Problem with calls inn/out on uc560 with 4 isdn interfaces

Hello!

I am in a process of changing telephone central from Alcatel 4200E to Cisco uc560 with 4 isdn BRI interfaces. I currently have the alcatel central connected to
4 isdn devices (8 simultanious isdn calls), and plans to do the same on the uc560. I have about 30 internal/external numbers to use.

My problem is that when I disconnect the alcatel central and connect uc560, everything works great internal. But when I try to call in, I got busy signal.


When I try to call out to cellphones, I somthimes commes through, but most off the time I got "unknown number" in the SPA509G display.

Is there any spesific settings to consider when changing from the old central to uc560?


Do I have to change anything with my pstn provider to get this working?


Is there any spesific settings for Norwegian?

My settings for PSTN trunks on uc560:

BRI Switch Type: Basic Net3
Bearer Capasity: Speech
ISDN Static TE1: 4

ISDN related commands on the uc560:

Re: Problem with calls inn/out on uc560 with 4 isdn interfaces

There is a great deal of dial peer handling and configuration that you should only attempt if you are familiar with the UC500 CLI. My recommendation is that you use CCA to setup your inbound and outbound call routing. The CCA Admin Guide is available on:

http://www.cisco.com/en/US/docs/net_mgmt/cisco_configuration_assistant/version2_2_2/administration_guide/cca_222_sbcs_admin_guide.pdf

Thanks,

I have installed the uc560 only with CCA. But when it don't work,  I went to cli to watch and and paste into this forum. I also have some experiece with cli from routers and switches. But I see your point... -the entire cli config is about 2300 lines, so I don't want to mess it up to much in CLI... :-)

I see. You can post the entire config for us to look, but remember to remove passwords and private number, etc. Did you configure inbound and outbound Dialplans using CCA?

Re: Problem with calls inn/out on uc560 with 4 isdn interfaces

I configured everything with CCA.

Se the config in the attached file.

The five first number in the public number i have replaced with XXXXX

Passwords is replaced with *****

We use the 3 last digits in each emplyers public number as internal numbers on the phones.

e.g

Davids telephone:

internal 649

public XXXXX649

When someone wants to call David, They call XXXXX649

And when David calls someone, XXXXX649 is his called id.

Every call in that is busy or unaswered, is to be redirected to the operator number 640, not voicemail.

Re: Problem with calls inn/out on uc560 with 4 isdn interfaces

When I tested the uc560 against one single isdn test line earlier, it worked better. But I had just a single public number then.... Maybe there is something with the 4 isdn devices connected together and the isdn device settings on the uc560...

Re: Problem with calls inn/out on uc560 with 4 isdn interfaces

Can you get a debug ISDN q931?  I would like to see the inbound calls.

Hello!!

Sorry for late respons, but I was out off town... :-)

When I call in now, half of the calls from cellphone I get busy signal...

Se the log in the attached file. I also put in a picture off my "norwegian" pstn trunk settings. I have as mentioned before 4 isdn GT devices connected together.

Thanks!

Hi David,

Can you tell me if your Layer is set to permanently active or not?

Cheers,


David.

Hi David,

Call your carrier and ask them to make your Layer 1 permanently active, sometimes the carriers do not enable this by default (Well that is the case here in Australia), if the Layer 1 is not active, people get al sorts of trouble, so it is the first thing i do now before diagnosing other faults, 8/10 times the problem is fixed.

Cheers,

David.

Hello David,

It is set to active...

Anyway, everything seems to work now. The problem was some buggy isdn gt boxes...
