I have a Cisco SPA504G at my house, running across a VPN to our 3CX system at my office. Last night, I configured Line 4 to use a personal SIP account that I opened to replace my home phone. It worked great, but when the phone re-provisioned at 2:00am, it changed the Line 4 button back to match 1-3. When I login to the phone, the profile is still there under "EXT4". When I go to the Phone tab though, Line Key 4 has been changed back to "1" instead of "4". I can't find any reference to this in the provisioning template. It appears to have only "Profile 1". It also seems that if I modify the template, it will put this account on everyone's phone. How do I keep the nightly provisioning from changing this setting back?
