WLR / CPS FEATURE GUIDE

If you have a WLR (Wholesale Line Rental) or CPS (Carrier Pre-Select) service with us, we’ve created this handy guide to help you use BT’s call features.

BT use two different types of telephone exchanges to provide the Feature Line service, System X and System Y.
If you're not sure which exchange type you're on, please dial *#001# from your phone.
 
If the message you receive begins with the word "Sorry", you ‘re on a System Y exchange.

X & Y Exchange Issues

Unable to dial out
With FeatureLine Compact you need to dial 9 for an outside line.

Unable to set or use features
This could be because your telephone is not set to tone dialling and timed break recall. The line you are using may not be a FeatureLine. If only some features are affected check the user guide for the differences of the serving exchange.

Unable to cancel feature
Is the FeatureLine connected to Customer Network Access Equipment (Smart Box etc)? Some versions of this equipment may block # when dialled as a leading digit.

This is often reported as unable to cancel divert.

eg Set divert all calls *21* 9 tel number # is allowed because # is not a leading digit.

Cancel divert all calls #21# is not allowed because # is a leading digit.

Unable to call extension internally
Ensure that you have the correct extension number and that Divert is not active. Also check that the Hunt Group DND are active and check that the extension is on the same Business Group.

Unable to transfer call
Telephone not set to timed break recall. You cannot transfer between two telephones paralleled on the same FeatureLine.

Unable to transfer call using Call Waiting or Call Pick Up
If a call is answered using Call Pick Up or Call Waiting whilst engaged on another call, it will not be possible to use the transfer facility. It will be possible to toggle between the two calls by pressing Recall - 2, but in order to transfer, one of the calls will have to be cleared.

 One way transmission when using call transfer
Is the FeatureLine connected to the Customer Network Access Equipment (Smart Box etc)? Some versions of this equipment may block the outgoing transmission path when recall is used.

Please contact your supplier for advice.

Incoming calls ring wrong extension
This could be because the extension has divert active.

Incoming call to Hunt Group gives 'ring tone no reply' 
This may be because the Hunt Group call has been presented to an unmanned Hunt Group extension. If so, invoke Do Not Disturb (*261#) at the extension to overcome problem.

Unable to invoke divert to an External number
You may not have inserted 9 in front of the number when nominating telephone number.

Unable to use Call Pick-Up (*52#)
Call Queuing will be deactivated during the time in which a Hunt Group Divert (for all calls) is active.

Ring Back not working
The Other extension may be in a different Pick-Up group.

Call Offer not working
Call Offer will not operate if the user has a call in hold. You can use Transfer To Busy (System X or Y) or Call Offer Predetermined (System X only) as alternatives.

Call Waiting not working
Call Waiting is provided NON-ACTIVE on FeatureLine. Call Waiting is not available on extensions which are Hunt Group members on System X. Divert on Busy or Basic Divert will override the Call Waiting Facility. Conversely, Call Waiting cannot be invoked on an extension with Divert on Busy or Basic Divert active.

Specific to X Exchanges

Call Diversion and Hunt Group Do Not Disturb no longer provide interrupted dial tone
To prevent customer confusion, intermittent (interrupted) dial tone is no longer used to indicate an active Call Diversion or Do Not Disturb once Call Minder is provided on System X FeatureLines. This is because Call Minder uses intermittent dial tone to indicate new messages. The customer should therefore use the appropriate check or interrogation codes to verify operational status of these features as follows:

Internal call to Hunt Group extension number returns Busy Tone
If calls to DID number are OK, then the extension has Hunt Group DND active.

Unable to invoke divert
You could be using the wrong divert codes. If the extension is not a Hunt Group member, the 2 digit Call Diversion codes are used. If the extension user is a Hunt Group member, the 3 digit Hunt Group Diversion codes are used.

Hunt Group diversion not diverting internal callers    
Hunt Group extension Direct Inward Dialling (DID) numbers cannot be diverted on System X.

Unable to divert Hunt Group to internal extension number
Hunt Group diversion diverts the Hunt Group telephone number. It is not designed to divert internal calls.

All incoming Hunt Group calls ring one extension
You cannot set the hunt group divert to the extension your using to set the facility - you need to go to another hunt group extension.

Hunt Group Call Queuing not working
A member of Hunt Group has diverted Hunt Group to an extension in Business Group (using internal extension number). This is a useful feature for applying a night busy facility for connection to an answering machine.
