PBX - Cisco voice card

[kcbell]

I just installed the following:

Definity T1 -->Cisco 3640 Voice Card -->Leased Line --> Cisco 3640 Voice Card ---> NEC PBX

The Definity is in the US and the NEC is in Asia.

Problem 1: When I dial to Asia. I cannot hear ringing tone but the other side pickup the phone. I suspect it is the problem at the other side.

Problem 2: How to I program the PBX to allow user to dial "8" to get to one trunk group only but not using ARS?

Any more information is needed, please let me know.

 

[BuckWeet]

Are you doing ISDN to the cisco?

you might need to setup the progress indicators on the dial-peers under the router..

 

[kcbell]

No. It is just a regular T1. I can call Asia and they can call us with no problems. In fact the quality of call is excellent with 160ms latendcy. Ringing tone is one of the several issues that I like to get resolve first.

 

[satman5152]

Are u using VOIP on the Cisco, which IOS is on the 3640?

What is the Tru type; Tie, Co or Tandem? in or out or both ways?

What is the NEC Expecting? CO, tie ??

problem 2, I use AAR to route special traffic, access to AAR is *88, programable under Fea acc codes.

 

[tektips71]

another way to use 8 to get access to the trun is by using the 8 as a TAC code for that trunk .

second option if you have private networking RTU released , then you can use AAR tables and routes and 8 as AAR code .

for the ring back i belive it is something to do with the far end pabx or the cisco .

I think Cisco voice card is before VoIP. However, since voice packets are packetized and send over via International Privite Leased Circuit. I think you can call it VoIP. The IOS is 12.xx. I am not sure which version but it is the one that works with voice card.

Trunk is "Tie" and two-ways. You'll find application notes at Cisco talks about voice card and Lucent PBX. However, there is no explaination of each command.

The NEC is expecting Tie line.

ayman:

I tried to use '8' as the TAC but the PBX is not accepting it even after I modified the dial plan 1st digit '8' as misc. I could tell the users just to dial the three digits TAC if I cannot get the '8' to specify trunk group.

I agree that the ring back is from the other end.

Another issue is how do I get the PBX to show what number I am dialing after I dial the TAC. All other trunks work fine except the new trunk to the IPLC.

Thanks for all the help!

kcbell:

Change Feature access code to 8 for AAR, cha dial plan to 8 is a feature. (fac) then 8 will point to your AAR. I assume u r not using 8 for anything else.

I hv a 3660, and i do Tie lines also on T-1, over satellite, for your DS1 setup are u sending all 00000000 as the idle code to the NEC? This is one place to look as some people like all 0's and some set all 1's, I use all 0's.

Which Card do u hv from cisco for the T-1 interface, i will try to set my system up like yours and see if i get the same trouble u hv.

R u running Enterprise IP SEC, or IP PLUS on your cisco?
login to the Cisco and do a "sh ver"

best rgds,

I am able to change the TAC to 8 and it is pointing to the T1 at the router. However, after I dial '8', I don't see the digits that I dialed on the display as well as the PBX is not sending any number to the Call Accounting Software. If I use '9' with ARS programmed to go to that trunk, I am able to see the digits that I dialed as well as all digits shows up at the CAS.

I am running all 1's as the idle code since it is the default. I am able to make calls and receive calls. I am not able to hear the ring back tone.

The card that I use is the Cisco Voice Card NM-HDV-1T1-24 T1 running 4 wires directly from the Lucent PBX TN767E to the voice card.

This morning I was able to make a call from West Coast to Asia and back to west Coast. I beleive the latency must be about 320ms and the call quality was better than most cell phone.

Following is the sh ver of the 3640.

Have fun!

Well first things first, if you're doing just a T1 tie line to the NEC system. In the routers you need to be doing a "connection trunk" type of connection. So basically when you go off hook on the definity, the router detects this, then brings up a full path connection to the far switch. Therefore you would be pulling dialtone from the NEC and not letting the router decide its path via dial-peers. This should fix your ringback problem. Also make sure that they're all e&m wink start or whatever.

Then on your definity, setup a FAC of 8 for the ARS secondary code. Then on your ars setup the # that you want to go over the trunk. This is the only way to get the digits to display.

Following is the hardware configuration of the project.

Definity T1 -->Cisco 3640 Voice Card -->Leased Line --> Cisco 3640 Voice Card ---> NEC PBX

The trunk group that I setup is Tie between Definity and the Cisco Voice Card.

I know how to add an '8' as secondary FAS to trigger the ARS. "ch fea" form will allow an '8' works like a '9'. But how do you trigger the ARS specifily for this trunk to Aisa by dialing '8' instead of 9?

 

[BuckWeet]

No real way to tie the 8 to that trunk only. What is the real reason for that though, because if the 8 fails, you want them to use the 9 instead. Also the routers need to be configured as "connection trunk" under your voice-port settings.. Post your configs and I can help you on the router side. I've done a few definity to definity via T1 like this, and using an external PPP datamod to do the DCS, works great..

I will do that on Monday. Have a happy 4th of July!

Following is the config on the 3640 router with the voice card. I am using 384K for voice calls on a data T1.
The prefix that they use in Asia is 7xx. I want to use '8' to identify that when '8' is dialed before the 7xx. The PBX will route the call to the T1 data line to Asia (toll-bypass). If someone dial '9' then 7xx-xxxx, these calls will route to the PSTN as local calls.

Following config is simplied and it has all config regarding to voice.

What this does is when one side picks up a trunk, it builds a connection immediately to the remote end switch, and you'll pull dialtone off the remote end. This way you won't have to deal with ringing issues, etc..

Do you have UDP enabled in your switch at all, let me know. If you do then we have a few options to explore. WE could manipulate the AAR table to do what you want possibly..

Let me know

BuckWeet

 

[BuckWeet]

oh also, do you have the private networking RTU assigned?

 

[kcbell]

Buckweet:

Thanks for the posting. The PBX is not IP enable.

I think I understand what you are doing with connection trunk. Is the 1111, 1112 and 2221, 2223 arbitrary? Since the other end is in Asia, I have no access to their router. Can you think of what other thing that I can do on my end to make the ringback tone works? If nothing, I will suggest to implement the way that you suggested. Thanks

KC

 

[BuckWeet]

Yes its arbitrary, make it whatever you want, as long as they match up.

I didn't mean to say if the PBX is IP enabled, I'm asking if it has the UDP and Private networking RTU turned on. That way we can manipulate the AAR tables to do the 8 feature like you're looking for.

Also, you might check the country code settings on each router. That could be the cause of the ringback issues, but I'm not sure how it will react with different settings on each end.

[kcbell]

Buckweet:

Please tell me how to check UDP and Private Networking RTU. These are new to me.

I did set the cptone to US in my router. Is it what you are talking about country code?

Thanks

KC

 

[BuckWeet]

yes, the cptone, is the remote end set to the proper coding

for the RTU's do this

disp sys cust

it'll show your customer options, depends on the version of switch for these RTU's

but UDP will be called "uniform dial plan" and the other one is just private networking..

 

[kcbell]

Buckweet: Here is the disp sys cust. I guess both of them are 'n'. KC
