Caller ID Restrictions

[gbh2o]

I think you should probably separate the issue as related to residential from Express handling.

I also have to consider multiple things when I route calls from my * boxes. Although this is just a hobby for me:

My daughter in NY has an assigned DID, but dials outbound through _an_ available trunk prioritized and selected on several factors. Her husband in VA has no DID, but has a system extension; he dials outbound through _an_ available trunk prioritized and selected on several factors. My mother in FL has POTS, but uses a local DID to call family on extensions, and has DISA access as well. My mother-in-law has POTS and accesses DISA via a local DID as does my wife when she needs to make a personal long distance call while at work. The rest of my family around the country has a variety of extensions and local DIDs to communicate with internally with each other, but are generally expected to use their own POTS for their long distance. I don't need to pay for their freight, they earn their own living and can afford it. The one exception is that I generally allow them to place personal calls to family members overseas through my system since I have a variety of cost-effective routes [and some extensions] available.

So is it better to reflect a caller ID associated with some varying outbound trunk, or to attempt to pass through the CallerID info if received from the call initiator, or perhaps one by which the caller may currently be directly reached, POTS, cell phone, etc.?
