I have a Polycom 650 that is currently up and running. The user has created contacts, set line key preferences, etc. After the phone had been in use for a week, the user noticed that the handset volume returns to the default after every call, which is highly annoying. With a little research, I’ve learned that I need to change the voice.volume.persist.handset setting in sip.cfg.
I’ve been manually configuring phones up to this point. (I know that’s bad practice, but my justification was: multiple locations, difficulty getting tftp in place, and a history of Linksys phones that are simple to configure via the web interface. With a couple Polycoms in the mix, I’m starting to think a proper provisioning system is in order.)
My question is, is there a way for me to change just a single setting on an otherwise configured phone? If I have to re-enter things like server settings, that’s fine, but I’d really like to avoid wiping out the user’s personalizations like local contacts, speed dials and line key settings. Thanks in advance for any advice.
