Two lines on OBI202 -- CallCentric 911 service

Wow, that is excellent information, Steve -- I think I'm starting to understand!  Thanks yet again!

So, Robert (thank you!) gave directions for using two separate DID numbers, and using the "Called Number" parameter to route calls to the appropriate Extension/SIP.  That sounds like it would accomplish it just fine, but just to be sure I am completely understanding this:  rather than setting up two DIDs on one CC account, would the following work, as well?

The CC account has a single DID, with two extensions:  100 (default) and 101. Extension 100 is assigned to line 1 on the Obi for incoming calls, and extension 101 is assigned to line 2 on the OBI for incoming calls.Both Google Voice numbers (personal and business) are set to forward to the single CC DID number.I create two call treatments in CC based on the "Call coming from Caller ID" parameter:  any calls coming from the personal Google Voice number are sent to ext. 100.  Any calls coming from the business Google Voice number are sent to ext. 101.
That all seems logical to me based on what you've taught me -- but that last bullet is where I'm still unclear.  I don't understand if CC will "see" the Caller ID of a call forwarded from Google Voice as the Google Voice number (which will make the above scenario work) or as the number of the person who initiated the call (in which case, the above scenario would not work, because those call treatments would be useless.)

Yes, that's exactly right.  And, outbound calls to 911 will simply work, because they are using your CC account, regardless of the caller ID / DID used to place the call.

The CC call treatment setting uses the caller ID of the CC DID being called, not the caller ID of the number of the caller, regardless of whether it is a direct or forwarded call.  Imagine you have two baskets:  one is labeled "apples" and the other is labeled "oranges".  You have a rule:  all apples are given to Jane, and all oranges are given to John.  It doesn't matter if a Granny Smith or Fuji or Gala apple is put into the apple basket -- Jane gets them all, because that's the rule.

Lyle:
I think we're talking past each other on this one:  I understand that using two DIDs on one account would work.  But for my own edification, I was trying to see whether I could accomplish the same setup with a single DID number (third bullet) by using call treatments based on the Caller ID of the caller (4th bullet).

You said that CC treatments use "the Caller ID of the CC DID being called" -- which is true if I use the "Called number" criterion, as Robert suggested (arrow 'A' in the attached image).  What I was suggesting, on the other hand, was using the "Call coming from Caller ID" criterion (arrow 'B' in the attached image).  That option appears to give me the option of routing calls based on the caller's Caller ID -- but given that I have GV in the mix, I don't understand whether CC will receive the Caller ID of the person who initiated the call, or the Caller ID of the Google Voice number forwarding the call.

So, let's say I have my setup with one DID and two extensions as I laid out in my bullet points.  Jane (CID: 111-111-1111) has a hot deal on some apples and calls my business GV number (222-222-2222), which is forwarded to my one CallCentric number (333-333-3333).  I have a call treatment at CC that says "Send a call coming from 222-222-2222 to extension 101" (which is registered to line 2 on my OBI).  Will Jane's call ring line 2?  Or will the treatment fail in this situation, because CC sees the call as coming from 111-111-1111?

SteveInWA:
Oh, I see what you're saying now, sorry.

Yes, you can make that work.  Your question is what phone number (caller ID) CC will "see" for the inbound call, because that will determine if the call treatment will work or not.

The answer involves a setting on your Google Voice account.  GV lets you decide if forwarded calls display the original caller's number, or your GV number.  The latter choice is useful for your scenario.  Of course, the trade-off is that you won't see the calling party's number, but if you can live with that, then it will work.

The setting is here:  https://www.google.com/voice#callsettings

I just assumed you were asking about a two-DID solution based on your previous discussion and Robert's answer, and I didn't carefully read your new proposed scenario.  Frankly, I would rather have two different DIDs for the flexibility of having two numbers (business and personal), and then you don't need to do the "use my GV caller ID" technique.  I have a total of 4 DIDs on my one CC account -- two paid local numbers, and two free NY numbers, and call treatments and extensions to route them to various phones.

Lyle:
Aha!  That makes perfect sense.  And I agree, going with multiple DID numbers is the better method so that I can see the caller's Caller ID.  (After all, Caller ID is one of the reasons why I went to CC in the first place!)

Well, Steve, it's been a pleasure.  You have been extremely helpful, and I have learned a lot.  I really feel like I have my head wrapped around the basics, now.  THANK YOU!
