I'm completely new to 3CX. I have been task with configuring our new 3CX to work with our existing Cisco 7940 phones. So I have all the basic setup. Now for the "fun" stuff... This new phone system is going to be used to support calls for 3 different companies (not the problem IVRs already set). But each one of our staff will have to make outgoing calls as well and in most cases will only need to use the caller ID from 2 of the 3 companies (which works for the 7940 as it only has 2 lines to choose from). So in the phone provision template for the Cisco 7940 i have the following settings for the two lines: #Line 1 Setting line1_name: "%%extension_number%%" line1_authname: "%%extension_auth_id%%" line1_displayname: "Comany A 604-555-1234" line1_password: "%%extension_auth_pw%%" line1_shortname: "Company A" #Line 2 Setting line2_name: "%%extension_number%%" line2_authname: "%%extension_auth_id%%" line2_displayname: "Company B 604-555-5678" line2_password: "%%extension_auth_pw%%" line2_shortname: "Company B" How can we use the line1_displayname and line2_displayname in 3CX as the Outbound Caller ID when a specific line is selected?
