Call flow troubleshooting

PortSIP has been building its SIP Trace Server base on the open-source project HOMER, which provides key information in troubleshooting SIP Trunks, SIP endpoints, and other SIP related issues. It provides a place to:

Access singularly to retrieve SIP captures via Web UI
Centrally store SIP capture data across many hosts
More intuitively filter SIP capture data and correlate the data to the dialog/transactions each request/response is part of (immensely useful!)
Gracefully age dated capture data you don’t want to persist for very long (though persisting longer term can be configured very easily)
Charts! glorious charts!
