UK Local Dial Plan

Hello,

I am setting up a branch office in the UK communicating to centralized CCM in the states. What dial plan for their route patterns should I implement?

I typically use the 9.011! and 9.011!# in the past, just want to make sure these will work for their local calls around the UK.

any input would be appreciated,

thanks.

Re: UK Local Dial Plan

You could install the UK dial plan & use that for calls from the phones in the branch site.

UK users are typically used to dialling a 9 for an outside line.

HTH,

Paul.

Re: UK Local Dial Plan

The problem with installing the dialplan is that you will have to use the 9.@ pattern with the appropriate numbering plan type and then use route filters for various dialing patterns.

Re: UK Local Dial Plan

Route filters only relate to the NANP. We don't use them in the UK.

Remember to install the dialplan on the pub & sub else your outbound calls will fail.

Re: UK Local Dial Plan

You can use route filters with any international numbering plan. You should use a route filter with the UKNP for local access. Blocking premium rate calls is probably a good idea too.

All you need to know about the UK Numbering Plan and route filters is in the tech note:

There's some errors in the above documents and the data is several years out of date.

Local Access

There is an error in the following text:

  In the UK, local subscriber numbers can be 5, 6, 7, or 8
  digits long, which depends on the area code. The UKNP contains
  four route patterns that overlap, for local access.

The text should read as follows:

  In the UK, local subscriber numbers can be 4, 5, 6, 7, or 8
  digits long, which depends on the area code. The UKNP contains
  five route patterns that overlap, for local access.

Add "4,". Change "four" to "five".

There is an item missing from the table:

Number Route Pattern
LOCAL-5-DIGIT [2-9]XXXX
LOCAL-6-DIGIT [2-9]XXXXX
LOCAL-7-DIGIT [2-9]XXXXXX
LOCAL-8-DIGIT [2-9]XXXXXXX

Add the extra line at the beginning of the table as follows:

Number Route Pattern
LOCAL-4-DIGIT [2-3]XXX
LOCAL-5-DIGIT [2-9]XXXX
LOCAL-6-DIGIT [2-9]XXXXX
LOCAL-7-DIGIT [2-9]XXXXXX
LOCAL-8-DIGIT [2-9]XXXXXXX

Add the new text "LOCAL-4-DIGIT [2-3]XXX" to the beginning of the table.

In the details after this text:

"For example, a gateway in a 2-digit area code with 8-digit subscribers has this filter:"

there is an error in the example code:

 (LOCAL-5-DIGIT DOES-NOT-EXIST AND
  LOCAL-6-DIGIT DOES-NOT-EXIST AND
  LOCAL-7-DIGIT DOES-NOT-EXIST)

The text should read as detailed below:

 (LOCAL-4-DIGIT DOES-NOT-EXIST AND
  LOCAL-5-DIGIT DOES-NOT-EXIST AND   LOCAL-6-DIGIT DOES-NOT-EXIST AND
  LOCAL-7-DIGIT DOES-NOT-EXIST)

Add "LOCAL-4-DIGIT DOES-NOT-EXIST AND" to the beginning of the example.

Extended National Toll Bypass

There are two errors in the following text:

  For example, calls from Reading (118) to Nettlebed (1491),
  Maidenhead (1628), Ascot (1276), Bracknell (1344), Aldershot (1252),
  Basingstoke (1256) and Newbury (1635) are charged at the local rate.

These two area codes changed name in 2003:

  • 01491: Nettlebed changed name to Henley-on-Thames.
  • 01276: Ascot changed name to Camberley.

The text should read as follows:

  For example, calls from Reading (118) to Henley-on-Thames (1491),
  Maidenhead (1628), Camberley (1276), Bracknell (1344), Aldershot (1252),
  Basingstoke (1256) and Newbury (1635) are charged at the local rate.

Correct the names for these two area codes.

The following text is incomplete:

  The OR statements appear when you add a new Clause to the filter.
  See Appendix D - Five-digit Subscriber Numbers for lists of area
  codes with 5-digit subscribers.

The corrected text should read as follows:

  The OR statements appear when you add a new Clause to the filter.
  See Appendix D - Five-digit Subscriber Numbers for lists of area
  codes with 5-digit subscribers and Appendix E - Four-digit
Subscriber Numbers for lists of area codes with 4-digit subscribers.

Correct the text.

Appendix A - UK PSTN Numbering Overview

The following text is incomplete:

  The UK PSTN does not have a uniform structure like the NANP.
  Area codes can be 2, 3, 4 or 5 digits; subscriber numbers can
  be 5, 6, 7, or 8 digits; and service codes can be 3, 4, 5, or
  6 digits. National numbers can be 10 or 11 digits (including
  the leading 0).

