| How to check External Transfer?
Just a thought - Have you considered Access Restrictions.
I've never worked with them, so I can't give you an hands on account, but I did find this........in 553-3001-305
Fully Restricted Service
There are three levels of Fully Restricted Service:
—FR2
• allowed to originate and receive internal calls
• denied access to TIE and Common Controlled Switching
Arrangement networks
• denied access to and from the exchange network, either by dialing,
through an attendant, or using call modification from an unrestricted
telephone
Call modification takes place when certain features are activated
while a call is in progress (e.g., Call Park, Call Pickup, Call Transfer,
Conference, or Night Answer).
—FR1
• allowed to originate and receive internal calls
• allowed access to TIE and CCSA networks
• denied access to and from the exchange network, either by dialing
through an attendant or by using call modification from an
unrestricted telephone
Note: In a networking environment, incoming and outgoing calls can be
extended, via call modification, to a telephone with CLS = FR1.
If a telephone with CLS = FR1 is in a Multiple Appearance DN (MADN)
arrangement, the call may be presented if at least one of the telephones has
CLS = UNR. Once the call is presented it will ring all telephones in the
MADN group. However, only UNR telephones can answer the call.
—FRE
• allowed to originate and receive internal calls
• allowed access to TIE and CCSA networks
• allowed access to and from the exchange network using call
modification from an unrestricted telephone
— denied access (either by dialing or through an attendant) to and from the
exchange network
Note: The FRPT prompt in LD 17 allows or denies access to incoming
calls for FRE CLS telephones. It allows FRE calls to Call Pickup, Night
Answer, and to receive modified calls.
The assignment of Incoming Call Indicator (ICI) keys allows the attendant to
recognize which calls are fully restricted:
— DF0 = calls from FRE, FR1, and FR2 CLS, and
— DL0 = calls from CUN, CTD, TLD, SRE, and UNR CLS.
Semi-Restricted Service (SRE)
— allowed to receive calls from the exchange network
— restricted from all dial access to the exchange network
— allowed to access the exchange network through an attendant or an
unrestricted telephone only
Toll Denied Service (TLD)
— allowed to receive calls from the exchange network
— allowed access to WATS trunks for toll calls using direct trunk access
codes, unless New Flexible Code Restriction (NFCR) is programmed to
deny certain digits
— denied from calls on Central Office/Foreign Exchange (CO/FX) trunks
where 0 or 1 is dialed as a first or second digit following a direct trunk
access code. Special numbers, such as 411, 611, and 911, are allowed by
default unless restricted specifically by NFCR.
— denied from toll calls on CO/FX trunks when BARS or NARS access
codes are dialed, unless NFCR tables allow the call
— allowed toll calls on WATS trunks using BARS or NARS access codes,
unless NFCR tables deny digits
— allowed access to the toll exchange network through an attendant or an
unrestricted telephone
— allowed toll calls and special number calls on TIE trunks, unless NFCR
tables specifically deny certain digits. Direct trunk access to toll calls on
TIE trunks is permitted, as well as BARS or NARS access.
Conditionally Toll Denied Service (CTD)
— allowed to receive calls from the exchange network
— allowed access to WATS trunks for toll calls using direct trunk access
codes, unless New Flexible Code Restriction (NFCR) is programmed to
deny certain digits
— denied from calls on CO/FX trunks where 0 or 1 is dialed as a first or
second digit following a direct trunk access code (special numbers
excepted). New Flexible Code Restriction tables can be used to deny or
allow certain calls on these routes.
— allowed access to toll calls on CO/FX/WATS trunks placed using BARS
or NARS or CDP access codes. NFCR tables, if programmed on the
routes, are ignored for CTD users dialing Electronic Switched Network
(ESN) access codes.
— allowed toll calls and special number calls on TIE trunks, unless NFCR
tables specifically deny certain digits. Direct trunk access is permitted as
well as BARS or NARS access. NFCR tables deny calls for these users
only if direct TIE trunk access codes are used.
Conditionally Unrestricted Service (CUN)
— allowed access for calls placed through Automatic Number
Identification (ANI) trunks
— denied access for all other types of outgoing calls
Unrestricted Service (UNR)
— allowed to originate and receive calls from the exchange network
The eight possible Class of Service access restrictions are described in
Table 3.
