I'm putting some phones statically into CER and I have a line number that is on two different phones, the phones are at two different building locations. Is there a way to put both phones into CER with the same number but have the correct information be pulled up when dailing 911?

Hey Jacob,
Yes, by using ERLS and ELINS and not using the number assigned to the phone.
ERL ties the switchport to a physical location and the ELIN is the number that the PSAP sees as the caller-id and can call back the 911 caller if call is disconnected. I have never seen the DN on the phone used as the ELIN.
See link below.

Not when you defined manual phones, the question is why are you adding them manually? Are these analog devices? If they are IP phones you can either do port tracking assuming Cisco supported switches or subnet tracking.

I'm not adding all the phones manually, there's just some that the company wants manually added.

Got it, you can only have unique manual phone extensions defined, so you cannot have the same extension assigned to 2 different ERLs. If one it to be build manually and another one is tracked then CER uses the following order to figure out which one to use:
Emergency Responder directs emergency calls based on the location of the phone from which the call is placed. The location of the phone is determined by the following methods, in order of precedence:
