Port 5000 - 59999

For Video conferencing I have been requested to open the ports between 5000 - 5999 for both TCP & UDP.
Would like to know if these ports are opened in the firewall is there any security risks.
Does these ports have any security vulnerability.

We will be opening these from inside to outside which means from our IP to the external party IP Address.

Is there any vulnerability or security risk if we open these....
Watch Question

Since you are only allowing port access from internal to external, there would be no security risk. It would also seem to require traffic back into to network to complete the teleconferencing communication unless you are 1) only transmitting audio/video; and/or 2) sending video to hosting location and receiving audio/video through standard web traffic (80 & 443) or return traffic is coming in over already open ports (highly unlikely).
