Overview

Network -> Host
Set Static
  • in section Host Name Configuration for Domain Name Configuration Source,
  • in section DNS Configuration for Configuration Source,
  • in section SNTP Configuration for Configuration Source,
  • in section Default Gateway Configuration for Configuration Source.

Network -> Interfaces
The network interfaces should be configured with unique LAN IP addresses. Currently only eth5 is used as uplink. Eth1-4 are not used yet (will be used as ports of a switch).
IMPORTANT:
Take care that all IP addresses are reachable by the OpenScape 4000 SoftGate.

SIP -> Gateways
Configure your SIP gateway now.
SIP gateway configuration:
For this example we use "Trunking" as the Gateway Name.
In section Gateway Configuration field Network Interface select Uplink.

Configuring the vHG 3550 gateway address (198.16.16.181):
In section SIP Default Servers enter the IP address to field Proxy Host.

SIP > Registrations
There are no endpoints in the trunking configuration, therefore registration is not necessary.
IMPORTANT:
As the Mediatrix gateway only supports native SIP (not SIP-Q), a registration mechanism is not provided for trunking.

System -> Hardware
Hardware configuration of the PRI card.
In section PRI Cards Configuration:
  • Select the Line Type (E1 or T1)
  • Select Isdn for Signaling

Call Router -> Route Config
The Mediatrix gateway's "Call Router - Route Config" setting is not used in the general scenario for CO trunks (especially not for differentiation based on E.164 number). Station number handling is usually configured in the OpenScape 4000 system (see OpenScape 4000 sample configuration for S2 interface).

It is assumed that the OpenScape 4000 transmits all dial patterns (subscr, national, internat) in E164 ISDN / international format (block dialing must be configured).
The example here refers to a location with ISDN number +49 (69) 7600-XXXXX.
IMPORTANT:
The longest number to be modified must be first with these criteria!

Outgoing calls from the OpenScape 4000 SoftGate to the CO Carrier

Between Mediatrix Gateway and the HG 3550 interface all numbers are send as E.164 International ISDN Numbers. This number format is signaled with a "+" at the beginning of each pattern.
Depending on the CO carriers requirements, the number format send to the ISDN interface may be modified to type of number "National" ("CO_outg_national") or "Subscriber" ("CO_outg_subscr").
The modification is executed for calling and called numbers.
Criteria/Transformation:
Therefore the following criteria/transformation is applied:
  1. E164 -> E164 or TONE -> TONE.

Incoming calls from the CO carrier to the OpenScape 4000 SoftGate

The same applies to incoming calls to the sip HG 3550.
The called number in the subscriber format is converted to international ("CO_inc_called") format. If the carrier transmits the called number in national format, the routing must be changed from "CO_inc_called (.+) +4969\1" to "CO_inc_called (.+) +49\1".
The incoming number (calling number) is modified depending on format via the routing entries "CO_inc_calling_subscr_to_4969…" or "CO_inc_calling_national_to_49…". Different rules apply to the calling number as to the called number because the called number is always the same (depending on the carrier either subscriber or national) but the calling number can be different (subscriber, national or international).
Criteria/Transformation:
Therefore the following criteria/transformation is applied:
  1. Calling E164 -> Calling E164 or Calling TONE -> Calling TONE and
    • Called E164 -> Called E164 or Called TONE -> Called TONE.
