How to assign a form based on talk line used

Hello

We have multiple talk lines.  Is there a way to do the following?

• based on which line is called, assign appropriate form
• based on which line is called, automatically assign a tag
•  

For example, if line 1 is called, I want to assign Form 1 and have a tag on that ticket called Line1.

What I am asking is for incoming calls and not voicemails that are left. We have a team that answers the calls during business hours but I need to have the right forms assigned.

Thanks.
