Situation: VoIP ISP server suddenly became unavailable and you have some thousands of dialogs like this:
dialog:: ID=17580696317398
state:: 3
user_flags:: 0
timestart:: 1556697836
datestart:: 2019-05-01 13:03:56
timeout:: 1556701436
dateout:: 2019-05-01 14:03:56
callid:: 7EB7F3F9-6B1E11E9-90F3C2ED-81742C80@XX.YY.168.28
from_uri:: sip:ZZZXXX7146@XX.YY.168.28
to_uri:: sip:NNNN902290@XX.YY.169.130
caller_tag:: 8999291C-450
caller_contact:: sip:ZZZXXX7146@XX.YY.168.28:5060
callee_cseq:: 0
caller_route_set:: <sip:XX.YY.169.130;lr=on;ftag=8999291C-450;did=dff3.a92b;nat=yes>
caller_bind_addr:: udp:EE.FF.116.74:5060
caller_sdp::
CALLEES::
callee::
callee_tag:: as3d7dee61
callee_contact:: sip:abc@EE.FF.116.62:5060;transport=udp
caller_cseq:: 101
callee_route_set::
callee_bind_addr:: udp:EE.FF.116.74:5060
callee_sdp::
To kill them in some seconds (not to wait when OpenSIPS will terminate them according to SIP timers), do:
for i in `opensipsctl fifo dlg_list | grep callid | grep \@XX.YY.168.28 | awk '{print $2}'` ; do opensipsctl fifo dlg_end_dlg $i ; done
In fact, the situation was as follows: VoIP software on the ISP side (we have a DID from it connected to our OpenSIPS cluster) had some problems and they suddenly started sending us a bunch of unique INVITES (with different Call-IDs) for any certain inbound call.
Very soon the total number of dialogs dramatically increased up to enormous values. And this is a theme of my next article!
