ISDN Compatibility - Collect Call Blocking

Description
The Collect Call Blocking feature allows for either blocking incoming ISDN collect call from the trunk or
from the extension.
If an incoming ISDN call has a reverse charging information element in the setup message, the call is
treated as a collect call and the system can block (reject) the call. If the above information element is
not included in the setup message, it is treated as normal incoming call.
Conditions
• Collect Call Blocking works on both ISDN PRI and BRI lines.
• Selection of Collect Call Blocking follows both trunk base settings (PRG 14-01-46) and extension
base settings (PRG 20-09-09).
• Collect call via VRS/DISA allows only trunk base settings (PRG 14-01-46), extension base settings
are not usable.
• Collect call via DIL/DID/TIE allows both trunk base and extension base settings. To enable Collect
Call Blocking both settings have to set "On".
• Collect call via a normal incoming call allows both trunk base and extension base settings.
If one extension in a ring group is set for Collect Call Blocking, this feature works for all extensions
which belong to that incoming ring group.
• Even if the incoming collect call is blocked, SMDR prints a record as reject call.
