Overview 


The purpose of this guide is to describe the steps needed to configure the Toshiba CIX40 

IP PBX for proper operation in a SIP trunking application. Please note that this solution 

documents the basic configuration needed in the PBX and that the requirements of your 

specific SIP trunking environment may require modifications to the configuration steps 

provided in this document. 

Prerequisites 

SIP trunking information provided by the VoIP service provider: 

SIP proxy server IP address or DNS name. 

Trunking Direct Inward Dial (DID) phone numbers 

Calls to the trunking DID(s) are forwarded from the service provider to the 

wide area network (WAN) IP address of the EdgeMarc. There may be a 

single “Pilot” phone number used for all inbound calls and/or multiple DIDs 

depending on the service ordered. 

SIP authentication credentials (optional) 

Some SIP trunking service providers require a unique username and 

password to be supplied for IP PBX registrations and/or SIP signaling using 

P-Asserted Identity (RFC 3325). This knowledgebase solution provides the 

configuration steps for PBX registration mode. The Toshiba CIX does not 

support non-registration (static) mode. 

Toshiba CIX40 – Version AR5.20 MT037.00 

The Toshiba CIX does not have a built-in Auto Attendant. Auto Attendant and 

Voicemail are available as add-on units and are not covered by this guide. The 

external Toshiba Auto Attendant/Voicemail system supports both in-band and 

RFC2833 DTMF. The Toshiba CIX40 will pass through RFC2833 to connected 

systems.

Toshiba CIX40 IP PBX Configuration 

The steps below describe the minimum configuration required to enable the PBX to use a 

SIP trunk for inbound and outbound calling. 

The configuration described here assumes that the PBX is already configured and 

operational with station side phones using assigned extensions or DIDs. This 

configuration is based on Toshiba CIX40 version AR5.20 MT037.00.

Set up the Toshiba CIX40 IP PBX for SIP Trunk provisioning 

The CIX40 works well with the Toshiba IP5022-SD phones. 

The CIX40 PBX was shipped with 2 fixed IP addresses, 192.168.0.252/24 and 

192.168.0.253/24, for 2 Ethernet ports (inside the box). 192.168.0.253 is the IP address 

of the CIX40 processor and it is mainly used by the Network eManager (configuration 

GUI) for managing the PBX’s configuration. 192.168.0.252 is the IP address of the GIPU 

card that supports SIP trunking. The GIPU should be in the same subnet as EdgeMarc 

port 1 and use Edgemarc port 1’s IP address as its SIP server. All the phones 

communicate with the PBX via this IP address as well, using the Megaco VoIP protocol. 

Notes: 

You can install the Network eManager on either the Windows XP or 

Window 7 machines. Once the Network eManager is successfully 

installed, run http://localhost/emanager with Internet Explorer to invoke 

Network eManager for configuring the PBX. Network eManager will not 

work with other browsers. 

The IP5022-SD phones by default will need IP address assignment, 

EdgeMarc port 1 should have the DHCP server enabled by default. 

The PBX comes with pre-set 3-digit extensions (i.e.: 224 to 227) set up 

and each phone to have the Station ID configured to match one of these 

extensions. 

With the default IP address of 192.168.0.252, the GIPU card would not 

be able register with EM. This is because once EM is configured to be in 

the same subnet as the GIPU, its internal UA will have an IP address of 

192.168.0.252 also. This conflict must be resolved before the GIPU can 

successfully register with EM. As of this writing, although changing the 

UA’s address is possible, it may involve some complex procedures. To 

avoid this conflict in the lab setup, the GIPU’s IP address was changed 

from 192.168.0.252 to 192.168.0.251 for EM-PBX setup in the lab. 

To change the GIPU’s IP address from 192.168.0.252 to something else, 

invoke Network eManager and access the GIPU Configuration screen 

(IP-Telephony->L/M/G IPU Configuration). 

To change the PBX’s management IP address from 192.168.0.253 to 

something else, invoke Network eManager and access the IP 

Configuration screen (Maintenance->CIX Processor IP Address).

Invoke Network eManager (with Internet Explorer only) with 

“http://localhost/emanager” to get the Log In screen. Log in with “Administrator” as the 

User Name and “password” as the Password to get to the Home screen.

Go to the Card Assignment screen (System->Card Assignment) and note the Cabinet- 

Slot number of the GIPU card. 

This is the card that supports SIP trunking. In this example, the Cabinet-Slot number 

(or the Equipment number) of the GIPU is 0105. 


Page 11 of 27


Go to the Incoming Line Group screen (Trunk->ILG) to assign group number 8 for 

SIP calls set the DID Digits field to 4. 


Page 12 of 27


Go to the DID screen (Trunk – DID) to match the last 4 digits of each DID to one of the 

3-digit extensions. 

Note: To see which extensions have been pre-set for SIP trunking, access the PDN 

Table View screen (Station->Station Assignment->Basic->PDN Table View) to see 

which extensions are already present for the GIPU. 

If each phone has an assigned IP address and has its Station ID configured to match 

one of the pre-set 3-digit extension numbers, the IPT Data screen (IP-Telephony->IPT 

Data) should reflect that.

Go to the Service Assignment screen (IP-Telephony->SIP Trunking->Service 

Assignment) to assign Service #1 for the SIP Trunk ISP (represented by the SIP Trunk 

Service Kind Table Index ) and its associated channel group. 


Page 18 of 27


Go to the URI screen (IP-Telephony->SIP Trunking->URI) to decide which DID 

should register with EM. Only the DID with SIP URI Attribution set to “main” will be 

used to register with EM. The 'main' DID in this screen must be the pilot DID. The 

password for 'main' must match the password set for the Pilot DID. This is a 

configuration requirement; calls will not work if this is not set correctly. 


Page 19 of 27


Go to the L/M/G IPU Configuration screen (IP-Telephony->L/M/G IPU Configuration) 

for configuring the GIPU card (Cabinet-Slot number = 0105). The IPU Default 

Gateway Address should be set to the same as EM port 1’s IP address.

Go to the Flexible Access Code screen and configure 9 as the Line Group access 

code.(Optional) 


Page 21 of 27


Go to the Calling number screen (Trunk->Calling Number) to configure the same 

DID for registration as the calling number when the PBX places an outbound call. This 

will set the Caller ID to match the Pilot DID. This is a requirement for registration mode 

configuration. The only supported mode for the Toshiba CIX is registration mode.

Call Forwarding Busy is setup from the phones themselves: 

Press your extension button + #6041 + 3000# + 10 

#6041 = Call Forward Access Code sequence 

3000# = Internal Extension Number or 9 + destination DID # 

10 = Ring time in seconds before Call Forwards 

Call Park and Retrieve is built in already and preconfigured. 

To park a call: 

1. While on a call, press Park in Orbit (the IP5022-SD phone has no such button) or press Cnf/Trn 

+ #33. The LED flashes green (consultation-hold). If you were on an extension during the call, and 

you have line button on your telephone, the line LED will flash until the call is picked up 

(depending on programming). 

2. Specify the Park Orbit using one of the following: 

- Press * and the system automatically selects a General Park Orbit between 7000~7019. The 

chosen orbit appears on the LCD.
