CAS to SIP

I’m looking to deploy an all IP base paging system and want to connect it to a Legacy Voice switch we have at work. The Voice switch is only capable of CAS signalling and dedicated timeslots(no out of band signaling).

Is it possible to have a T1 time slot, when signaled by the rob-bit, initiate a predefined SIP number?

Example T1 time slot 1-24 would call SIP1-SIP24 extensions when the associated rob-bit is raised?

Is it also possible to go in the return directions where a SIP extension can be mapped directly to a T1 CAS time slot and raise the A bit on the return?

Thanks
