Outbound Call Duration Issue

[kofaisal94]

I'm facing an issue with some manual outbound calls, I am getting either 0 seconds in length_in_sec field at table vicidial_log or a length_in_sec value that is extremely higher than the real call duration
im further investigated the issue and found that for those erroneous records, the start_epoch and end_epoch values are the same.

any help, please
