Proxy Public Beta is currently closed for new customers. Please consider using Twilio Conversations and Programmable Voice directly if you are building your masking application.
Note that this does not have any impact on Twilio Flex customers.
Twilio's Proxy API is currently available as a Public Beta product. Some features are not yet implemented and others may be changed before the product is declared as Generally Available.
Public Beta products are not covered by a Twilio SLA.
It often happens that Proxy receives messages and calls to Proxy numbers in your numbers pool that are not from a Participant in an Open Session. When that happens, if your Proxy Service has an Out of Session Callback Url specified, Proxy will forward that inbound payload to you, along with any information we may have as to previous Sessions for the caller/sender.
There are two types of responses you can return to customize your customer's experience:
Content-Type response header set to application/xmlContent-Type response header set to application/jsonThe ability to return TwiML for Programmable Voice and TwiML for Programmable SMS allows you to customize the out-of-session caller/sender experience by enabling you to respond with custom <Play>, <Say>, <Message> and other verbs.
If you determine, based on the information included in the callback payload, that the caller/sender should be connected to a particular Agent (Agent X), you can respond with json that tells Proxy to create a Session between the caller/sender and Agent X. Proxy will create the Session and Participants and will then proceed as if the caller/sender had reached an open Session.
