Providing real-time billing to your communication platform as a service (CPaaS) customers is critical, as it ensures that everyone pumps traffic within the authorized limits. Centralized and real-time charging expands your selling possibilities and decreased your risk of fraud by a significant percentage.

In this blog post, we’ll go over how to use TelecomsXChange (TCXC) as a realtime Authentication, Authorization, Accounting (AAA or Triple A) for your Restcomm cloud CPaaS platform.

TCXC can provide your sub-accounts on Restcomm cloud with realtime prepaid charging leveraging Restcomm Bring Your Own Carrier (BYOC) feature. This feature allows you to route each sub-account to a a specific SIP or SMPP profile.

Let’s say you want sub-account AC12348xxxx for (Enterprise A) to go through prepaid billing before the message or voice call is finally sent out, in a few steps you’re able to achieve this:

• Login to TCXC Buyer Portal
• Link your TCXC Account(s) with your Restcomm Sub-account(s)
• Manage prices for Voice and SMS in TCXC Seller console or API
• Set prepaid limits or credit limit per account, when account reaches 0 the traffic will be automatically blocked.
• SMS / Voice Traffic will pass through TCXC to perform AAA before it’s sent to the final termination destination

A critical part of CPaaS is phone numbers (AKA Virtual Numbers or DIDs), TCXC platform gets this part handled, sellers can host and set the pricing for phone numbers using the TCXC Seller console or API,

• Set per message incoming rate for SMS (Concatenated Billing is supported)
• Immediate wallet deduction upon purchase
• Low balance reminders
• Upcoming number renewal alerts
