Soundpoint 330 LIne 1/2 Special setup

Greetings All,


New to the boards, but I did a quick search and couldn't find what I needed...


I work at a call center consisting of 75 Soundpoint 330 phones. While the phones work, and everyone seems to not have any real issues with them, I was hoping there was a "quick" way to make a config change...


Each phone has 2 lines, that connect to 2 different PBX devices. Line 1 connects to 10.1.1.x and line 2 connects to 10.1.2.x. Line 1 is used to access a predictive dialer and Line 2 is a general pbx for regular inbound/outbound manual calling.


the problem I have is that when a user goes to dial a phone number manually, it defaults to line 1, but that device does not allow outbound calls, and only logs the agent in/out of the dialer.


So I want to know if there was a way to make:


Make Line 2 the default when dialing a number from the keypad.

Make Line 1 automatically dial the key combination *75 when the button is pressed.


I do not utilize a TFTP server, yet, but that is in the works when the other half of the company switches over next year, as that would make it a total of 200 phones, and I really don't feel like provisioning all of them by hand... The 330's were already provisioned when I started working here.

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?
  • 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:

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:

Thanks for answering me. I was afraid that the best solution would be a provisioning server... I will take a look at the two articles you attached, just in case though.
