Mario,
Thanks for your reply. I think I get the majority of what you are saying.
I am pretty sure the I can get it based on your response as my requirements are not as broad as yours.
If I set the effective caller id name and number to the external values and then use
sip_h_In-Reply-To=${sip_call_id} for the internal extensions in the dial-string, I think I am good.
I was wondering if I could set the channel variables for caller id in the dial-string with {} or in this case []?
That of course leaves the political debate of how long to delay for VM (call_timeout=) and
[leg_delay_start=] for the cell phone connection (attempt).

I do exactly that and more. First, see this page for what the caller hears: https://freeswitch.org/confluence/display/FREESWITCH/macOS
I replace the early media ringing with custom prerecorded messages that includes the caller name.
The I bridge with the parts below built from a LUA program. The called cell phone displays the callerid of the original caller (that took a year to figure out).
What you are after is "sip_h_In-Reply-To=${sip_call_id}”. But… keep two things in mind: First. Your ITSP must support it, in my case I use Callcentric and you MUST inform them you are doing this so they can turn it on for your account.
Second, the biggie: with stir/shaken (https://www.fcc.gov/call-authentication) coming up I don’t think this will be possible anymore. See my comment below.
{originate_timeout=48,alert_info=<http://127.0.0.1>;info=Family}${group_call(deskphone@${domain_name}+A)},${group_call(iPads@${domain_name}+A)},${group_call(iPhones@${domain_name}+A)},[leg_delay_start=24,leg_timeout=24,sip_h_In-Reply-To=${sip_call_id}]sofia/gateway/${dial_gateway}/12121234567,[leg_delay_start=24,leg_timeout=24,sip_h_In-Reply-To=${sip_call_id}]sofia/gateway/${dial_gateway}/12127654321
More than you asked about but important to note:
Because of problems below (there are more) bridging to a cell phone, I am trying something different and if it works will put it in the wiki. Instead of bridging the call I want to make the cell phone a simple Freeswitch extension. That
resolves all the problems including passing callerID. This is done using VPN and a SIP app, in this case Bria for iPhone which uses Apple Notifications to trigger the app when a call comes on. Only problem is… VPN on demand does not work with Bria because
it uses sockets instead of the recommended Apple API. So I have been trying to convince Counterpath to add one DNS lookup to trigger VPN On Demand. This solution would be 1000 percent better than bridging.
Problems with this method:
