SMS Registration

SMS RegistrationSince the beginning of February 2021, the major wireless carriers (Verizon, AT&T, and T-Mobile) have been working with The Campaign Registry (TCR) to implement a process to register everyone using VoIP and US local phone numbers to send SMS or MMS messages. All US local (NANP) VoIP SMS numbers must be registered with the TCR, this includes low-volume customers/numbers. A couple of reasons for the TCR and campaign registration: (1) it protects the end-user from spam (2) and it keeps further FCC requirements and regulations from being implemented.

What is Split DNS and how do I implement it in 3CX V20

What is Split DNS and how do I implement it in 3CX V20Split DNS is a network configuration technique that allows a domain name to resolve to different IP addresses based on the origin of the request - internal network or external internet. This is particularly beneficial for organizations looking to manage traffic efficiently for VoIP systems like 3CX. The move to using FQDNs over internal IP addresses in systems like 3CX V20 is driven by the need for enhanced security, simplified configuration, better NAT compatibility, and easier certificate management. Implementing Split DNS in 3CX V20 involves configuring DNS settings to ensure FQDNs resolve to the internal 3CX server's IP address for internal requests while Cloudflare's API manages external requests. The upgrade to version 20 signifies a significant shift towards using FQDNs for system-wide communication, enhancing security and network efficiency.

How Close Are We to Telecom as a Service?

How Close Are We to Telecom as a Service?In part 1 of this article, we started investigating the idea of telecom as a service.
