Plum IVR Support

I am trying to get the phone number that the person called... basically I am trying to get the IVR's phone number with my vxml. Is this possible?

Brent,

The variable
session.telephone.dnis
contains the number that the original caller dialed provided they did not withhold it.

Adrian

"Provided they did not withhold it"

How are they going to with hold it? it's not caller ID. I just want to get the phone number that your server is picking up on.

Is there a way they can withhold that? if so I need to be prepared for that.

thank you

Brent,

It is not possible to withold DNIS that is the number they are dialing and we would not be able to route the IVR call to your IVR application if DNIS was not available. Adrian was probably thinking of ANI, that can be withheld on local DNIS numbers, but it is very rare for it to be missing on a direct toll-free number.

Plum Support

session.telephone.dnis only gives me the last 4 digits. is there anyway to get the entire number?
i.e 6172222016

thank you

Hello,

There is no way to get the full 10 digit DNIS on the local Boston numbers this is a current limitation of the IVR trunks we are using. However, all toll-free number do receive the full 10 digit DNIS. Toll-free numbers run over separate trunk lines.

Hello,

I do not work for Plum Voice but I am very familiar with telephony and DNIS usage.

DNIS stands for 'Dialed Number Identification Service'. The DNIS digits applied to a number are arbitrary and do not necessarily relate to the actual digits used in the dialed number. However, It appears as though Plum Voice has assigned DNIS to a number based on what the last four digits of the number are. For example, we own over 1,000 numbers and we assign a DNIS to those numbers based on when we received them (the first number purchase was 1000 and the last one was 2807). To identify the dialed number we have to cross reference the DNIS digits with their appropriate number.

You are actually receiving the complete DNIS but you need to cross reference it to the appropriate dialed number. It sounds like you have a test account and have been assigned a local Boston number. On your main account page you should be able to see the DNIS and then you can cross reference those numbers to the appropriate dialed number using a table or various VXML statements.

Just so that I am clear on the limitations for capturing the full DNIS value in-app:

I get that DNIS will return only the last 4 digits when dialing in via your staging DIDs in Boston, and I get that inbound TFN calls will return a full 10-digit string value. What I am curious about is whether or not the 10-digit value will be available when using production DIDs that you offer: Can you clarify this for me please?


Thanks!

Matt

Hi Matt,

All local telephone numbers in Boston will be 4 digits. All toll-free telephone numbers will be 10 digits. That's a more straight-forward approach rather than thinking about staging vs production.

Hi there,

Thanks for your reply. I'd presume that you offer local DIDs outside of Boston, does he DNIS limitation apply to those numbers as well?


Matt

Hi Matt,

We primarily offer local numbers in the Boston area. We have the ability to get local numbers from other locales on a per-request basis. These local numbers would be 11 digits. The leading 1 plus the entire 10-digit number.

Thanks man, appreciate the confirmation.
