You should never compare ao2_link with an explicit value.  ao2_link used to return a pointer so you could not know what value it would return.

You should treat the return value as a boolean and compare it like this.
if (ao2_link())
or
if (!ao2_link())

> ARI music on hold for bridges works by creating a dedicated announcer channel for playing music on hold and putting it in the bridge. This channel will play music on hold until it is removed from the bridge at which point it will hang up. Issuing a new music on hold command with one running will fetch that channel and issue a new music on hold command which will do nothing if it uses the same class or will start playing the new class if the music on hold command specifies a class other than the one provided. If the moh stop command is issued and an MOH channel exists for that bridge, it will be hung up.
