Displaying OH323 calls

This node is meant as a handy guide to showing ongoing OH323 calls in your Asterisk system.

To make full use of this tutorial, you first have to start the Asterisk CLI, with a command like:

asterisk -vvvvvvvvvvvvvvvvvvr

It will attach itself to the local Asterisk instance.

The basic OH323 monitoring commands are all under oh323 show …

oh323 show estabilished

This is the basic command showing how may active connections are present in the system. Nothing to be too excited about. :-) the first line in the example is the line you enter.

ast*CLI> oh323 show established
2 established H.323 connection(s)

oh323 show info

This command exposes the details of the ongoing connections. Note how you can see the codec and the call state. (Note that from oh323 v0.6.5 onwards, the command is called oh323 show channels ).

ast*CLI> oh323 show info
Information about active OpenH323 channel(s)

oh323 show vars

This command shows the gory details of each call, as seen by the channel variables that can be accessed by the Asterisk dial plan. Note howw you can therefore get the caller id and the used codec.

ast*CLI> oh323 show vars
