Difference between CTI Route Point and CTI Port

In CUCM CTI Route Points and CTI Ports are often used interchangeably. 
However there is a difference.

• CTI Route Points are just used to redirect the calls but cannot terminate media.
• CTI Ports can terminate media.

Just as the name says, Route Points are used to route - in other words redirect.
Most IVR based applications on CUCM however use CTI Ports to enable Post Routing capabilities.
