1. Introduction




2. Differences between Sipura SPA-2100 and Sipura SPA-2002

Sipura SPA-2100 also connects analog telephone adapters or fax machines with IP based data networks. The difference between Sipura SPA-2100 and Sipura SPA-2002 is that Sipura SPA-2100 has two RJ11 ports for connecting to existing telephone analog adapters, fax or PBX systems and two RJ45 Ethernet ports, whereas Sipura SPA-2002 has one RJ45 Ethernet port. Each one of the RJ11 ports can be configured independently from each other. One Ethernet port is for a router and the other port is for connection to a computer or another device in a local network. Sipura SPA-2100 guarantees precise and high-quality voice communications in different network conditions. The perfect quality of the voice is due to the new modern algorithms for decoding the voice.

The Sipura SPA-2100 eliminates the NAT problem by being both a router and a SIP adapter, which allows it to use your public IP address in SIP messages. The most common NAT problem is one-way audio (the other person can hear you, but you can't hear him). If your Sipura SPA-2100 is plugged directly into your DSL/cable modem and you have one public IP address (typical situation), then your Sipura SPA-2100 will use the public IP address (rather than a private IP address that would be assigned if a typical home router was in between the DSL/cable modem and the SIP adapter), which eliminates NAT problems.

The Sipura SPA-2100 also has a couple more relatively minor benefits: T.38 (QoS for faxes), and G.729 works simultaneously on both lines (which means that if you have a typical 128 kbps uplink, you can make two phone calls and browse the Internet all at the same time).

4. Prerequisites








5. Asterisk PBX configuration



First, you need to register a user in the sip.conf file. In our case we are registering the user test, to use for line1 and user test2 for line2. You have to also set the password(secret) - in our case test for line1 and test2 for the second line.

Type=friend means that this user can make and receive calls. Secret=test and Secret=test2 - password test for line1 and test2 for line2. Host=dynamic means that the IP is not static but dynamic through a DHCP server. Allow=all means that the line which this user will use supports all audio codecs. Context=test - this shows that this user is working with the extensions in this context of the configuration file extensions.conf.





The first line in the context [test] shows that if somebody dials the number 102 his call will be connected with the user test through SIP. In our case this user is set for line 1. The next line says that if the conversation is over then Asterisk has to hang up the line.

Do the same if you want to use line 2. In our example we do this with the number 104. If somebody dials 104, his call will be connected with the user test2 through SIP. Again, it’s good to add an extension for a hanging up in order to be sure that when the conversation is over the Asterisk PBX will hang up the line. You can see a screenshot of extensions.conf below.



6. Configuration



IVR Interface:











































• From the WAN port:





The welcome screen and the first option is "Status". On this screen you can see the Product Name and Serial Number of the device, the MAC address, also the current LAN and WAN IP address, Gateway, Domain name, Netmask and the Primary and Secondary DNS, etc.:

The second option is "Wan Setup". Here you can change the Connection Type(DHCP, Static IP, PPPoE, PPPoE with DHCP, or DHCP with PPPoE, you can change the Static IP Address, the Gateway and the Netmask address. PPPoE Settings also can be changed here(Login Name and Login Password prompt, Optional Settings are for setting up the Hostname, Domain Name, Primary and Secondary DNS and the Mode of DNS Query(Parallel or Sequential):


There is "Advanced" option in the right most part of the screen, which allows you to make some advanced settings - "Lan Setup' and 'Application".

The "Lan Setup" section includes the following options: changing the LAN IP Address, LAN Netmask, Enabling or Disabling the DHCP Server, changing the DHCP Lease Time, choosing the starting IP Address if DHCP Server is Enable, etc. You can see these options on the screenshot below:


Details of the options of that section are as follows:


1) LAN IP Address is the IP Address used by the LAN(PC) port, the default IP Address is 192.168.0.1.
2) LAN IP Mask is the Network Mask used by the LAN Port, the default Network Mask is 255.255.255.0.
3) Enable DHCP Server is option that allows you to Enable or Disable the DHCP Server, the default value is set to Enabled.
4) DHCP Lease Time is the the time used by the DHCP Server to distribute IP Address to the clients. The default value is "24h"
5) DHCP Client Starting IP Address is the initial IP Address which will be given to the clients. The default value is 192.168.0.2.
6) Number of Client IP Address is the maximum number of IP Addresses that can be distributed to clients. The default value is "50"


1) Enable - Enable or Disable, by default it is "No"(disabled).
2) Host MAC Address is for entering the MAC Address of the specified device. This field is empty by default.
3) Host IP Address is where you must enter the IP Address, which you want to assign to the specified device.
One note here: The Host IP Address should be an IP Address which is not in the range used for the distribution Addresses.

