DNIS Digits 1

[tkinney]

Helloooo
I am switching LD Carriers and my extensions are 3 digits. According to our current carrier they send 4 digits to our DNIS by having a zero in front of the number. I really don't know why but anyway the new carrier is asking if my PBX drops the extra digit (zero)...I looked on disp trunk, disp DS1, sys para but I don't see this info anywhere. I'm assuming that the PBX does drop it somewhere otherwise the calls would never go through with 4 when my dial plan is 3??
Is there a reason they sent 4 instead of 3 and where can I see if my PBX is the deleter of digits?

Thanks,
Tina

Try looking at the route pattern, the calls use, when they come into your PBX. That is where you should see, how many numbers are deleted. It should say No. Del Dgts 1. That means the first digit is deleted when the number comes in out that route pattern.

Do not look at the route pattern, that is used on out bound calls, look in the trunk group on the third page for the

"INCOMING CALL HANDLING TREATMENT"
Service/ Called Called Del Insert Per Call Night
Feature Len Number CPN/BN Serv
other 4 1

This would look for all DNIS that are 4 digits in length and delete the first digit.

Maybe it's my version...G3siV6 but my 3rd page is administtable timers. I looked at the other pages and there is nothing about incoming call treatment! Could it be listed somewhere else. I tried Sys para fea(nothing) disp DS1 again nothing.

Thanks for the help

It's in the dial plan form. You state there that you have 3 digit extensions starting with whatever digits you use. The Definity then reads the last 3 digits of the dial string sent to you and matches it with whatever object it relates to.

So thats where it looks! O.K. then I can safely say that my PBX deletes the 1st digit sent.

Thanks!

Copy and paste the first page of your DID trunk group form into a reply to this thread. Remove any company specific information and the TAC.

The Definity is ignoring the leading zero. That T-1 is passing inband DTMF tones. And you can see that at the bottom of the page there is no Digit Treatment specified to Insert or Delete any digits.

That's gotta be an AT&T T-1, based on the name MEGA-SASS 2 way.

 

[tkinney]

It is AT&T T1 sorry I left that out in the first place. I'm so glad you could decipher that for me. For some reason my 3rd page doesn't list incoming handling. I will let the powers that be know.

Thanks again

That third page reference was for an ISDN/PRI T-1.

Good Luck,
