Make calls searchable by duration #642

I'd like to make a feature request to search for calls based on duration or relative times. For example:

Any answered calls from source 1.2.3.4 shorter than 15 seconds
Any calls where a CANCEL was received in the first 5 seconds
Any calls where the difference between the initial INVITE and the first 200 OK is more than 60 seconds etc

Basically mostly things you usually record in CDRs (ringing time and call duration) but without the extra step of searching cdrs -> extracting callid -> searching in homer.

Hi @fredrik-dahlgren If you have CDRs expressing this already, the best way is to ingest them in HOMER with a Mapping and use them for searching - the SIP correlation would be automatic and so would the correlation.

I actually don't save the ringing time in CDRs and i'd prefer not to duplicate (quite a lot of) data into homer if possible. But in any case, where can i find the documentation for correlating CDRs in Homer? I've added a correlation for X-CID according to this: https://github.com/sipcapture/homer/wiki/Custom-Header-Searching-and-Correlation but i'm not sure how to add and correlate other sources.
