[BALAMURUGAN SINGARAM]

We need to add IP Phone 8841 in CUCM 9.1.2, in CUCM 9.1 8841 IP phone is not available. so we are upgrading the firmware for 8841 - https://software.cisco.com/download/release.html?mdfid=286255327&release=10.2%281%29&flowid=54174&softwareid=282074288

Please confirm it is right firmware  ?  also we need to do the upgrade activities in both PUB and SUB or upgrade PUB alone it is enough ? Please advice.

Because that's an iso file while dev pack is a cop.sgn

Hi Carlo,

After upgrade to latest release in CUCM 9.1.2.14900-14, I am not able to upgrade the device pack

cmterm-devicepack9.1.2.11003-1.cop.sgn or cmterm-devicepack9.1.2.15107-1.cop.sgn. I am getting the below error: Unable to mount the local file system. This could be caused by a corrupt ISO file. For example, FTPing the ISO file to the remote server in ascii mode would cause this error.

After upgrade to latest release we are able to see device 8841, best pratice to upgrade the CUCM to latest device pack also, please advice.

Hi.

I've already answered you on your other post.

You need to upload it to cucm via FTP/SFTP and NOT mount the iso file as virtual CD on VMWare.

Please try it and let me know.
