What should I look for in a SIP trunking provider? 

At a minimum, a quality SIP trunking provider should provide access to local numbers via Tier-1 carrier networks and have negotiated connections with carriers in the regions where you operate. The provider must have multiple carrier connections and redundant infrastructure to ensure service reliability. Other key factors include pricing, instant provisioning, interoperability support, and security. 

 

How do Plivo’s voice geo permissions work? 

Geo-permissions help protect Plivo users against telecom fraud by restricting the countries that can be called from an account. Use the Voice Geo Preferences page in the Console to see your default list of disabled countries and enable or disable outbound calls to specific countries. Once these settings are saved, they’re immediately applied to all calls placed via Rest APIs and Dial XML. 

 

Why is Plivo requiring us to upgrade to TLS 1.2? 

Starting January 12, 2021, Plivo will support only TLS 1.2 and above. TLS 1.2 is a more secure version of the protocol, and we recommend that you move your applications to TLS 1.2 immediately. This upgrade will ensure that Plivo is less vulnerable to potential security breaches, and that your data is protected. With TLS 1.2 enabled, you will be less vulnerable to cyber attacks. 

 

What is two-factor authentication (2FA)? 

Two-factor authentication, or 2FA, protects organizations and individuals from unauthorized data access by requiring an additional level of authentication to ensure that a password has not been compromised. Plivo offers a reliable, scalable phone number authentication solution in a single API for SMS or Voice one-time password authentication. 

Why is a Sender ID registration important? 

A Sender ID indicates who is the sender of SMS and MMS messages in all countries except the US and Canada. Marketing teams love Sender ID because it enables them to set their brand name as the Sender ID for better brand recognition and engagement. In some countries, the Sender ID displayed to a message recipient can display a custom alphanumeric phrase such as the company’s name or service. (387/400)

 

Why is phone number validation important? 

Phone number validation determines number format, type, country, and carrier for any phone number worldwide. This detailed information minimizes delivery errors, increases conversion rates by segregating landline from mobile numbers, and reduces risk by comparing the IP location with the phone number’s country. 

 

What is the character limit for SMS messages? 

Plivo supports two of the main types of character encoding: GSM and Unicode. GSM limits individual messages to 160 characters, after which Plivo will split the content into multiple messages, with a maximum total of 1,600 characters. Messages sent using Unicode have a maximum length of 70 characters, after which d Plivo will split the content into multiple messages, with a maximum total of 737 characters. Each message will be charged individually.

 

What is A2P 10DLC? 

A2P 10DLC text messaging allows application-to-person (A2P) SMS traffic over long-code phone numbers. Verizon was the first carrier to launch and AT&T has followed suit. The carriers now require SMS providers to 1) register their business and 2) register each use case as an individual campaign. All transactional and promotional use cases, must be registered, irrespective of volume.
