Use the specific configuration guide below as an example to configure an SV8100 or SL11100/SL1000 PBX for connection to the service described above via SIP trunks.

Recommended Software Versions

SV8100: CCPU vC9.00 NEC-SV8100
SL1X00:

v4.0 NEC-SL1X00

System Programming

The following items should be changed – all other items are considered irrelevant and as such left as default. Screenshots are for example purposes only and will have been taken from the PBX under test but will apply to the other PBXs listed on the cover of the certificate. Any differences in programming will be documented where necessary.

Notes

  • DDIs can be configured if required, using the same procedure as for ISDN trunks
  • SIP calls are sent “en bloc”. This means that the External Call Inter digit timer (PRG21-01-03) must expire before the call is set up. This can be reduced, but will have an impact on ISDN trunks also. The user can dial # to indicate “end of dialling” instead if required.
  • CLI can be sent out using either 21-17 IP Trunk Calling Party Number Setup for Trunks or 21-19 IP Trunk Calling Party Number Setup for Extensions. If nothing is defined against the extension or trunk, or CLI is restricted through further programming, then no outbound CLI is sent.

Network Configuration

If Public IP addresses are assigned to the SV8100 IPLA and VoIP Gateways, then there should be no
network configuration required.
If there is one public IP address assigned, and NAT is used, it is necessary to configure Port Forwarding
on the router:

  • Port 5060 should be forwarded to the IPLA IP address
  • Port 10020 – 10275 should be forwarded to the VoIP Gateway IP addresses
  • NAPT should be enabled in PRG10-12-06 and the Public IP address should be entered into
    PRG10-12-07.

Known Limitations/Comments

  • The service uses “Networking Mode” which means that the system does not maintain a
    registration. This means that the system is unable to determine if the SIP server is available, and
    if it is acceptable to set up calls.
  • The service only supports codec G.711.
  • At the time of publishing the service does not support T38 fax mode. Should the carrier add this to the service it will not be added to the certificate until further testing has been completed.
