We have helped several clients to create applications to handle both incoming and outgoing message. We help companies to design great IVR solutions that access backend databases to make decisions during incoming phone calls. We are familiar and have experience with all of the following Twilio APIs.

• Twilio REST API – We have extensive experience with the core Twilio API. Send messages, make phone calls, and access Twilio account data.
• Twilio Numbers Lookup REST API – Look up number type (mobile versus landline), carrier, and other information for individual phone numbers with this REST API.
• TwiML – XML markup language, which you use to tell Twilio how to handle incoming voice calls or SMS/MMS messages.
