Setting up video calls

To allow our IP-PBX to display a video during a call, we must add the default codecs for video support and configure the extensions to support video. In this section, we will show the steps for enabling video calls.

How to do it…

To add video support to our Elastix box, we must edit the file sip_general_custom.conf in the PBX | Tools | Asterisk File Editor menu by adding the following information:
```
videosupport=yes
maxcallbitrate=384
allow=h261
allow=h263
allow=h263p
allow=h264
```
Add the video codec declarative in the extension configuration options by using the PBX | PBX Configuration | Extensions menu. This step is shown in the next screenshot:
Finally, we can call another extension with video support as shown in the next image.
Tip
There are some softphones and telephone sets that can support three-party video conferencing. This depends on each model and brand hardware specification. To learn more about codecs, please visit: https://wiki.asterisk.org/wiki/display/AST/Codec...
