Route Inbound Calls via Area Code? 2

[pbxman]

Is there a way to do this?

We currently wish to route calls via inbound area code of the caller calling our call center, then report on it via CMS. Say our office is in NY and a caller calls in from area code 218 - we want our midwest division to handle this call and route to the midwest queue.

So is it possible, a major pain and unreliable, or no can do? If it is possible - would we have to switch to LD over ISDN and strip the inbound id then have some sort of table that looks for a match, then pass it along?
Thanks

It's a vector routing table. try add vrt next. then a vector would be:

goto vector 2 if ani in table 1 (midwest)
goto vector 3 if ani in table 2 (southeast)
etc.................

Well - that looks pretty easy..except I can imagine not having enough vrt entries to fulfill all the area codes (our G3si only has 100 slots for data per vrt and 10 possible vrt's).
So am I correct about having to use ISDN for LD as well? Currently we use LD AT&T tie trunks.

You need to recieve ani from your lec. Some can send inband while other's require isdn. vrt also accepts wildcards which may help you out. 10 x 100 = 1000. There are only 999 possible area codes.

Awesome - I didnt think of the 999 possible codes. The only restriction there would be labeling the VRT's and hoping say vrt's 1&2 (for east coast) contain enough entries. 218 is minnesota, and 213 is california, so wildcards wont help me there. This sounds doable with some planning though.
Thanks for the help, lopes1211!

Actually, nothing starts with 0 or 1, so it's 799.

..or 911.
I just found a link that said there were a total of 680 US area codes available for assignment so the number is becoming even more and more manageable.

You might want to check out the North American Numbering Plan website for the most up-to-date information on US, Canada, and Caribbean area codes, including ones that are planned but not yet active.

wow! That area code listing by location report will make my job a LOT easier - thanks Susan!

We do this too.

In the VRT, your entries look like the following:

(Disp VRT 14)
Number: 14 Name: -Your VRT Name Here- Sort? y

1: 201+ 17: 278+
2: 203+ 18: 283+
3: 207+ 19: 301+
4: 212+ 20: 302+
5: 215+ 21: 304+
6: 216+ 22: 313+
7: 219+ 23: 315+
8: 227+ 24: 317+
9: 231+ 25: 330+
10: 234+ 26: 339+
11: 240+ 27: 347+
12: 248+ 28: 351+
13: 260+ 29: 380+
14: 267+ 30: 401+
15: 269+ 31: 410+
16: 270+ 32: 412+

Thanks

If you don't get ANI from AT&T, vector routing tables aren't very helpful. You might also consider having AT&T build you a routing plan that would take calls from certain regions and deliver them to you with a different DNIS.

You could route all the VDN's to the same split/skill, and count them based on geography.

Incidently, area code 212 is in Manhatten, and 213 is Los Angeles. Know why?

When North Americans had to make long distance calls through long distance operators, the switching systems that the LD operators used had rotary dial signaling.

To minimize the number of rotations a rotary dial would do, they assigned the numbers with the smallest rotations to the areas they determined would get the greatest number of inbound calls. (Large population centers.)

It was designed to allow the operators to process more calls per hour.

Hence:

212 Manhatten (smallest number of pulses, 5)
213 Los Angeles (1 pulse higher, 6)
312 Chicago (same number of pulses as LA, 6)
.
.
.
808 Hawaii (26 pulses)

Silly telecom things....
