An Avaya OneCloud CPaaS-enabled user can send SMS through Presence Services REST APIs.
The user or application can use Avaya OneCloud CPaaS address space to specify the recipient mobile number.
ADDITIONAL INFORMATION:
There is no need to suffix the number with zang.io domain.
If the mobile user sends an SMS or replies to an SMS, the SMS is delivered to the Aura user as an IM through the Event Delivery Service on Avaya Breeze® platform.
