    International Telephone Input

    International Telephone Input

    Plugin for entering and validating international telephone numbers

    A JavaScript plugin for entering and validating international telephone numbers. It adds a flag dropdown to any input, detects the user's country, displays a relevant placeholder and provides formatting/validation methods. Lots of initialization options for customization, as well as public methods for interaction. The user types their national number and the plugin gives you the full standardized international number. Navigate the country dropdown by typing a country's name, or using up/down keys. Automatically set the input placeholder to an example number for the selected country. Automatically select the user's current country using an IP lookup. Access the country data to create a separate country dropdown for an address form, and then listen for change events to keep the two dropdowns in sync. Use Twilio's API to build phone verification, SMS 2FA, appointment reminders, marketing notifications and so much more.

    sippet

    sippet

    C++ SIP stack based on Chrome source code

    This C++ library has been designed as a Chrome SIP stack. Sippet is an open-source SIP User-Agent library, compliant with the IETF RFC 3261 specification. It can be used as a building block for SIP client software for uses such as VoIP, IM, and many other real-time and P2P communication services. The main target was to enable Javascript applications to use UDP, TCP and TLS transports along WebSocket. Existing SIP solutions for the browser are forced to use the WebSockets API to send/receive SIP messages. But for many service providers, the WebSocket protocol could not be a feasible solution due to scalability, support and other business constraints. By the way, the stack can be used as a full client-side C++ Stack (full-featured) without Javascript integration.
