update hupall API to support multiple variables
hupall [cause] [[var1] [val1]] [[var2] [val2]] ...
added switch_core_session_hupall_matching_vars_ans() which will hang up all channels that match each variable(s) value
This change implements a few new features, there's no behavior change at all.
1 - BLF for queues
You can now use BLF for knowing when there are callers waiting on a queue,
the pattern to be subscribed is callcenter+queuename@default or @domain name.
2 - callcenter_track app
Now every agent has an external_calls_count column that will be read upon
selecting agent to offer new calls.
If you start an external call (inbound or outbound) and don't wan't
mod_callcenter to offer new calls for this agent just call this app
passing the agent name as argument:
<action application="callcenter_track" data="agent1"/>
This will increment the external calls count, and to make mod_callcenter look to this variable you need to set this queue parameter:
<param name="skip-agents-with-external-calls" value="true"/>
3 - EXIT_WITH_KEY reason
If the member press a key to exit the queue the cc_cancel_reason will be this now.
4 - xml_curl config loading improvements
Prior to this mod_callcenter query your web server a LOT of times,
this will make it only query once per queue, just watch for CC-Queue
request param and build your xml with everything related to that queue,
including tiers (tiers wasn't loaded before this).
Addition of detectors which skip first few frames
of audio before they start to process it helps
to properly handle some Verizon voicemails.
The result of avmd test using this commit is
OK. All PASS [100]
Thi scommit also resolves:
FS-9588 Add script for outbound avmdy
FS-9589 Add resolution info to events
Now avmd detection is done in detector threads
processing audio frames with different resolution
and/or offsets. Detection decision is based on relative
standard deviation which dynamically adjusts to the signal.
Detection of amplitude, frequency and both simultaneously
is enabled and corresponding setting added to the configuration.
Frequency estimates are filtered with median filter.
This commit also resolves:
FS-9539 - Get estimates with different resolution
FS-9513 - Use adjustable thresholds
FS-9502 - Add detection mode setting
FS-9501 - Enable three modes of detection
FS-9407 - Add check of amplitude for NaN before appending to SMA buffer
FS-9139 - Unit test framework
