Call Routing Question - Nortel CS1000 1

[EugeneMc132]

Hi,

I'm a regular reader, but a new poster, and could use some help with something I'm working on. I have 3 sites, 2 of them have CS1000's and the third has a BCM400. We have routing setup through CDP to send calls between the sites using H.323, and it works perfectly. My question is, as one of the sites is out of state, I'd like to intercept calls that have been placed to the 10 digit DID numbers between sites over the PSTN, by stripping off the 1-xxx-xxx, stick on the CDP steering code and route over the H.323 trunks. I've built the DMI entry and the RLB, but I'm having difficulty with matching the digits to steer calls to the RLB I've created. To be honest, I'm not really sure that this is even the right approach. I've done digit manipulation like this before (i.e. intercepting 411, inserting the 1800-466-4 in front of it and sending to the pstn to get to Google's free 411 service), but I'm a little perplexed on this one. Any help would be greatly appreciated.

Thanks!!

I think you want to use "ARRN" to get the specific range of numbers within the other NPA pointed to the "Alternate Route List" that calls your H323 route.

ARRN only works with SPNs, so you need to OUT the NPA and NEW it as an SPN - takes a second is all. Just use the same settings. Then you can use ARRN, which is explained here:

Thanks Gene, this looks exactly what I am looking for. One problem though. When I create the SPN, I am not given the ARRN or ARLI prompts. I did a little digging, and found another thread talking about ARRN

http://www.tek-tips.com/viewthread.cfm?qid=962253&page=961

and was checking some of the things that are talked about, like making sure pkg 160 is loaded (it is), and printing the ESN in LD 86 to check the MXSD values. Here is that section from my switch. I'm sure this is why I'm not getting the prompts. Before I make changes here, I'm not really sure what the ramifications would be. Any insight would be appreciated.

At the SDRR prompt, enter ARRN

 

[GHTROUT]

Everyone Rls 25 and later has ARRN...

As Reusser indicates, you type it at SDRR

Thanks for that. Tried it, and it gave me an ESN080, which says "No more available SDR blocks (out or expand MXSD)". Looks like that MXSD value of 0 ain't cutting the mustard as they say.

 

[GHTROUT]

Ah, I see. There is no risk in this minor LD86 ESN change.

Yep, that's exactly what I did, and it worked to get the alternate routing in. Getting a busy signal when I'm dialing inside alternate portion of the routing, but everything else outside of it in that area code works fine. Gonna do some TRAC's to see what I'm missing. I'll post what I find. Thanks again to you guys for your help!!

 

[EugeneMc132]

SUCCESS!!!!!

The busy signal was because I hadn't changed the CTYP in my DMI table to CDP, so it was still trying to shove it out over the PRI. Once I did that, bingo!!! I feel like singing!!!

Thanks again guys for the help!!!
