we have several dial-peer voip already config into our router. although what i dont really understand is the following issue.
we have a block of did's already config into the 2811 for example they start with 12374420XX and 12374424XX
voice-port 0/2/3
description FAX-3 1237442039 via PORT5
station-id name ABC company
station-id number 1237442039
caller-id enable
!
dial-peer voice 14 voip
preference 1
destination-pattern 24..
session target ipv4:192.168.10.11
incoming called-number 6T
dtmf-relay h245-signal
codec g711ulaw
fax rate 14400
fax protocol t38 ls-redundancy 0 hs-redundancy 0 fallback cisco
!
Now telco have assigned us with another blocks of did but they are not in the 123-744-XXXX these new did's are now 123-567-XXXX, my question is since the prefix have changed is the isdn call will be able to pass thru if i configure a dial peer such as the one already config into the router, ?
Thank you for your help

Hi, from what you told me, the new DIDs do not overlap the previous one. I think the destination-pattern I suggested before is specific enough to send only the right calls to the fax server, because it doesn't look at the first digit only, but also at the second. And, the original DID block starts with 20 and so is defined in destination-pattern.
03-30-2007 04:35 AM
Hi Charlotte,
Good question. Perhaps the first digit of the new block will be different, that is you are receiving four digits but meaningful ones are only the rightmost two or three.
03-30-2007 08:45 AM
well before i go into the 2811 and set up a new dial-peer i just want to know how am I going to do this since 123 XXX -9999 is different "XXX" than the ones are assigned to us.
Now can i just create a new dial-peer voip 18 with the new config?
Would this cause any problems in the incoming calls ?
Thank you again paolo
03-30-2007 08:52 AM
Well is not clear to me in what the new DID block will be different if they are sending only four digits ? For example if the four digitas of the new block all start with 25 the change destination-pattern of the current DP to CCM would be 2[45]..
Ask you telco about the exact definition of all the numbers assigned.

So as you see here in dial-peer voip 14, those calls are routed 192.168.10.11 which is the fax server. but the prefix is the same 123-944-24XX, so i can copy the same thing into for example dial-peer 18 same 192.168.10.11, but the block of dids that telco have give me this time is
123-405-1955 thru 1999
123-405-2370 thru 2398
123-405-2334 thru 2339
Signaling type (loop or ground): ISDN NI2
So as you see above it went from 123-944-XXXX to 123-405-XXXX ?...i wonder if is going to casue any problems, also how can i do this or configure this new set of did's into the 2811
thank you very much for your help. if you need anything let me, not only you are helping me but i am learning a lot with you
thanx again paolo
03-30-2007 10:28 AM
Hi,
123-405-1955 thru 1999
123-405-2370 thru 2398
123-405-2334 thru 2339
Now I don't know the impact of these on the your CM and extensions, but you can either add more DP to send call to the CM, or aggregate in one only:
destination-pattern [12][39]..
session-target xx.xx.xx.xx
of course if you have the fax/fxs dialpeer fully specified these will have precedence on the above.
destination-pattern 2339
port x/y/z
03-30-2007 12:43 PM
So the prefix 123[405]19XX will not affect the current configuration?. I mean the other prefix was 123 [944].
But according to the 2811 config that you have seen what will be the best route you will take to configure this did's and the commands you will use.
So will set the destination-pattern first or the dial-peer.
03-30-2007 02:30 PM
Well you can have:
dial-peer voice 10 voip
destination-pattern [124][39]..
session target ipv4:10.0.0.5
And that will send to CM any called that has first digit 1,2 or 4, second digit 3 or 9. That encompasses all your DID for now. You can make the destination-pattern less restrictive if you want.
Repeat this for less preference DP that goes to redundant CM. Number in square brackets are lists or range of digits, dot matches any digit.
The other DPs with pattern 20.. etc will become unnecessary and can be removed.
03-31-2007 09:01 AM
Well dial-peer voice 10 voip, already exists
dial-peer voice 10 voip
preference 1
destination-pattern 20..
progress_ind setup enable 3
voice-class codec 100
session target ipv4:10.0.0.5
dtmf-relay h245-alphanumeric
no vad
and I am trying to send the new did's to the fax server, so i would have replace the IP of the CM for the IP of the fax server in this case?..also the problem here is that the new set of block of did's the prefix is different, now let me ask you a question does the prefix means something to the router? for example
[123]405-XXXX
123=the area code
405=the prefix
XXXX=duffix
before all my did's were 123-944-xxxx meaning that the prefix was 944 now they have changed to 405 instead, now according to my dial-peer voice rules and destination-patterns that i see on the router all those are for 123-944-xxxx range?, unless i am wrong correct me please if i am missing something
03-31-2007 09:16 AM
Charlotte remember telco is sending four digits only. The router does not see the proceeding six digits. They number is irrelevant in router configuration
So all you have to do is to configure your DP based on that, pattern of last four digits.
Telco has gave you DID so they are unique.
The fun part may come when you want to originate calls and need calling number of 10 digits to show correct caller-id. You will to manipulate the "prefix" according to the calling extension... I guess we will talk about that another time :)
03-31-2007 08:51 PM
Ok what i dont understand is why telco only is sending 4 digits instead of all of them is this a normal practice for telco's?..if something goes wrong with me creating the new dial-peer and dial pattern do you think it will affect the normal call processing ? if something does go wrong how can i fixed? deleting the new dial-peer will do it?..oh yeah also how much would you charge me to give me some cisco lessons ? well i think you really know what re you doing so who else better than you, specially i would like to more about cisco ios and router configuration, thank you again for your time
04-01-2007 05:36 AM
Good morning again.
Why telco sends 4 digits only, you should ask them :)
Jokes apart, I've noticed that in north-america is common practice to send the DID digtis only, maybe as historical practice from analog DID, while other countries sends the full number.
If you mess-up things, changing back the configuration to what was before will fix. Often getting the right configuration is a bit of trial and error.
I cannot charge you anything Charlotte. If you want more advice you can use the email address that is in my profile (click the name).
Perhaps, buy a Cisco press book instead. I appreciate very much the nice words from you and others, good luck!
04-01-2007 01:10 PM
Paolo,
Well since i want to be really carefull with this did's configuration. Instead of creating another dial-peer voip 10, can i create for example a dial-peer voip 18 and a dial-peer voip 19 with the following configuration.
Now the fax server ip is 192.168.10.11 and the new set of dids are as follows
350-405-1955 thru 1999
350-405-2370 thru 2398
350-405-2334 thru 2339
Here is what i would do
dial-peer voice 18 voip
preference 1
destination-pattern [350][405]19..
session target ipv4:192.168.10.11
incoming called-number 6T
dtmf-relay h245-signal
codec g711ulaw
fax rate 14400
fax protocol t38 ls-redundancy 0 hs-redundancy 0 fallback cisco
dial-peer voice 18 voip
preference 1
destination-pattern [350][405]23..
session target ipv4:192.168.10.11
incoming called-number 6T
dtmf-relay h245-signal
codec g711ulaw
fax rate 14400
fax protocol t38 ls-redundancy 0 hs-redundancy 0 fallback cisco
If I am not mistaken this config will forward all dids to the fax server Do you think this will do it?
thank you again for your time
