1 INTRODUCTION
This document describes the configuration procedures required for the NEC SL1100 and SV8100 IP-
PBX ranges to make full use of the capabilities of IPVS SIP Trunking.
These NEC IP-PBX’s are come of the many access products that interoperate with IPVS. They use the
Session Initiation Protocol (SIP) to communicate with IPVS for call control.
This guide describes the specific configuration items that are important for use with IPVS. It does not
describe the purpose and use of all configuration items on the SL1100 and SV8100, for those details,
see the relevant NEC documentation.
Interoperability testing validates that the device interfaces properly with IPVS via the SIP interface.
Qualitative aspects of the device or device capabilities not affecting the SIP interface such as display
features, functionality and performance are not covered by interoperability testing. Requests for
information and/or issues regarding these aspects should be directed to manufacturer.

2 IPVS Source Numbering Requirements
Please note that the following prerequisites must be satisfied for successful deployment:
Any SIP call must present a number with a current registration on the IPVS platform in one or more of
the following headers of the SIP message transmitted by the IP-PBX (listed in order of significance):
1. Diversion
2. P-Asserted-Identity
3. Remote-Party-Id
4. From
If you see a 604 SIP message back from IPVS then the device is not presenting the correct CLI to the
IPVS platform or the account is not present on the IPVS platform.
SIP Trunking DDI Users must have an active Public Number (DDI) on the IPVS Platform.
Legacy PBX users/extensions (who do not have a SIP Trunking User account provisioned) must present
the SIP Trunk Group number or ‘Bearer Number’ as their outbound CLI for calls to be able to traverse
the IPVS platform.

3.1 Caveats
Forwarding
When a call is forwarded by a SL1100/SV8100 user/device regardless of whether it has a specific CLID
setup the default CLID for the system is always used in this scenario and therefore is what will be seen
by the destination of the forward.
Toolbar Hold and Call Control
Hold on PBX handset and Toolbar must be used together.
Off System Hold
When a hold request is sent from the IPVS platform to the SL1100/SV8100 and is not followed by an
update for Music On Hold the system will play its own hold music to the local user.
Codec Profiles
The codec profiles offered by the SL1100/SV8100 are predefined meaning the following:
The SL1100/SV8100 only offers one G711 type per profile so we recommend that this is set to A-law.
The G.729_PT profile will offer and therefore allow the use of G711 and G722 meaning that while
G729 is the primary codec it may not be used in all call scenarios.
The G.729_Fix profile will only offer G729 and therefore this will always be used.
T.38 Negotiation
Due to limitations with the current firmware the SL1100/SV8100 is unable initiate the renegotiation
of T.38 for a fax call. If the other party initiates the renegotiation the SL1100/SV8100 will accept this
and T.38 will be used. Where the SL1100/SV8100 attempts to renegotiate to T.38 the fax will
progress using G.711a pass-through with this associated limitations of this method.
Double Hold
Due to limitations with the current firmware if an external party is placed on hold by the
SL1100/SV8100 that party is then unable to in turn place the SL1100/SV8100 user on hold. This
means that any flows involving the SL1100/SV8100 user being placed on hold which include
transferring will fail.

Blind Transfer
Please note that when blind transfering to a CO party users should press the hash (#) key at the end of
the dialled digit string for the destination before pressing transfer so that the IP-PBX is instructed that
the dialling has ended and can setup the call.

4 SOLUTION CONFIGURATION
The following diagram shows an example of a typical deployment configuration with the NEC
SL1100/SV8100. Typically, the SL1100/SV8100 is placed at the customer premises with either
Analogue to IP handset connected/registered to it.
The SL1100/SV8100 registers the main line (or Trunk Group number) with the Trunk Group
configured on IPVS. This enables all PBX users to be implicitly registered with IPVS via the trunk group
number registration.

8 NEC IP-PBX CONFIGURATION
The following steps show how to program a NEC SL1100/SV8100 to interconnect with IPVS using SIP
Trunking.
The steps in this section assume that you are connected to the SL1100/SV8100 with the relevant
privileges using NEC’s PCPro application and at the Advanced Programming Level. They also assume
that you have prior knowledge of PCPro and the setup of a NEC PBX using it.
For more details on the PCPro application and configuration of a SL1100/SV8100 PBX please consult
the relevant NEC documentation.
NOTE:
Before installing and configuring the NEC SL1100/SV8100, ensure that you read the
NEC Safety and Compliance Information and any other related NEC documentation.
The configuration steps discussed in this section have been taken from an example
configuration of a NEC SV8100. The steps are applicable to all SL1100 and SV8100
PBX’s discussed in the Device Capabilities and Known Interoperability Issues section of
this document.
It is assumed that the fundamental configuration of the SL1100/SV8100 has already been carried out.

8.1 SL1100/SV8100 Security
For public access network configurations IPVS recommends that the SL1100/SV8100 is placed behind
a router/firewall for security reasons.
This is particularly important in situations where the SL1100/SV8100 is issued a public IP making it
easily accessible from the internet; in these cases we recommend that the SL1100/SV8100’s position
is hardened to reflect this public accessibility as per standard industry practices.
In private access network configurations traversing a IPVS private solution i.e. BYON, though it is not
expected that the SL1100/SV8100 will be publically accessible we still recommend that steps are
taken to prevent unauthorised access to it.

Codec Setup
Under the Codec Setup page the following values should be set. If a value is not discussed then this
should be left as default unless advised otherwise.
Audio Capability Priority
The default value here is G.711_PT and where WAN bandwidth is
not an issue we recommend that this is left.
If you have a requirement to use G.729 as the preferred codec then
the G.729_PT or G.729_Fix profiles should be considered.
The G.729_PT profile will place G729 as the first choice codec in a
list of possible options meaning that G729 should be negotiation in
most call scenarios but is not guaranteed, this profile offers the best
compatibility with other SIP devices.
The G.729_Fix profile will only allow the use of G729 for calls but
reduces the systems compatibility with other SIP devices that do
not support G729.
DTMF Payload Number
101
DTMF Relay Mode
RFC2833
G.722 Maximum Audio Frame Size
20ms
Fax Relay Mode
Checked
