajan Pls rate all useful posts

Hi Shibin, Not necessarily if you use Best Effort Early Offer as mentioned below: Best Effort Early Offer [Early Offer support for voice and video calls Best Effort (no MTP inserted)] Best Effort Early Offer can be enabled on the SIP Profile associated with the SIP trunk, and it is the recommended configuration for all Unified CM and Unified CM Session Management Edition (SME) trunks. Best Effort Early Offer trunks never use MTPs to create an Early Offer and, depending on the calling device, may initiate an outbound SIP trunk call using either Early Offer or Delayed Offer. Best Effort Early Offer SIP trunks support voice, video, and encrypted calls. Best Effort Early Offer SIP trunks send outbound calls with an Early Offer (INVITE with SDP content) in the following situations: An inbound call to Unified CM or SME is received over a SIP trunk using Early Offer. An inbound call to Unified CM or SME is received over an H.323 trunk using Fast Start. An inbound call to Unified CM or SME is received over an MGCP trunk. A call is initiated from a SIP-based IP phone registered to Unified CM. A call is initiated from a newer model SCCP-based Cisco Unified IP Phone registered to Unified CM. Best Effort Early Offer trunks send outbound calls with a Delayed Offer (INVITE without SDP content) in the following situations: An inbound call to Unified CM or SME is received over a Delayed Offer SIP trunk. An inbound call to Unified CM or SME is received over an H.323 Slow Start trunk. A call is initiated from an older model SCCP-based IP phone registered to Unified CM. https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/srnd/collab11/collab11/trunks.html#pgfId-1342241 HTH Rajan Pls rate all useful posts

Specific protocol will be used for communication between CUCM and Voice Gateway. You could check on CUCM whether the gateway is configured with MGCP or SIP.

If possible you can get a packet capture from Phone used to make a call to have a look at the RTP streams. HTH Rajan Pls rate all useful posts

I dont think the CUCM needs to be in mixed mode for this. But you should have restricted version of CUCM for VPN configuration option to be available. https://www.cisco.com/c/en/us/support/docs/security/anyconnect-secure-mobility-client/116162-trouble-anyconnect-vpn-phone-00.html#anc3 HTH Rajan Pls rate all useful posts

Hi, By design you can eenable this only on one node but you can follow the workaround mentioned in the below link to use subs when pib goes down for redundancy purpose: https://community.cisco.com/t5/collaboration-voice-and-video/corporate-directory-redundancy/ta-p/3134583 HTH Rajan Pls rate all useful posts by clicking the star below and mark any accepted solutions

Hi, Both CUBE licenses are CME licenses are honor based and its a paper license. No need to install anything in CME but you have to keep it to get support for the product.
