Connection establishment using CTLS has the following restrictions
(in contrast to LCR):
- If SLMA stations are seized, any active transfers of ringing, call forwarding no answer, call pickup groups and intercept cases are disregarded, provided the SLMA station is configured in the same PBX as the station used for CTLS or if the PBX where the SLMA station is configured is reached via CorNet-NQ.
- Hunting group number: Any attempt to reach a station by dialing the hunting group number is rejected if the station is configured in the same PBX as the station used for CTLS or if this PBX was reached via CorNet-NQ. Master hunting group: The master is seized if the hunting group number is dialed. The hunting group function is ignored, if the station is configured in the same PBX as the station used for CTLS or if this PBX was reached via CorNet-NQ.
- If an interim destination reached using CTLS is busy, the connection can only be reestablished, after the caller goes on-hook. Rerouting is not performed.
- A CTLS entry cannot be saved for number redial. Strings, and parts thereof, with a maximum length of 22 characters can be saved under destination and repertory keys.
- Callback on busy and free is not possible.
- During an active CTLS connection all third-party features such as consultation hold, transfer, broker's call, conference, etc.) are blocked for the dialing station.
- It is not possible to establish a CTLS connection from a third-party connection.
- The destination reached using CTLS cannot activate any third-party features during the connection if the destination is configured in the same PBX as the station using CTLS or if this PBX was reached via CorNet-NQ.
