How do I get 2 different lines to ring into one Aastra phone using FreePBX?

I have 2 business and so therefore have 2 #'s. I want my one DID to ring line 1 on my phone and I want my other DID to ring Line 2 on my phone.
How do I do that?

Thanks in advance!

Set up each line with a separate extension/secret that corresponds to the DID numbers respectively.

I understand that but how do you get that extension to show up on the phone.



Depends on the phone, but you simply program extension 2 exactly as you did extension 1 using the credentials for extension 2.
