You cannot have VM natively on CME. You need a CUE running on either of the following - 1. vCenter 2. UCS-E modules 3. Service Container If you have a lot of users and can justify cost for CUC, you can use that as well. ... View more

They both are very different products and cater different audiences & req. CMS is more of a on-prem conferencing solution, can be utilized as a CFB through CUCM, required for O365 interop (A/V/content) and dual homing etc. I don't see CMS being EoL'ed in the very near future. I don't see a replacement for this in the current product portfolio. CMS is being pitched and recommended as a replacement for what I would call previous gen solutions like TP/vTP, conductor, MCU etc. Curious though, what brings up this question in the first place ? ...

First thing, there is no requirement for trust list in your scenario since you already have a dial-peer with that IP address. It get's automatically added to the IOS trust list. Can you add "deb voip vtsp all" , "debug vpm signal" and "debug voice cc inout" and make a test call ? ... View more

"timeouts transfer-call" should be available for SIP CME i.e. voice register DN to be specific. Please check the CME command reference. The 78XX missed call issues affected a CME version running a specific phone firmware. What is the CME version here and the active load on the 78XX phone ? ... View more

Yes you can do that. Recommendation is always to do this when there is minimum traffic and/or after hours. Once you put the node(s) into maintenance, ensure registrations and calls clear up before upgrading. If they do not, manually release them. Incoming calls won't be processed once the node is in maintenance but existing calls will drop only if the node is restarted. Rest the peers in the cluster continue to process the calls. ...

Correct. The same router CANNOT be used for CME and as a CUBE simultaneously. If you need to run CME, you need a different box. You can use the current one for CUBE only. ... View more

1. SIP DN's default to 50 virtual channels. There is no concept for dual and octo like you have in case of SCCP. If you have to limit the channels, you can make use of "huntstop" channel and/or max-calls/busy trigger or a combination of both. 2. What timeouts are you talking about ? 3. Multiple extensions will work without any issues with SIP phones just like with SCCP if you talk from a user experience point of view. 4. There are some commands which are not available natively as part of SIP CME. You configure these under "telephony-service" which is SCCP CME and SIP portion of the CME makes use of it. ... View more
