miniSIPServer is a SIP server for Windows and Linux systems.

Official website is https://www.myvoipapp.com or https://www.minisipserver.com.

Download URL is https://www.myvoipapp.com/download.

In above figure, there are some important network elements. Both A and C are SIP IP-Phone. B is a computer with a SIP client. A and B are in the same local network where miniSIPServer is installed. We name them as "local user". C is in another network and we name it as "external user". They are connected through internet.

In this network, we assume that C has registered to VoIP carrier network directly; A and B are local users(extensions) in local VoIP network. A is assigned an external line number. When a local user makes a call to external user, such as B calls C, we name this scenario as "out-group call".

Please refer to following table for details about this network:

Actors	IP Address	Local number (Extension)	External line number
miniSIPServer	192.168.1.100	-	-
A	192.168.1.101	101	2001
B	192.168.1.100	100	-
C	-	-	2002

miniSIPServer supports several different call scenarios. The dialing plan will be different in different scenarios. It is required that subscriber shall dial out-group prefix before the real number if he/she wants to call outside numbers. The default prefix is '9'.

Following table describes the dialing plan and its scenarios.

Caller number	Called number (destination)	How to dial	Example
A	B	B's local number	100
A	C	Out-group prefix + C's external line number	92002
C	A	A's external line number	2001
C	B	-	It is supported through "auto attendant" feature.
B	A	A's local number	101
B	C	Out-group prefix + C's external line number	92002 Note: the external line should be shared for other local users to make outgoing call.

By default, miniSIPServer has pre-set three local users. Their names are '100', '101' and '102', and their passwords are '100', '101' and '102'. Of course, we can add, modify and delete local users dynamically and it is very easy to do that.

Please click menu 'Data / Local users' to show local users information windows.

In this window, icons will be different for local users' different state.

Icon	State
	The user is off-line.
	The user is online now.

No-answer time	Integer	Indicate how long the call should be kept until the called party answers it.
Use specific external line for out-group call	Yes or no	If it is selected, a specific external line must be configured together. Then, this extension will use this specific external line to make out-group calls.
Limit max duration of outgoing call (seconds)	Integer	It limits the max duration of outgoing call and miniSIPServer will release the call automaticlly if it reachs the max duration.
Maximum concurrent calls	Integer	It limits how many calls this local user can process at the same time. If it is zero, that means this user cannot make outgoing calls and cannot receive any incoming calls.
Maximum concurrent outgoing calls	Integer	It limits how many calls this local user can make at the same time. If it is zero, that means this user cannot make outgoing calls.
Call right	Integer	Call right for different calls. In "dial plan / analyze called number" table, some called number prefixs can be configured with different call right, only the users who have specific call right can make such calls.

• Transition
• Refine caller number
• Refine called number
• Analyze caller number
• Analyze called number

Please refer to "Dial plan" document for more details about some important concepts of "dial plan" feature. Here, we only describe the details of its configurations.

"Transition" is used to change numbers, such as caller number, called number, and so on.

Please click menu "Dial plan / Transition" to show "Transitions" main window.

Item	Type or value	Description
Transition ID	Integer	Transition ID. It will be referred by other records.
Transition type	1: Add prefix	Add a prefix before current called or caller string. "Prefix / Replace string" item must be configured together.
	2: Replace	Replace target string with a specific string which should be configured in "Prefix / Replace string" item. The target string is confirmed by "start position" and "length" items.
	3: Delete	Delete a string which should be confirmed by "start position" and "length" items
Start position	Integer	The start position from where current transition will be done. Valid value is between 0 and 31. 0 means the first digit of the number.
Length	Integer	The target transition length. It indicates how many characters should be deleted or replaced. Valid value is between 1 and 31
Prefix / Replace string	String	The specific strings which will be added as a prefix or replace target strings.

Since 'transition' is a very important and useful element in dial-plan and analysis process, we give some examples to describe how to use it.

Example 1: Change "1234" to "Holly1234".

