Feature-Request: Support for multiple X-Call-ID headers

[zombiedk]

if you have a call that is stretching overs several dialogs (A,B,C), it would be nice if the "F4 Extended" dialog support multiple X-Call-ID headers
currently it will only match on the first header, and depending on how I add them I can either make that dialog A will show B+C but dialog B will not be able to show C
or if I reverse the order of the header A will only show B and B will only show C

[zombiedk]

at the moment we bypass the limit by finding the first call and and then do a search for that Call-ID
thereby get a list with all the dialogs that have that string

Hi!

If I understand this correctly, the problem is that Exended Flow from A call works as expected displaying B and C, but Extended Flow from B (or C) call only shows A call.

Is this correct?

[zombiedk]

yes that is correct

senario 1
dialog A: Call-ID=AAA
dialog B: Call-ID=BBB , X-Call-ID=AAA
dialog C: Call-ID=CCC, X-Call-ID=AAA, X-Call-ID=BBB
F4 on dialog A you will see all 3 dialog
F4 on dialog B you will not show dialog C

senario 2 reverse order of X-Call-ID header
dialog A: Call-ID=AAA
dialog B: Call-ID=BBB , X-Call-ID=AAA
dialog C: Call-ID=CCC, X-Call-ID=BBB, X-Call-ID=CCC
F4 on dialog A will only show dialog B
F4 on dialog B will show dialog C

I have attached 2 pcap that show the 2 different senarios

alternativ add support for Session-ID (rfc7329) as an alternativ to X-Call-ID
Session-ID is a globally unique session identifier

[sergey-safarov]

agreed, more correct to support Session-ID according to RFC.