The corrected text should read as follows:

  The UK PSTN does not have a uniform structure like the NANP.
  Area codes can be 2, 3, 4 or 5 digits; subscriber numbers can
  be 4, 5, 6, 7 or 8 digits; and service codes can be 3, 4, 5, or
  6 digits. National numbers can be 10 or 11 digits (including
  the leading 0) and there are two 8 digit numbers (0800 1111 and
  0845 4647).

Add "4,". Add wording about the two 0800 and 0845 special cases.

In the following text:

"These are the rules for geographic numbers:"

there are some minor changes to make towards the end of this list:

  •   2-digit area codes have 8-digit subscribers.
  •   3-digit area codes have 7-digit subscribers.
  •   4-digit area codes have 6-digit subscribers.
  •   Some 4-digit area codes have both 5- and 6-digit subscribers.
  •   5-digit area codes have 5-digit subscribers.
  •   Some 5-digit area codes overlap with 4-digit area codes.

The corrected text reads as follows:

  •   2-digit area codes have 8-digit subscribers.
  •   3-digit area codes have 7-digit subscribers.
  •   4-digit area codes have 6-digit subscribers.
  •   Some 4-digit area codes have both 5- and 6-digit subscribers.
  •   5-digit area codes have 5-digit subscribers.
  •   One 5-digit area code has both 4- and 5-digit subscribers.
  •   All 5-digit code areas overlap with 4-digit area codes.

The wording is changed in one rule and there is an additional rule.

Geographic Number Examples

Two examples are missing from the table:

Access Area Code Subscriber Place
0 16977 XXXXX Brampton 5-digit
0 16977 XXXX Brampton 4-digit

Add the above examples to the table.

The Brampton 016977 area code has both four-digit and five-digit subscriber numbers.

National Numbers

These new number ranges are missing from the table:

Access SABC Type Length
0 300/302/303/306/330/333/343/344/345/370/371/372 UK wide 11

Add this extra number range.

The following table entry contains an error:

Access SABC Type Length
0 55X/58X Corporate 11

The correction is as follows:

Access SABC Type Length
0 55 Corporate 11

Correct the data for this number range.

The following number ranges have changed since 2003:

Access SABC Type Length
0 77X/78X/79X Mobiles 11

This entry should read as follows:

Access SABC Type Length
0 71XX*/72XX*/73XX*/74XX/75XX/7624/77XX/78XX/79XX Mobiles 11

Add the new number ranges.

*Note: 71XX, 72XX and 73XX are not yet in service.

The following number ranges have changed since 2003:

Access SABC Type Length
0 844/845 Local Rate 11

This entry should read as follows:

Access SABC Type Length
0 842/843/844 Special Rate 11
0 845 Lower Special Rate 11

Correct the data for this number range.

The following number ranges have changed since 2003:

Access SABC Type Length
0 870/871 National Rate 11

This entry should read as follows:

Access SABC Type Length
0 870 Higher Special Rate 11
0 871/872/873 Lower Premium Rate 11

Correct the data for this number range.

There is no such tariff as "local rate". This entry:

  NHS Direct—08454647 (local rate)

should be reworded to something like:

  NHS Direct—0845 4647 (Lower Special Rate)

Correct the wording.

Service Numbers

This new number range is missing from the table:

Service Codes Services
116XXX National Helplines

Add this extra number range.

Appendix B - Filter Categories

There is one example missing from the following data:

Category Numbers* Example

AREA-CODE

2, 3, 4, or 5 digits 20, 161, 1208

This entry should read as follows:

Category Numbers* Example
AREA-CODE 2, 3, 4, or 5 digits 20, 161, 1208, 15395

Add ", 15395" to the list.

There is an error in the following data:

Category Numbers* Example
SUBSCRIBER 5, 6, 7, or 8 digits -

This entry should read as follows:

Category Numbers* Example
SUBSCRIBER 4, 5, 6, 7, or 8 digits -

Add "4," to the list.

This new number range, allocated in 2009, is missing from the table:

Category Numbers* Example
NATIONAL-HELPLINES 6 digits 116123

Add this extra number range.

The following number ranges have changed since 2003:

Category Numbers* Example
LOCAL-RATE-ACCESS 844 or 845-
LOCAL-RATE-SUBSCRIBER 7 digits 7766554
NATIONAL-RATE-ACCESS 870 or 871 -
NATIONAL-RATE-SUBSCRIBER 7 digits 1112223

The new allocations are as follows:

Category Numbers* Example
LOCAL-RATE-ACCESS 842, 843, 844 or 845 -
LOCAL-RATE-SUBSCRIBER 7 digits 7766554
NATIONAL-RATE-ACCESS 870, 871, 872 or 873 -
NATIONAL-RATE-SUBSCRIBER 7 digits 1112223

Add the additional number ranges.

