DialogFlow: Better understanding of phone number

We are try'ng to input phone number in an Intent in DialogFlow via voice

But we have big problems with voice interaction even with different people (let me say with a good and natural English)

Using type sys.phone-number we obtain weird result as for example Original Number as reported on DialogFlow Interface 3 8 3 3 5 7 7 6 6 4 4 4 Result number in web hook 3 8 3 3 5 7 7 6 6 4 4 (missing last number)

Another example sometimes we use double7 to indicate 77 , and the double is total missing we obtain only one 7

Same behaviour with sys any sometimes apppear a 0 near a four and so on . Percentage of error on some number is quite high, any hint or idea on how to improve this process? As far as i understand we can't do a training on this, nor on a general entity that could contain all possible number.

It seems from my point of view a fail in the voice recognition, may be there is somewehere (Dialgoflow or google action?) some parameter we can modify to improve the success rate?

Could be a godd idea input 100 or may be 1000 correct phone number in the training phase? (i don't think this is a solution the problem is not on the phrase but only in a part of the prhase that contain the number)

Any hint is welcome!! Thank you

After a contact with the support center, it appears that for number with format

+39 393 XXXX XXX

i.e Telephone number with format from E.123 E.123 is a standards-based recommendation by the International Telecommunications Union , the best way to limit error is to use @sys.number-sequence, but this don't support plus sign, so we use @sys.any with some control, substituting every word before the first digit with a "+" , removing every letter and checking for validity of number with google library..

Doin'g some test it seems that using a phone with a good michrophone the % of right number recognized is the same with sys.any and sys.number.sequence (without using the "+"). The support told us the "double3" i.e. 33 in number (or every other digit) actually is not supported (some times it seems to work fine but not too much)
