Hello Telleraine,
welcome to the Polycom Community.
The only quick way would be pointing the phones to a provisioning server and let them load a modified configuration.
Our phones always place a call on Line 1, there is no way to change this.
You would need to swap the registrations so Line 1 becomes Line 2 and vice versa.
For the Line 1 Key automatically dialing of *75 you would need to elaborate a bit more.
- Do you need the Key just to dial *75 when pressed or *75 and then something else?
or
- Do you need the physical key to dial *75 and if someone dials something automatically add *75 ?
The community's VoIP FAQ contains this post here:
Nov 4, 2011 Question: How can I change the functionality of an Hardware Button?
Resolution: Please check => here <=
Above explains how to assign a Speed Dial to a physical key which then could dial *75 automatically.
You could also use the dialplan.x.digitmap and set it for dialplan.1.digitmap to add for registration 1 (Line 1) to always add *75 to any number dialed.
The digitmap is explained here:
