I have a situation that I can't get my head around. Every so often I have a SCA seized
and I need to manually release it. Here is the log of the sca and bye from the event
logs.

I am running Kamailio 4.2.6. The phones are Polycom VVX 310/410 running 5.3.1. And the
PSTN gateway is an Audiocodes Mediant 1000 running 6.60A.292.001.
The call volume is light so I don't think there is a lot of traffic but there is about
16 phones one SCA. It is not happening all time. Could be a couple days that nothing
happens and then there could be a couple days that it happens multiple times a day. I
can't find a common element that would be causing this unless the 'bye' is
closing the call before the SCA has a chance to do something with it.
Thanks

If you can get a clean packet capture, feel free to send it to me off-list.
If you can't, then perhaps you can dig all of the Kamailio logs out for
those call IDs?

It will be hard to get a packet capture but I can give you what I have in the logs. I will
also get homer going which should give us a better capture due to it sporadicness.
Where would you like me to send it too?

What is the email address to send you the capture and SCA output. I think I see the issue
but don't know why it happens?

Jorj,
The issue seems to be only with the Polycom UA making a call outbound. I can not find an
issue with and inbound call. The Call-ID of the seize/appearance seems to be missing some
characters on the prefix of the at-sign in relations to the real Call-ID of the
INVITE/BYE.
Just my observation.

Apologies for being unresponsive; I've recently left Penn.
I'll need more detail, unfortunately. Can you send any log messages
relating to that Call ID?

I do not have that log file any more. I will need to look for a new seize and give you
that info.

Jorj,
It happened again but the logs do not show any reference to the Call-ID except the
<BYE>. I can not find the invite for that call in the logs.
I have a Homer capture of the <INVITE> to the <BYE>.
I'm going to see on my test system if I can find out why we might be missing these
<INVITE>s.

Yes, it is still happening under 4.2 at the current git patch.
Phones are Polycom VVX310/410 at 5.3.2 and I have Homer running to capture.
Problem is only outbound from Polycom to an outside line via an Audiocode Mediant 1000
with the phone(s) having 2 different SCA's and 2 to 3 line appearances per SCA.

@JorjBauer used to maintain the module at some point, but I think he changed positions and
not sure if he is still involved in some work with the module.

Good day.
I think I have a lead on this to help come up with a resolution. I might be able to do it
myself but I need to really dig into the code and kamailio to understand it better.
First, I was using the sip_trace module along with Homer to gather the info, but it did
seem incomplete. The work of the SCA module is not picked up by the sip_trace module. I
believe because it if doing instead script work and sending its own packets, which would
not be picked up by the script anymore. I finally used sngrep (referred by Javan Strika
who is also having the issue) and was able to see the entire conversations for the
SCA's. But the sngrep in a "HEP" and "non verbose" mode seems to
have a memory leak and will crash kamailio due to no more memory. So, I am now turning to
captagent to get a more stable system to get better traces for this issue.
Now for the SCA problem. It seems that the unreleased "seized event" resides
with the "held" event and the reinvite/invite that occurs to kamailio. It seems
to get lost, hungup. pushed around or jacked up in the 'route[WITHINDLG]' section
of the script and the reinvites/invites will keep happening until a timeout occurs or the
sometimes I have seen the 404 Not here error occur.
I know this is not much to go on until I upload a good trace but maybe a brainiac might
go...Oh, I know that problem and quicker fix.
Using Kamailio 4.2.7 with latest patches. CentOS 6.7-latest. One test bed is a mix of 2
Polycom VVX [34]10 with 5.4.4 and 1 Polycom 650 with 3.3.5; Another is a mix of 14
Polycoms VVX [34]10 with 5.3.2, another is a mix of 4 Polycom VVX [34]10 with 5.3.2
