Naveen have you tried a "true" tandem call, I mean one that has no user
intervention, so an incoming gateway call then just routes straight back out
on another Gateway as per the dial plan?

Yes, please raise a Jira issue for this.  Conference, ACD calls and Paging
from an internal user should be classified as Internal.  There may be a flaw
in how the Call Direction is being calculated by the Reporting or it may be
a flaw in the CDR record.

 

BTW.  There is another category of call that can be reported in the Call
Direction report.  The type is "Tandem" and occurs when an external incoming
call is "passing through" the system.  Also note, that categories which have
no calls will not be shown in the report.  For example, if no Internal calls
were made during the time period of the report, the Internal category will
not be shown.

Hi Raymond ,

Thank you for the reply . I raised Jira issue XX-6384
<http://track.sipfoundry.org/browse/XX-6384>  for above the scenarios (ACD ,
Paging & Conference calls).

Today I tried hairpin transfer scenario to find out the 4th category
"Tandem" . Steps followed as below ,

1.Dialed 384 (SCS user) from PSTN phone (08041315953)
2.Answer the call from SCS user (384) , and from 384 do a blind transfer to
another PSTN number (9845186164).
3.PSNT phone (9845186164) starts ringing and 384 got disconnected.
4.Answer the call from PSTN phone (9845186164) , now call established
between two PSTN phones .
5.Hangup the call.

After this navigated to Call Direction page , but not found "Tandem"
category . Transfered call is listed under "Incoming calls" and completed
calls are listed under "Outgoing calls" (screenshot attached - tandem1.png &
tandem2.png).

Categories which have no calls are not shown in the report , and works as
expected. When there is no calls in any of the category a null table
displayed (I think this also works as expected - attached screenshot -
null.png).

Please advise whether to raise a Jira issue for this also .

Thank you ,
Naveen
