understanding VDN and PRI 2

[asguyas]

Hey guys long time Nortel tech, now in charge of a Avaya Definity and about to upgrade to CM 6. we currently have CM 5.2. To get to my point I have learned a lot about the switch and have figured out a good chunk of the programing thanks primarly to this web site. However I just can not figure out how PRI number 455-555-1212 arrives at ext 4840. I think I am getting lost in nortel language and Avaya terms. Is there an easy explanation, or could someone post an example? If this is fairly complicated to explain, please say so.

They may be using the Incoming Call Handling Table to manipulate the digits. Try doing 'display inc-call-handling-trmt trunk-group x', where 'x' is the PBX trunk group number, to see what's assigned.

Thanks for the reply, but no info there.

 

[sekitori]

perhaps check the ARS coversion tables;

ch ars digit-conversion x(x=1,2,3,4 etc.)

Put a trace up on the trunk group (list trace tac xxx) and dial the number. You should see the digits being delivered by the carrier. They may be doing digit conversion in their network.

Inbound numbers have a DNIS sent by the phone company to your PRI. This is what the PBX receives as the incoming number.

Regardless of what the last digits of a number is, say 1212, the phone company can make it send whatever you want. Apparently this 1212 number has a DNIS of 4840, so that's where the phone system is routing the call. It sees DNIS 4840 and dials extension 4840.

If you don't want it to route to 4840, you can change your incoming trunk handling table for that trunk and convert it to what ever you want.

Quoting only proves you know how to cut and paste.

Display trunk-group XX
then look on about the 3rd page for incoming call handling treatment.
When the public network hands you a 4 (more or less) digit called number it will route it to an 4 (more or less) digit station.

INCOMING CALL HANDLING TREATMENT
Service/ Called Called Del Insert Per Call Night
Feature Len Number CPN/BN Serv
public-ntwrk 4 1212 4 2198
public-ntwrk 4 6440 4 2170
public-ntwrk 4 6494 4 2170
public-ntwrk 4 5599 4 5490
public-ntwrk 4 1210 4 4038
public-ntwrk 4 4842 4 4842
public-ntwrk 4 1140 4 4843

In this example when the public network hands me the 4 digit number 1212 it routes it to a 4 digit station 2198.
Hope this helps.

appreciate all the response, but still not displaying how the orginal programer did them. Most be doing them through a route of some sort. I will keep digging thanks.

asguas.
I think Bosker explanation explains it.

you receive 1212 from the network and you tell the system to translate it to 4840.

also have a look at these Tutorial videos
