Interconnection
A Gigaset T300 PRO / Gigaset T500 PRO interconnection is the linking up of several
Gigaset T300 PRO / Gigaset T500 PRO PABXs at various locations. A prerequisite for the
interconnection is that the locations are connected via virtual private networks (Site-to-
Site VPN recommended) or static IP addresses with the appropriate firewall configura-
tions. This is necessary as the interconnection depends on unfiltered IP communication
between the various locations.
Location details
Give the location an appropriate and unique name within the group. The name can con-
tain letters, number and underscores (umlauts and ß are excluded).
The
Prefix
field requires a number that prefixes the internal phone numbers of the PABX
within the group. The purpose of this is to avoid overlaps in internal phone number
ranges.
Example
: Two PABXs (A and B) both have internal numbers from 10 to 99. PABX A is given
the prefix 3 and PABX B 4. If a user from PABX A calls the user with the phone number 10
on PABX B using a function key, the system automatically predials the prefix 4, meaning
that 410 is dialled.
Important
Port 3090 must be enabled for TCP via the integrated firewalls for the interconnec-
tion.
Important
Only leave this field blank, when it is assured that all PABXs in the group have separate
phone number ranges.
Please note
When entering internal phone numbers for another PABX, the caller must enter the
prefix manually.
