So, this is on the Voice --> Line 1 settings. Do we also choose "JitterBuffer Adjustment" to yes?Then, on preferred Codec, do we also set "Use Pref Codec Only" to yes?
I'm interested in this as well. Although we use a SPA112 instead of 122. We also would like to know if there is a way to burn in the ACS url into a firmware image so that the technician doesn't have to change this.
