<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">So, I'm not sure this is the behaviour that we would want.
If a channel driver provides presence information, then the presence information provided by the channel driver supercedes any custom presence provider. That is:
exten => hint,SIP/alice&CustomPresence:alice
Will *always* use the presence provided by SIP/alice, instead of the custom presence provider. That feels like a loss of functionality.
Prior to this patch, we would only use the presence information provided by a single custom presence provider, since presence information could only come from custom presence providers. If the channel drivers provide that as well, there probably needs to be some mechanism to aggregate that together.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Supporting multiple providers would be better. It turned out this wasn't just a matter of putting a strsep() loop in ast_presence_state_helper().
This hint parsing code in presence_state_cb (main/pbx.c) only supported a single provider, so I had to modify add_hintdevice() to include the presence hints and then rewrote the lookup code based on that in device_state_cb().
The overall presence state is whichever provider is most-unavailable, eg: if SIP/alice is DND and CustomPresence:alice is CHAT then the presence state is DND.</pre>
