You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: api_op_GetSipMediaApplication.go
    path of file: ./repos/aws-sdk-go-v2/service/chime
    
    the code of the file until where you have to start completion: // Code generated by smithy-go-codegen DO NOT EDIT.

// Retrieves the information for a SIP media application, including name, AWS
// Region, and endpoints. This API is is no longer supported and will not be
// updated. We recommend using the latest version, GetSipMediaApplication (https://docs.aws.amazon.com/chime-sdk/latest/APIReference/API_voice-chime_GetSipMediaApplication.html)
// , in the Amazon Chime SDK. Using the latest version requires migrating to a
// dedicated namespace. For more information, refer to Migrating from the Amazon
// Chime namespace (https://docs.aws.amazon.com/chime-sdk/latest/dg/migrate-from-chm-namespace.html)
// in the Amazon Chime SDK Developer Guide.

// Deprecated: Replaced by GetSipMediaApplication in the Amazon Chime SDK Voice
