We are looking at using call data for generating certain Custom Reports combined with data from our CRM. We have option to look at ASMS data or ECHI ( External Call History Interface in CMS) data for call data. We may in future look at email/web chat related reports as well.

Are there any advantages of using one over other option?

I have a specific question is around Segment data. Are call segment timestamps in ASMS same as ECHI data?

Thank you
