How can we get 1 channel for each user to be able to always have a simultaneous call ? For 12 users, only 4 SC calls always reaches limit and calls get dropped without even reaching IVR. I am new to 3CX, please help.
If what you want is to get more SC, then you need to speak to your provider to buy a larger license (if you require) and then upgrade your license in your 3CX Customer Portal to a larger SC. In your Customer Portal, select My Subscription then Upgrade. You should see something like this below:
Set also Sip provider channels in accordance with 3CX License SC. If you upgrade your license to 8SC on 3Cx side , be sure to subscribe no more channels on SIP provider side.
