Hi There, I Can Help You with the required App development. As you know that SIP Channel Module enables Asterisk to communicate via VoIP with SIP telephones and exchanges. Asterisk can act as A SIP client: Incoming calls are routed to an Asterisk extension. A SIP server: Asterisk can be configured so that SIP clients (phones, software clients) register to the Asterisk server and set up SIP sessions with the server, i.e. calls and answers incoming calls. If you are going to have thousands of SIP phones, you should use SER or OpenSER and forward calls to Asterisk for voicemail or PSTN access. A SIP gateway: Asterisk acts as a Media Gateways between SIP, IAX, MGCP, H.323 and PSTN connections. As an example, an Asterisk server can be connected to ISDN to give your SIP clients connectivity to the switched telephony network. These are some of the aspects, there are many other aspects which are beneficial for your site. We can discuss it over Chat or Voice Call. You can also have an interview there. I am having 8+ years of experience, I am mentioning below some of my exclusive expertise for you: Backend: PHP, Node.js, Python, Mobile app development: Flutter, React Native, Native IOS/Android Design and Enhancement: Twitterbootsrap, Ajax, Javascript, HTML, CSS, Jquery, MAC, MAYA Database: MySQL, Postgres, SQLite, MongoDB Clouds: Heroku, Amazon, Linode, Rackspace. API: Twitter, Linkedin, Facebook, Google, Yahoo Thanks! Sufiyan R
