-{{description>​termmaxdigits VoiceXML property | termmaxdigits sets the numbers of DTMF input digits to be collected, with immediate timeout when reached.}} 
-===== termmaxdigits ===== 
-**Default Value:** false 
-Enables the behavior "​termchar Empty When Grammar Must Terminate"​ described in [[http://​​TR/​voicexml20/#​dmlATiming|VoiceXML 2.0 Specification - Appendix D]]. An immediate timeout on dtmf collection for grammars builtin:​digits (with length or maxlength set) or builtin:​boolean grammars. If any other grammars are active during recognition this behavior is disabled.

-From this example, by setting "​termmaxdigits"​ to true, we can allow for no timeout as soon as the user has matched the maximum number of digits. If the user enters 5 numbers, the behavior of the application immediately returns a response to the user. If the user entered less than 5 numbers of ones or twos, the application waits for 3 seconds from the "​interdigittimeout"​ property and returns a <​nomatch>​ after 3 seconds has passed with nothing inputted. If the user entered more than 5 numbers, the application returns just the first 5 digits that were entered by the user.
