1) Is this method per user?
2) Another thing is, what happens if the BYE is not received (network
issue or whatever), will the dialog expire on the kamailio side so the
dialog count could me decremented? I mean, if the user has just 1
voice channel, he could not make a call anymore, that's why it should
be reliable..
if it's acceptable for you to use an external B2BUA, you could
send
the calls through SEMS' sbc, activating session timers there and using
parallel calls cc_pcalls to limit.
e.g.
sems.conf:
load_plugins=sbc;session_timer
sbc.conf:
profiles=limit_calls_sst
active_profile=limit_calls_sst
limit_calls_sst.sbcprofile.conf:
call_control=parallel_calls
parallel_calls_module=cc_pcalls
parallel_calls_uuid=$fU
parallel_calls_max_calls=1
# enable session timers - will refresh
# even if endpoint doesnt support it
enable_session_timer=yes
# refresh every minute
session_expires=120
or, if you want to control it through some header:
limit_calls_sst.sbcprofile.conf:
call_control=parallel_calls
parallel_calls_module=cc_pcalls
parallel_calls_uuid=$H(P-Parallel-Calls-User)
parallel_calls_max_calls=$H(P-Parallel-Calls-Max-Calls)
header_filter=blacklist
header_list=P-Parallel-Calls-User,P-Parallel-Calls-Max-Calls

I was using cdrtool (prepaid table) and callcontrol to limit
concurrent calls. In fact this is only limiting the outbound
calls,
but I would like to use another mechanism which should limit the
inbound calls too. So basically to limit voice channels.
So is there some reliable method/module how to achieve this?
The 'dialog' module is a common approach to this problem.
Organise both inbound and outbound dialogs into profiles, and
then get_profile_size() in both your inbound and outbound call
processing.