Note: In the other Cisco UK Numbering Plan document, these are  referred to as: LOCALRATE-ACCESS, LOCALRATE-SUBSCRIBER,  NATIONALRATE-ACCESS and NATIONALRATE-SUBSCRIBER with only one hyphen.

Note: It is now illegal in the UK to use the terms "local  rate" and "national rate" to describe these numbers in advertising as the price of calling them is higher than calling a normal geographic number.

These new number ranges, allocated in 2008, are missing from the table:

Category Numbers* Example
UK-WIDE-ACCESS 30X, 33X, 34X, 37X -
UK-WIDE-SUBSCRIBER7 digits222 3333

Add these new number ranges.

The following number type is missing from the table:

Category Numbers* Example
LOCAL-4-DIGIT 4 digits -

Add this extra data to the table.

These four-digit subscriber numbers are used in the 016977 area code.

Tag Combinations

The following tag combination is missing from the list:

  LOCAL-4-DIGIT

Add this tag data.

Appendix D - Five-digit Subscriber Numbers

5-digit Area Codes with 5-digit Subscribers

The data for 5+5 format numbers is incomplete and some area codes are linked to the wrong place names:

Location Area Codes
Dumfries 13873
Hornby 15242
Kendal 15394 15395 15396
Wigton 16973 16974
Penrith 17683 17684 17687
Gosforth 19467

The corrected data is as follows:

Location Area Codes
Langholm 13873
Hornby-with-Farleton 15242
Hawkshead 15394
Grange-over-Sands 15395
Sedbergh 15396
Wigton 16973
Raughton Head 16974
Brampton 16977
Appleby-in-Westmorland 17683
Pooley Bridge 17684
Keswick 17687
Gosforth 19467

Correct the data for these number ranges.

4-digit Area Codes with Mixed 5-digit and 6-digit Subscribers

The following number ranges have changed since 2003 and should be DELETED from the table:

Location Area Codes 5-digit Subscriber Number Ranges
Forfar 1307 8[2-4]XXX DELETE THESE
TWO ENTRIES
Kircudbright 1557 50XXX

These area codes were upgraded to use only 6-digit subscriber numbers at least several years ago.

The following number ranges were mis-classified by Ofcom for many years and should be DELETED from the table:

Location Area Codes 5-digit Subscriber Number Ranges
Wigton 1697 7[23]XXX DELETE THIS ENTRY

This entry should show the 4-digit subscriber numbers found in the 016977 Brampton area code.

This data therefore belongs in a different table and in a different format: e.g. "16977 [23]XXX". See the final item.

The following number ranges have changed since 2003:

Location Area Codes 5-digit Subscriber Number Ranges
Buxton 1298 2[2-7]XXX 7[0-47-9]XXX 8[3-5]XXX

The correct data is as follows:

Location Area Codes 5-digit Subscriber Number Ranges
Buxton 1298 2[2-8]XXX 7[0-47-9]XXX 8[3-5]XXX

The part "[2-7]" changes to "[2-8]".

The following number ranges have changed since 2003:

Location Area Codes 5-digit Subscriber Number Ranges
Alton 1420 2[23]XXX 8[02-9]XXX

The correct data is as follows:

Location Area Codes 5-digit Subscriber Number Ranges
Alton 1420 2[23]XXX 8XXXX

The part "[02-9]" changes to "X".

The following number ranges have changed since 2003:

Location Area Codes 5-digit Subscriber Number Ranges
St. Austell 1726 6[13-7]XXX 7[0-7]XXX

The correct data is as follows:

Location Area Codes 5-digit Subscriber Number Ranges
St. Austell 1726 6[13-9]XXX 7[0-7]XXX

The part "[13-7]" changes to "[13-9]".

The following number range is missing from the table:

Location Area Code 5-digit Subscriber Number Ranges
Penrith 1768 88[2-46-8]XX

The above number range needs to be added to the table.

The following area codes changed name in 2003:

  • 01276:  Ascot             changed name to  Camberley.
  • 01461:  Annan            changed name to  Gretna.
  • 01488:  Great Shefford changed name to  Hungerford.
  • 01562:  Stourbridge     changed name to  Kidderminster.
  • 01744:  Rainford          changed name to  St Helens.
  • 01963:  Templecombe  changed name to  Wincanton.

Correct the data for these number ranges.

There's a spelling mistake in the table:

  • 01557:  Kircudbright  should be Kirkcudbright.

Correct the spelling for this area.

A new section is needed, listing the details of 4-digit subscriber numbers:

Appendix E - Four-digit Subscriber Numbers

5-digit Area Codes with Mixed 4-digit and 5-digit Subscribers

Numbers beginning either 0169772 and 0169773 are in a 5-digit code area and have a 4-digit subscriber number:

A new table is needed as follows:

Location Area Code 4-digit Subscriber Number Ranges
Brampton 16977 [23]XXX

Add a new table to show the data for this number range.
