3 months New to PBX and Seeking Advice

I’m the new IT Support Admin for my company and they have an existing PBX setup.

We have a PBX setup with Cisco phones and we would like to know if anyone knows of any free softphone software we could use for one user that lives in a rual area.

Any help is greatly appreciated!


I would start with this.


The first 4 on that list all work very well
