LineURI with Same Phone Number and Different Extension
One other question or clarification. The number I will be doing this with is a Response Group. I wanted to confirm that will not cause an issue by having the Response Group have number ###-###-1191 and then set six phones so they also have ###-###-1191 as their LineURI.
The reason I ask it that I tried to do this with another set of phones a week or so ago thinking this would work. I caused that number to stop working. The difference, the other number I was dealing with was a ACD using Clarity Connect. Again, trying to make sure I will not cause any issues by doing this process on a Response Group and phones in that Response Group.
Thank you!

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.
