I've just recently purchased a 2951 voice gateway but unfortunately can't configure it in my current version of UCM (7.1.2), it's not an option in the drop down list of gateways. I've read quite a few posts here and from what I understand, I need to upgrade to version 7.1.3 in order to gain the 2951 option. My only concern in doing this upgrade is firmware upgrades on the phones. I would like to prevent upgrading the firmware on all the phones if at all possible. Our current version of 79417961 phones is SCCP41.8-5-2S and the default for version 7.1.3 is sccp.8-5-2SR1. My question is which one is, will my phones go through a firmware upgrade?
Thank you in advance for your input.
