December 2020 Summaries

Primary Rate Interface (PRI) and Session Initiated Protocol (SIP) are two technologies used for telecommunications. PRI is an older, wired technology that uses physical circuits to transmit calls, messages, and data. It supports up to 23 concurrent communication channels. SIP, on the other hand, is a wireless technology that uses the internet rather than a physical connection. Both technologies can provide solid call quality, but businesses are increasingly ditching PRI for SIP due to its advantages in availability, scalability, cost, and access to new technologies.

Text message link tracking is a critical tool for measuring ROI, but it can lead to poor user experiences and blocked messages due to the use of public shortened URLs, which often redirect multiple times and obscure sender identity. To address these issues, T-Mobile's Code of Conduct for business messaging, effective from September 1, 2020, advises using recognizable and singular domain names for messaging programs to enhance brand continuity and consumer confidence, while banning practices like URL cycling and multiple redirects due to their association with fraud. AT&T has already blocked public link shorteners outright. Businesses are encouraged to use full-length URLs or branded short URLs to improve deliverability and avoid message filtering, with the ultimate goal of reducing spam and fraud within the industry.
