I have using wireshark to get the TCAP message, it is very easy to install and use it is a opensource tool to capture the TCAP message generated during calls. The interface is also good. Review collected by and hosted on G2.com.
The tool is very useful but sometimes a new user can stuck since their are various options but overall it is a very useful tool and I don't think their is anything which I dislike about this particular tool. Review collected by and hosted on G2.com.
