2821 PRI config help 1

[Eitsalo]

Hi, I have been working with Cisco 2801 having analog lines assigned to FXS ports and then manipulate however/which ever phone I want the assigned FXO port phone number to ring on the phones.
Example:
voice-port 0/3/3
echo-cancel coverage 32
connection plar opx 3155
description 447-332-5558 HelpLine
caller-id enable
I have to configure 2821 having T1 with 30 DID. Some DID will be assigned to staff direct number and some will be be directed to auto attendant (CUE). How do I configure and assigne the DID numbers without knowing the voice port?
Thanks in advance..

Since you mentioned CUE are you running CME with IP sets also? If so, you create the ephone-dn's and assign them to the ephone's buttons. The ephone is actually like a 'phantom or virtual' port. Here's an example for a CME:

ephone-dn 9 dual-line
number 2007
label 2007
description User Seven
name User Seven
call-forward busy 6000
call-forward noan 6000 timeout 15

ephone 7
username "user7" password 2007
mac-address 0000.0000.0007
paging-dn 2
type 7960
button 1:9

There is a lot more programming for a CME. This is just an example of the ephone-dn and ephone config.

Thank you pndscm, yes we're running cme with ip sets. I understand the "ephone dn" and "ephone #" how they're assign to phone. My question was how do I assign a certain DID number ie 222-2345 to a certain phone?

 

[pndscm]

ephone-dn 9 dual-line
number 2007

ephone 7
mac-address 0000.0000.0007
type 7960
button 1:9

When the system sees the number come in, it will ring the phone. If you are getting more digits than you are using ie, 222-2345 and your extension is 2345, you can trim off the excess using num-ex command as in:
num-ex 222XXXX XXXX

Hi, I am trying to configure the T1 DIDs on 2821 as below

dial-peer voice 1 pots
port 1/0:23
incoming called-number .
direct-inward-dial

and getting an error on port "1/0:23"

So I run a sh ip inertface command

MARGTAVG01#sh ip interface bri
Interface IP-Address OK? Method Status Prot
ocol
GigabitEthernet0/0 unassigned YES NVRAM up up

GigabitEthernet0/0.21 172.xx.xxx.x YES NVRAM up up

GigabitEthernet0/0.121 172.xx.xxx.x YES NVRAM up up

Service-Engine0/0 172.xx.xxx.x YES TFTP up up

GigabitEthernet0/1 192.xxx.xxx.xx YES NVRAM up down

SSLVPN-VIF0 unassigned NO unset up up

MARGTAVG01#

I tried port 0/0:23, 0/0/0:23 but did not work and still got the same error. What is right interface card number the T1? and how do find that out please.

Thanks in advance..

I don't see a Serial port in you output.

Did you configure the controller T1? Here is a sample of some of the necessary commands:

network-clock-participate wic 2

isdn switch-type primary-ni

controller T1 0/2/0
cablelength short 133
pri-group timeslots 1-24

(Remark this will create the next interface)

interface Serial0/2/0:23
no ip address
encapsulation hdlc
isdn switch-type primary-ni
isdn incoming-voice voice
no cdp enable

At this point your port will be

dial-peer voice 3 pots
description ** T1 PRI pots dial-peer **
incoming called-number .
direct-inward-dial
port 0/2/0:23
