Set up Bitrix24 voip suite with FreePBX sip trunk

Hello, I need someone to help us by setting up an inbound call center using Bitrix24 dialer. We have our own sip voip trunk and can also host freepbx vps if needed. We need to achieve the following call flow: Customer calls —> pbx places call on hold while waiting for InGroup member to be available —> once InGroup member is available call is routed to them in the Bitrix24 dialer. Inbound and outbound calls must both work. We need to be able to have multiple agents taking simultaneous calls and multiple customers waiting on hold for InGroup members to take the call. Must be able to play music on hold. We need Bitrix24. I do NOT want anything else such as vicidial or goautodial.
