I am new to 3cx and am considering switching my entire house and home office to IP phones. I have installed 3cx and have configured the SIP settings for my provider (Viatalk). So far, I have two soft phones working. I am able to make calls from either phone with no issue. The problem I am having is that when an inbound call is received, it rings on extension 101, but not extension 100. I created a group 800 called "all phones" and set the inbound rule to send calls to this rule, but only the one phone receives the call. Can anyone suggest what I can check to correct this issue? Thanks, Nick ps - I also have a newbie question about using a PSTN interface, but I will create a new topic.
