Abstract
A user is presented with a list of languages sent by an interactive response system in a Session Initiation Protocol (SIP) communication session. For example, the user is presented with a list of languages supported by an Interactive Voice Response system. The interactive response system receives a selection of a language from the list of languages supported by the interactive response system from the user. The SIP communication session with the user is sent (e.g., forwarded) to another communication device by sending a first SIP message, such as a SIP INVITE message. The first SIP message includes a SIP History-Info header that identifies the selected language for the first SIP communication session. The selected language can then be used to forego presenting a list of languages to the user later on during the SIP communication session.
