Dialplan/AAR/ARS Configuration 2

[phonebits]

Hi All,

I'm trying to build out a lab system running CM 6.3 and AAM 6.3 and I'm running into some difficulty in figuring out how the dialplan/AAR/ARS should be configured for my purposes. My setup is kind of unusual being that it's in a lab and co-existing with a number of other PBXs from different vendors and I like to keep it all interoperable.

I've read all the documentation I could find that seemed relevant, but I'm still scratching my head. I'm so used to the Nortel CS1000 way of doing things, and I've got a CS1000 configured pretty much exactly the way I'm trying to get Aura to work... but they're obviously very different creatures.

The way I'd like it to work is for Aura to be attached to my Cisco CUCM server via SIP (or h.323, whichever is easier) and have Aura send 9+ 11 digits for outbound calls to CUCM for routing out to my SIP carrier. I'd also like Aura to route 6 digits to other lab systems I have networked, those extensions are all 7X-XXXX and all 6 digits should be sent to CUCM. Inbound calls come in as 10 digits from CUCM. I also need to be able to dial some 4 digit extensions on other systems that start with the leading digits 4 and 6, also being routed to the CUCM. The local extension ranges on Aura are 57XX and 58XX.

To complicate matters I need to accommodate the trunk the AAM, which I'm having a rough time setting up the switch link for.

I guess my question is which features I should be using (AAR/ARS) and what I need to do to make sure the system correctly recognizes the call types as private/public etc. I'm sure I could eventually come up with something that's functional, but I'd like some advice so I can build this out the correct way.

Any pointers would be enormously appreciated.

In "change dialplan analysis", the private extension ranges should be in there as either ext or udp.

Then, in "change dialplan parameters" you can have dialed strings looked at by udp before ext, or ext before udp.

Then, in udp, string 7, min/max 6 should map to aar. aar match string 7 min/max6 to a route to cucm. That route should have lev0-pvt in the bottom right to define private numbering.

If 9 were your ARS code, then 9 gets you to the ARS table where string 1 of min/max11, calltype pubu or unku or fnpa goes to a route to perhaps the same SIP trunk to CUCM with the bottom right having a non-private numbering type.

If you nail it up just right, you can call over the same trunk and send your short extn when calling private numbers and send your public DID when calling thru ARS.

They made a change in how the PBX decides public vs private numbering in 1 parameter at 1 layer. This support notice describes it, but also at a high level how all that numbering is determined. It'll make your head spin, but if you get this, you get it.

Either way, either you dial the ARS or AAR code first to get to your digit analysis, or you leverage UDP. You then pick if the PBX looks first at extensions or UDP. If you have a extension and UDP the same, that config in dialplan parameters decides which gets preferential treatment. You might make that decision in a real environment based on whether you're migrating users on or off your system, whether you're adding sets ahead of time if adding people, or ever removing sets if you migrate off. Telling the system which order to look in can be helpful. Either way, you should be able to figure it out.

So just to confirm what I'm thinking...

If I use AAR, I would need to dial an access code to hit the 7X-XXX and 6XXX or 4XXX? But if I use UDP I can dial them as if they're on-switch?

I have "ARS/AAR dialing without FAC" turned on in customer options. I'd like to dial a 9 for outbound calls to the PSTN but have everything else dialed without a leading FAC digit.

Am I on the right path here?

That's right.
So, udp would match the strings you want to send to aar. 9 would be in "dialplan analysis" as a "fac" and you'd "change feature-access-codes" to make 9 the ARS code.

You should have a aar code too even if you won't dial it yourself. The system kind of uses them in the background whether a human dials them at a keypad or not.

And if you got your calltypes and numbering formats right, you could use the same trunk to CUCM for private dialing/numbering and public dialing/numbering.
