Call Through

The Call Through Sequence

Call Through
This function also enables, e.g., field representatives to use the least cost routing function and
VoIP/GSM routing on the PBX. To prevent high costs when using mobile telephones, an inter-
national call be made by first calling the PBX and then connecting to the desired connection
from the PBX. The Call Through function also enables the direct redial of any telephone
number.
The Call Through Sequence
A Call Through call is carried out as follows:
• On his mobile phone, the user dials an external phone number that has previously been
defined for Call Through on the PBX.
• Based on the telephone number transmitted by the mobile phone, the PBX verifies whether
the caller is authorized for Call Through.
• If Call Through authorization has been granted, the PBX automatically takes the call and
signals this using a special tone.
• The user dials the desired telephone number on his mobile phone equipped with DTMF.
After successful verification based on the Call Through list and perhaps the least cost
routing table, the PBX then dials this number and a connection is established.
Note: The greatest cost savings is achieved when the PBX telephone
number has been entered – if available – as a preferred special telephone
number with the mobile communications provider.
