You can look at the network traffic using tools such as ngrep, sipgrep, tcpdump or wireshark.

An example with ngrep for sip udp on port 5060:

ngrep -d any -qt -W byline port 5060

I am not the developer of sipcapture module, but from the parser errors it seems that it tries to parse an empty string.

The database errors are related to a duplicated value on an unique key column.

Maybe Alexandr (author of sipcapture) can comment more on the logs.

Cheers,
Daniel

I turned on debug=3 and the messages change a bit (listed both below)
Look into how to check database and traffic..sorry, not super strong on that side.

Thanks again for thoughts.

Hello,

are this errors in the node saving to the database? Can you look at the network traffic and see what is received there?

Also, you can try to run kamailio with debug=3 in kamailio.cfg -- that will print a lot of debug messages that can help troubleshooting.

Cheers,
Daniel

Hello, I finally got everything working but see to consistently receive the following 3 errors (see below) over and over when a call is being collected?
Versions:

Any assistance would be appreciated.
Thanks, Jeff
