Point to "DNIS XXXX"??

[techguru69]

Hi all,

Our 800 number carrier has been sending our 800 number calls through the local telco via a terminated T-1 switched and then to a hunt group on our Prologix. They claim we can save mucho $$$ if we "change it to unswitched and program the prologix so that our 800-xxx-xxxx number is set up with DNIS 1234". I tried asking them how to do this but they nothing about Avaya PBX's.

Anyone have a clue, or should I resort to my very expensive Avaya service?

TIA

When an 800 number arrives on your PBX with a DNIS digit, the PBX treats this DNIS just like any other extension number. You could give them the existing hunt group extension number as the DNIS digit to use and the call would go to the hunt group just as it does now.

The key here is do your homework and you tell the phone company what DNIS digits to use for your 800 numbers. If you let them assign the digits, you might be stuck trying to make a number work that does not fit your dialplan. You can do it, but some front end planning eliminates lots of digit conversion issues.

From what you have described, it sounds like the 800 number carrier is sending your 800 number to a regular phone number. This is how switched is usually set up. Usually switched costs more than unswitched(or dedicated), so they are probably correct in saying you could save money by changing to dedicated and setting up DNIS.

I agree with phonepd above on planning what numbers you use for DNIS digits. I would also consider making the DNIS a VDN instead of the hunt group extension so you can easily re-route the calls to a different destination if you need to by just switching the vector assigned to the VDN.

If your T-1 is a ISDN-PRI you can have them send the last four of the 800 number as the DNIS. On page three of the trunk form you can convert the DNIS digits to better suit your own dial plan and even down to three digits. Wisdom is Knowledge

Thanks All Phoneman2

To use the DNIS as a VDN would be making the assumption that you have the RTU for Vectoring turned on. If you do have vectoring, by all means use VDN. Vectoring is that answer to the most flexable solutions.

I do not agree with using the last four digits of the 800 number as the DNIS, UNLESS they just happen to fit your dialplan. Avoid digit conversion if you can. When doing something new, always get digits that fit your dialplan. Save digit conversion for fixing someone elses poor planning.

I agree that dedicated service is usually WAY cheaper than switched, but you would need to check the costs of both, and total volume. You indicated a single t-1 (which might have been for description purposes) that tells me your total call volume is low. You would need to calculate total 800 call volume * the difference between switch and dedicated to come up with the per call/min savings. Then include the cost of the dedicated t-1 montly charge, and the addtional t-1 board and CSU needed for the switch.

Almost always the cost of the t-1 and equipment will be a non issue compaired with the savings over dedicated verus switched, but again it would depend on the total 800 volume, and how long you look at the ROI of the extra equipment.

Just some random thoughts for friday, everyone have a nice weekend.

In my opinion, best way to receive DNIS is as VDN and then route the call thru vectoring.
