Hi,
The CME will be installed on UK London. The customer wants to have Calling of restriction based on the dialed number. So basically we need configure COS for the users.
Is there any specific dial plan available for UK London area? Although someone also asked the similar questions.
Thanks,
JJ

Hi,
A basic COR config shouldn't be too complicated:

Thanks for your post. It is helpful.
I am trying to use the following dialplan for calls from London area:
Emergency Call:
999
112
Local call:
020XXXXXXXX ---forward 11 digits
Longdistance calls
0[1-9]XXXXXXXXT forward 10 digits
0[1-9]XXXXXXXXX forward 11 digits
International to NorthAmerica
001[2-9]XX[2-9]XXXXXX forward 13 digits
Other international calls:
00T prefix 00
Can anyone point out if I am wrong?
Thanks,
JJ

Hi,
proper dial-peer config is more an art that a science, fortunately is not that one has to got everything right for a normal working.
Points to note:
for emergency and other numbers then are matched in full, remember to put "no digit-strip¨ or "forward-digits-all"
Then the big decision is if you want to use a prexif digit to access outside lines, or not. I'm not 100% sure if that's possible for the UK as I havent looked in suffiecient detail.
Anyway, there are few improvements you can make here and there:
dial-peer voice 80 pots
description International excpet country code 1
destination-pattern 00[2-9]......T
prefix 00
etc...
Then there are few tricks that I'm not sure if are in any book, eg:
Prevent digit absorbing still matching exact numbers. That is, no need for "prefix"
destination-pattern 9[0][0][1][2-9][0-8].[2-9]......
That is for N.A. 1 using 9 as access digit with strict NANP check.
All really depends on how much control you want!
Thanks for the nice rating and good luck!

You can then simply create your dial-peer cor list restrictions and assign them to an ephone-dn, for example:-
dial-peer cor list CSS-Unrestricted
member Local
member Emergency
member National
member Freephone
member Mobile
member PremiumRate
member International
member DirectoryEnquiry
member Internal
ephone-dn 1 dual-line
number 1234
corlist incoming CSS-Unrestricted
corlist outgoing InternalPT
Hope this helps

In addition to the good info give by Allan, also note that for COR to work as desired, it is not necessary to pervasively configure corlist for each and any DP and ephone-dn.
This is due to two important properties of COR:
1st: if no corlist is present on the incoming or outgoing DP, there will be no restriction.
2nd: you can use "empty" corlist as well, again useful to reduce the configuration needed.
So, for example, when we want only block international calls from a certain phone:
dial-peer cor custom
name dummy
dial-peer cor list international-in
! note there are no members in this list
dial-peer cor list international-out
member dummy
dial-peer voice 110 pots
corlist outgoing international-out
! note country code cannot begin with 0, and at least some digits must be present
destination-pattern 900[1-9].....T
port x/y/z:15
prefix 00
ephone-dn 1 dual-line
corlist incoming international-in
Hope this helps, please rate post if it does!

Hi Allan,
Can you please let me know the dial-peer is for international calls?
dial-peer voice 102 pots
corlist outgoing InternationalPT
translation-profile outgoing Outgoing
destination-pattern 915.
port 0/2/0:15
prefix 1
!
Also from Paolo's pointed document, if calling from London where the CME sits, the local calls should also include the 11digit pattern of 9020XXXXXXXX, right? Calling from London, is there any 6 digit as a local call as your dial-peer 103?
Thanks,
JJ

Dial-Peer 113 is the International DP which matches the called number 900T.
Your local dialling will be dictated by which area you are within the UK, as there are 5,6,7 and 8 digit numbers, therefore you will need to revise the local DP (103) to forward the appropriate number of digits, you will have to adjust the destination-patter accordingly.
You may find that there are both 7 and 8 digit local dialing so you will need to configure the patter for eight digits. What you need to be aware of is that the interdigit timeout will come into effect if you are say dialling only 7 digits.

Allan.

Calling from London, is there any 6 digit as a local call as your dial-peer 103?
Within London, local numbers are always eight digits and begin 3, 7 or 8.
London NDO numbers begin 0 or 1.
Your local dialling will be dictated by which area you are within the UK, as there are 5, 6, 7 and 8 digit numbers...
Local numbers in the UK use 4, 5, 6, 7 or 8 digits.
Area codes use 2, 3, 4 or 5 digits.
Total number length can be 9 or 10 digits not including any 0 access code or +44 country code digits.
You may find that there are both 7 and 8 digit local dialing.
Nowhere in the UK has a mix of 7 and 8 digit local dialling.
One area code has a mix of 4 and 5 digit local dialling and forty area codes have a mix of 5 and 6 digit local dialling.
