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 ... View more

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 ...

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 ...
