Hey Sergey,
Let me start with a question: Are all your extensions in one location, or in multiple locations?
Regarding your first requirement, if your DID is registered as a trunk on PBXes, inbound calls to it can be routed to your land-line via another SIP trunk. Depending on how your Inbound routes are setup, inbound calls can normally ring on one or more SIP UAs and when in fail-over mode ring on your land-line.
The above scenario can be implemented without the direct involvement of your TalkSwitch, if and only if your DID provider supports concurrent SIP registrations. If they do, the incoming calls will be send concurrently to both PBXes and the TalkSwitch (SIP Forking). Under normal circumstances, calls will be answered by the extensions registered to the TalkSwitch, but when it is no longer reachable, the calls will be delivered to your land-line via PBXes.
If the above feature is not supported by your DID provider, you might be able to try a few other techniques, if they are supported by the TalkSwitch.
Regarding your second requirement, it really depends on the SIP User Agents (soft-phones, ATAs, IP-phones) you are currently using. If they support multiple registrations, routing calls via multiple VoIP providers though PBXes is trivial. If they don't, things get more complicated, but there should be a way to achieve that, if you are willing to alter your setup.
Have a good day.
