NEC IPK II Call flow questions 1

Hello,

I am currently managing an NEC IPK II PBX. I've done a decent amount of reading/investigating to identify how calls flow in our system but a few things still elude my grasp. Calls come in on Trunk Group (CMD14-05) and that rings virtual extension 301 (CMD22-07). After 18 seconds (CMD22-01-04) the call transfers to System Mailbox 001 but I have no idea how this happens as (CMD24-09) for Ext 301 is set to “No Call Forward”. After that the message for mailbox 001 plays and then transfers to virtual extension 300 (CMD47-13 “Timeout”??). Then the call rings with a different ring tone on all stations that have a Virtual Extension Key = 300 (CMD15-07) and has ring assignment selected in (CMD15-09). Now I have read a few forums that state (CMD22-01-04) is the timer for sending incoming calls on POTS lines to the Auto Attendant. If this is true, is there any other configuration that ties VEx 301 to System Mailbox 001 or is the Auto Attendant automatically on 301?

The other mapping I can’t wrap my head around yet is the ring group. Most of our phones ring on incoming trunk calls because they all have VEx 301 as function key #1 (CMD15-07 & 15-09) yet in (CMD22-04), several extensions are listed in ring group #1. My phone rings occasionally with a different tone but none of the function keys light up. Is this because i'm listed in (CMD22-04)?

Also, In (CMD22-05), all trunks and modes are = 1. In CMD22-08 though, Truck 1-4 = 102 (I don’t think 102 references an extension) yet all other options are = 1. Now the language here doesn’t say Trunk groups, just trunk so would that mean that the other two trunks (5&6) are not being used here or misconfigured? CMD22-07 has Trunk 1-7 all set to VEx 301.

To me it feels like I am missing a few CMD locations to tie all of these things together. Any insight or assistance is appreciated. Thank you for your time!
 
If 22-02 is set to normal, then it follows 22-05 + 22-04. If 22-02 is set to DIL then it follows 22-07. 300 + 301 are probably virtual extensions placed on buttons and assigned to ring and/or delay ring. That is because department groups do not function well when a member is forwarded to their voicemail. The member is essentially taken out of the group unless the forwarding is cancelled.
22-08 is used for both DIL and incoming ring groups. It functions with both normal and DIL settings and uses the timer in 22-01-04.
22-08 set to 102 (not extension 102, but 102 is a ring group to go to the auto attn)
 
Hello Belevedere,

Sorry for the delayed response. So in 22-02, it is set to DIL. So does that mean the config in 22-04 & 22-05 is ignored/not applied?

Following your explanation, in 22-07 shows 301 for Mode 1. After that rings for the duration set in 22-01-04, it transfers to 102 configured in 22-08. 102 is a ring group for the auto attendant which is System Mailbox 001? How is 102 tied to 001 and how does 001 connect to 300 after playing the message?

Also, we have 7 POTS lines from Telco but in 22-08, only Trunk 1-4 is set to 102 yet in 14-05, Trunk 1-7 are all in group 1. Should I change 5-7 to 102 in 22-08 to match the other trunks?

Thanks again for your expertise!


 
Hello Belevedere,

I think I found how 102 transfers to 300, 47-13 option 0 or Timeout? Once connected to the auto-attendant, is that where the system mailboxes (001,002,003 etc) come into play?

Thanks again!
 
After it transfers to ring group 102 (AA), it looks at 47-12 for any scheduling. If not set it looks at 47-11, default mailbox. In these fields, it is probably set to routing - box 1 (001), or 2 (002) etc. In 47-08 the routing box points to a dial action table 47-13. That is where the 1 key dialing options are set. Usually set to unscreened transfer to an extension. GOTO only sends the caller to another routing box.

[Also, we have 7 POTS lines from Telco but in 22-08, only Trunk 1-4 is set to 102 yet in 14-05, Trunk 1-7 are all in group 1. Should I change 5-7 to 102 in 22-08 to match the other trunks?] -- Only if you need those trunks to act the same way as the others. Also note 47-10 can send individual trunks to different routing tables.

[So in 22-02, it is set to DIL. So does that mean the config in 22-04 & 22-05 is ignored/not applied? ] -- yes.
 
Hi again, a few more questions, is there a way to access the AA for testing the setup other than calling in from an external line and not answering it? Instead of the AA sending the call to virtual extension 300, can i have it dump to the hold queue and then light a function key on the phone? In the hold queue, are there any options? Thank you again!!
 
To properly test the AA settings you need to call in from the outside. The only alternative is to loop a SLT port to a trunk port.
I'm not sure what you mean by dump to hold. I do not recall that being an option. Through the dial action table you can send it to take a message and light a light on a button set to inskin VM.
 
Thank you for the quick reply. I was wondering if I could send/transfer a call to the hold queue or even just send it to an extension that has no call forwarding setup, and change what the caller hears from ringing to the MOH?
 
Sounds more like some type of ACD you are looking for. You can change your music on hold source per trunk but if its a circuit that's almost impossible to work the way you are talking without ACD
