Hi Team

Kindly suggest, if we can record the Avaya One-X mobile user calls via DMCC Multiple Registration method.

Thanks

Yes, according to the DMCC Programmers Guide (.Net version):

Cell phone recording
AE Services 6.2 introduced the ability to record calls originating or terminating at
a cell phone. This feature combines the AE Services Multiple Registrations
method with the Avaya EC500 or the Avaya One-X Mobile (OPTIM) applications.
The DMCC service client application is able to connect to, and record, calls:
o answered either at the desk set or at the mobile device
o answered at the desk set and then extended to the mobile device
o answered at the mobile device and then retrieved at the desk set
