Hi all Using asterisk 16.25 I was trying to stop Mixmonitor using features. The code is executed but I realized that I was executing StopMixmonitor from another channel so I opted to use AMI. When I call MixMonitor I store the channel name in a var and then I use StopMixmonitor from AMI sending the stored channel name as parameter. What I've seen is that the app returns failure and going a little bit deeper I see that the failure comes from the function stop_mixmonitor_full in app_mixmonitor.c datastore = ast_channel_datastore_find(chan, &mixmonitor_ds_info, S_OR(args.mixmonid, NULL)); if (!datastore) { ... return -1 I know the error comes from that !datastore but I do not know how to follow and dig into the problem. any help? cheers, Jon -- PekePBX, the multitenant PBX solution https://pekepbx.com
