Hi,
we are integrating Nuance Speech Server with Cisco CVP.
In form element settings we are pointing voice grammer URI and for DTMF Keypress we mentioned as [0123456789#]+
Currently i am using the Voice Gateway Cisco Unified CVP4.1/7.0/8.0/8.5 VoiceXML2.1 with OSR3/Nuance9
if the user will enter any number say for example 999 every time CVP server will return no match and it is not identifying the user entered DTMF input.(Thre is no issue for Voice Input).
For DTMF Keypress 1 ,DTMF Keypress 2 in these two cases are working but regular expression is not working in my production setup.
please give me some suggestions to capture either voice or DTMF inputs.
Regards
Juluri.

The following is true, if you have Nuance. You can enter any of these into the Voice Grammar setting of the form element. builtin:grammar/digits builtin:grammar/digits?length=5 builtin:grammar/digits?minlength=5 builtin:grammar/digits?maxlength=8 If you want to collect only 5 digits or 7 digits, and nothing else, you list both, on separate Voice Grammar lines: builtin:grammar/digits?length=5 builtin:grammar/digits?length=7 And this is the format for the DTMF Grammar setting (if you are using Nuance to collect them): builtin:dtmf/digits builtin:dtmf/digits?length=5 builtin:dtmf/digits?minlength=5 builtin:dtmf/digits?maxlength=8 Similarly, if you want to collect only 5 digits or 7 DTMF digits, you list both, on separate DTMF Grammar lines: builtin:dtmf/digits?length=5 builtin:dtmf/digits?length=7 If you want to collect the # then you have to disable its use as the termchar by setting the VoiceXML Property Name:termchar Valueenter one space key) you can do this in the Settings tab of the Form element. And then you also have to specify that # is a valid entry in the Form. You can do this using the DTMF Keypress setting in addition to the above: DTMF Keypress: # If you want to collect the * key, then you can add another DTMF Keypress setting (right-click) and enter DTMF Keypress: * When using Nuance, you do NOT use the backslash before the *, that's only for DTMF-Gateway Janine

Hi Janine,
I tried your approach and it is working fine.
Thanks for your support and valuable suggestions to me.

Juluri.

Yes, I have similar results. Try this one and see if it works: (assuming you want only 5 digits). If not change the min length to whatever you want the min to be.
builtin:grammar/digits?minlength=5 builtin:grammar/digits?maxlength=5

Subject: New Message from subrahmanyam juluru in Customer Voice Portal (CVP) - General Discussion - All Versions: RE: Re: New Message from subrahmanyam juluru in Customer Voice Portal (CVP)

subrahmanyam juluru has created a new message in the forum "General Discussion - All Versions": -------------------------------------------------------------- Hi Janinee,

I used the following builtin DTMF Grammer settings in my application.

builtin:dtmf/digits
builtin:dtmf/digits?length=5

The basic functionality is working fine ( Accepting the DTMF input ) but the validation will be failed.
if the user entered more than 5 digits the system will accept the DTMF Input.
Please suggest me why it accept more than 5 digits ?
I need to do changes in the call studio Script.
I am sharing some logs to you. Please verify following logs.