The "Application" section is for Port Forwarding, DMZ(Demilitarized Zone, it is used to secure an internal network from external access), System Reserved Ports Range.



The entries which you can use for Port Forwarding are twenty. The options are:
1) Enable - Yes or No, by default it is "No"
2) Service Name is optional. It is used to identify this entry with a name.
3) Starting Port is the initial Port of the Forwarded Port range.
4) Ending Port is the ending Port of the Forwarded Port range.
5) Protocol - you can choose between TCP, UDP or Both protocols for use. The default value is "TCP".
6) Server IP Address is the target Host that the traffic is forwarded. The default value is "0".


1) Enable DMZ - Enable or Disable, by default it is "No"(disabled)
2) DMZ Host IP Address - the DMZ Server IP Address. The default value is "0"




Note: The "Starting Port" has a fixed value of 10000. For example, by default the value is set to 50000, thus the system reserved ports range will be [60000,60256].


1) Starting Port - the starting port of the system reserved port range. The default value is "50000"
2) Number of Ports reserved - total ports reserved by the system, by default it is "256".

Voice Section

The second general option is "Voice". On this screen you can see the Product Information, System current Status, Line 1 Status, Line 2 Status. You also can change the User Password, Syslog Server, RTP ports range, the Time Zone, Local Date, change the SIP settings for Line 1 and Line 2 and configure the settings for User 1 and User 2.

The next few screenshots shows in short these settings in the "Voice" section.

On this screenshot you can see the Product Name, MAC Address, Current Time, Line 1 Status information and Line 2 Status information.


You can change the User Password, Syslog Server, the Debug Server and also the Debug Level.


You can change the RTP Ports range and also the Response Status Code.


Here you can change the Act Codes, Current Time Zone, Local Time.


You can make changes for the Line 1 with the follow options: SIP Port, to set up a Proxy Server, Registration needed or not, the time of expires the registrations. Also the preferred audio codec, etc.


The same options as the aboves, but for Line 2.


Here you can change Forward settings, the Distinctive settings, and the Ring settings for User 1.


The same options as above, but for User 2.

7. Firmware upgrade

It is good to have your devices always updated to the latest available firmware.
Follow the steps below for upgrading:
1) Go to the Official Sipura web page.
2) Download the latest firmware.
2) After you download the package, unzip it and choose between .exe and .bin file to use according to your Operating System. If you use Windows use upg-spa2100-x-x-x.exe file. If you use UNIX-like Operating System, you have to use the .bin file - spa2100-x-x-x.bin.
3) There are two ways for upgrading your firmware. The first one is via TFT, the second is via HTTP.









Release Notes for Firmware 3.3.6:


*** Since firmware 3.2.9(b) ***

* T38 Redundancy made configurable via per-line parameter FAX_T38_Redundancy.
* Support NOTIFY "check-sync" event as NOTIFY "resync" event.
* Support <Mark All AVT Packets> option:
If set to "yes", all AVT tone packets (encoded for redundancy) will have the marker bit set. If set to "no", only the 1st packet will have the marker bit set for each dtmf event. Default is "yes" (compatible with old behavior).
* Changed default ring and call-waiting tone cadence to bellcore standard r1-r5 and cwt 1-4.
* Changed default ring to: 85V, 20 Hz (US std), and trapezoid waveform.

* If first record in a record-route header has an maddr
parameter that is specified as a hostname instead of an IP address, the SPA will not try to resolve it and use it to send the next request (within a dialog); it still uses the host portion of the record istead.
* Restric Source IP feature didn't work when both SRV and "Auto SRV Prefix" were enabled.
* nonce-count (nc) parameter not incremented when reINVITE to hold/resume inside a dialog.
* DMZ router feature didn't work.
