Hi Alex,
Thank you again for looking at this.
I am including a snippet of the last part of the Wireshark dump that occurs right before
the dropped call. There are many of the very same INFO Request going from Asterisk to
Kamailio; there is also another INFO request in the middle that was different (but only
occurs a few times). The INFO Requests do have ;tag in the To header.
I noticed that Asterisk replies '200 OK' to INFO request from Kamailio but
Kamailio does not send '200 OK' for INFO requests from Asterisk. I did try
forcing Kamailio to send a '200 OK' when it gets an INFO request, but that did not
work.
You will see that there are a bunch of INFO request to Kamailio from Asterisk, then
Kamailio sends a 408 Request Timeout , then Asterisk send a BYE and call drops shortly
after.
Thank you!!,
-Steve

Hi Alex Thank you!, there is so much to learn.
As you suggested, I looked at the CSeq and the Timeout is from an INFO
message going from Kamailio to Asterisk. Asterisk immediately sends
"BYE" back to Kamailio and then the call drops. This is why I was
wondering if I needed to do anything for INFO messages. "I think"
this is why some calls are dropping. Does this make any since?
It does. Is the INFO message in-dialog[1] or out-of-dialog?
[1] Does it have a ;tag attribute in the To header?
