LineURI with Same Phone Number and Different Extension
This is acceptable, however there may be better ways. One big caveat to this approach is that if you ever accidentally assign the number without an ;ext= at the end, it will break calling for everyone all at once. For example, if you set that response group to have just tel:+1XXXYYYZZZZ and another user has the same number with an ;ext= at the end, Skype will send a 485 ambigous SIP response back and the call will fail. For the response group, you might want to use ;ext=0 or something or create a dial plan for the PSTN gateway to normalize the inbound call to match if needed.
Alternatively, everyone could get their own caller ID and you could just set a call mask on the outbound route to mask everyone's caller ID to the main number on the way out, nice and simple.
To be clear, "it will break calling for everyone all at once" I meant inbound calls to those that use the same number due to Skype not knowing where to deliver the call to.

Thank you for the added information. I have not done much with normalization of calls at this time. Our vendor who set it up did it for us. I will discuss with them the information you provided.
This might might explain why when I tried it a week or so ago it broke a ACD phone line.
Thanks again!

Yeah, I'm guessing that's exactly what happened. I don't like the ext= thing and reusing phone numbers, but that may be me being a risk-adverse consultant. The reason I don't like it is because even if I understand it, and the person responsible for the solution understands it, the new hire helpdesk kid setting up a user might forget. That new kid can easily mess up calling for a whole lot of people.
Anthony,
I did it again today. I went to our admissions department who has a response group set up which I did for them. They had an issue where student workers were calling customers back from student phones and the customers were calling them back at their numbers. I had the bright idea to change the LineURI to be the main number (which was the Response Group number) and ended up breaking all calls until I got it corrected. Basically, I had to go back and set back their LineURI to their number plus ext=####. So, after we had this discussion, I ended up doing it again and broke the response group until I got it resolved.
In our case, it is me that is setting this up for the campus. Hoping to eventually hand it off to someone else to do this set up and programming, but currently it is all me. So, when it stops working or I have issues, I am to blame. :)
