Hi Guys,
I really need some help with the configuration of 3 ISDN BRI circuits in Europe.I have a 2800 series with 3 bri`s in the back which the site will use for incoming and outgoing calls.I have never setup BRI`s before only E1`s so not sure where to even begin.If someone could please point me in the right direction or perhaps give me an example of what my config should look like it would be much appreciated...thanks in advance!!!

Hi There also have the same problem. Using a 2800 with 4 BRI ports connecting to Premicells to allow outgoing calls to the different Mobile operators in South Africa. If you come right please give me shout, if I find something relevant will let you know
Thanks
Shaun

You can use the configuration I suggested.
The most important thing you've to find is if your premicell devices require router to be network or user side, and if static tei is required. Possibly they can work both ways, just configure router accordingly.
After that, you troubleshoot with "debug isdn q931" and "term mon".

Ar the lines in hunt-group ? If so the config will be likely:
int bri 0/0/0
isdn switch-type basic-net3
isdn static-tei 0
trunk-group bri
isdn overlap-receiving <--- not always required, but doesn't hurt
ised sending-complete <-- same as above
int bri 0/0/1
dial-peer voice 111 pots
destination-pattern 0....T
trunkgroup bri
Note in many countries you can also eliminate the prefix digits (0 or 9) for external calls. Just make you extension all begin with an unused digit. users like that very much because it's "like calling from home".
Hope this helps, please rate post if it does!

Hi Brilliant !!
Just what i needed. I can now see the calls come in on debug q931 but when i added the trunk group bri to my pots dial peer the calls got rejected.Once i removed it,the call comes in as normal but i then get a type of dial tone when calling in ...appreciate your help,been on this for ages now ....

There are incoming and outgoing DPs. the trunkgroup is for outgoing ones and you need it there, remove any port command you ad first.
For incoming, normally you have
dial-peer voice 1 pots
incoming called-number .
direct-inward-dial
However to ring the destination phone, the called number must match extension. This is either with a translation-profile, or dialplan pattern under telephony-service. The details varies with each installation and country.

At the moment if i call in from my mobile i can see the call come in but i am still getting a dial tone on my mobile.I need to translate the incoming 9 digits the carrier is presenting to four digits.All the call manager config is done and i have one DN setup for testin.

Hi,
compare the "incoming called-number" on DP 30 with what you receive from telco as "debug isdn q931", they have to match. Or just use ".". Else you get dialtone.
The DP thing take a little to be understood, after you'll be OK.
04-09-2008 05:18 AM
Calling Party Number i = 0x0183, '3391721202'
Plan:ISDN, Type:Unknown
Called Party Number i = 0xA1, '544683500'
Plan:ISDN, Type:National
They seem to match from the output.do i not need to do anything on the voiceports or create some translation rules.
04-09-2008 05:23 AM
Yes they match. The call should be getting to the CM, it seems strange that it gives dialtone but I cannot exclude that. Check with "debug voip dialpeer".
04-09-2008 11:58 PM
There is no match on debug dial-peer and the output from the sh DP voice shows operation state & outbound state as down :

Admin state is up and that's what matters.
Oper state is down due to no active calls. Outbound is down due to lack of destination-pattern and port, however being this an incoming DP, that doesn't matter.
Do you have any translation rule ? Try "incoming called-number ." as suggested above.
04-10-2008 12:57 AM
The incoming called number is added to the dial peers.I dont have any translation rules setup.
This is doing my head in :-)
04-10-2008 01:36 AM
I added the port numbers to the dial-peers and am now able to receive calls but unable to make any.