    Transition type = Add
    Prefix/Replace string = Holly

Example 2:Change "1234" to "34".

    Transition type = Delete
    Start position = 0
    Length = 2

Example 3: Change "1234" to "Holly34".

    Transition type = Replace
    Start position = 0
    Length = 2
    Prefix/Replace string = Holly

8.2 Refine caller number

Please click menu "Dial plan / Refine caller number" to show its main window.

Item	Type or value	Description
Group ID	Integer	A group of 'refine caller number' records. This ID will be referred by other records.
Caller number prefix	String	miniSIPServer use longest-match method to match caller numbers with this prefix. For example, there are two recrods whose 'caller number prefix' is '123' and '12', if the caller number to be analyzed is '1234', the record '123' will match it.
Transition ID	Integer	If current record matchs the caller number, this transtion id will be used to get transition type and change the caller number.

8.3 Refine called number

In "dial plan", if calls are routed to external lines or SIP trunks, we can use this function to refine their final called number in outgoing calls.

Please click menu "Dial plan / Refine called number" to show its main window.

Item	Type or value	Description
Outgoing group ID	Integer	This item is defined in external line or SIP trunk outgoing call configuration. This function will use it as index item to refine called numbers of their outgoing calls.
Called number prefix	String	miniSIPServer "dial plan" process will use this item with "outgoing group ID" item to match calls. If calls are matched, "dial plan" will refine their called numbers.
Transition ID	Integer	If current record matchs the call, this transtion id will be used to get transition type and change called number of current call.

8.4 Analyze caller number

Please click menu "Dial plan / Analyze caller number" to show its main window.

Item	Type or value	Description
Caller number prefix	String	Caller number prefixes string. miniSIPServer use longest-match method to match caller numbers with this prefix.
Transition ID	Integer	Transition id for current caller number prefix. The analysis will change caller number according to the transition configuration.
Dial plan	String	Dial plan name. The default value of dial plan is "default". We can indicate any other dial plan name for specific caller number ( or caller number prefix). In the next "analyze called number" configuration, the "dial plan" will be the key parameter.

8.5 Analyze called number

"Called number analysis" is core procedure in miniSIPServer dialling plan and analysis process. Its analysis result will change caller number or called number and get final routing for calls.

Click menu "Dial plan / Analyze called number" to show its main window.

Item	Type or value	Description
Dial plan	String	Dial plan name. Both "Dial plan" and "Called number prefix" are key parameter for this analysis process. With different "Dial plan", "called number prefix" can be same. With different "called number prefix", "dial plan" can be same. In "Analyze caller number", we can indicate different "dial plan" for different caller numbers, then we can configure different result with the same called prefix for different callers.
Called number prefix	String	The target called number prefix to be analyzed. miniSIPServer use longest-match method to match called numbers with this prefix.
Route Type	Local user (extension)	The call should be routed to local users.
	External line	The call will be routed to outside through an external line. If a specific external line is configured, the call will be routed through this specific external line.
	SIP trunk	The call will be routed to a specific SIP server which is indicated by "SIP trunk ID" . If it is selected, "SIP trunk ID" must be set together and it can be found and configured according to "SIP trunk".
	Routing group	The call will be routed to a routing-group. If it is selected, "Routing group ID" must be set together. Please refer to "routing-group service document" for more details.
	Intercept	Current call should be intercepted and released immediately.
Change called number	Yes or No	It indicates whether the called number should be changed. If it is selected, two important items must be configured at the same time. one is "Transition ID" used to change called number. Another is "Re-analyze after transition". If it is selected, it means analysis process should be done again after the called number is changed.
Refine caller number	Integer	whether caller number should be refined after this procedure. If it is zero, it is unnecessary to refine caller number. If it is not zero, miniSIPServer will try to refine caller number according to 'refine caller number' group configuration.
Call right	Integer	Call right for current record. If it is 0, that means no limitation, all local users can make calls with this prefix. If it is non-zero, that means only local users who have the call right can make calls with such prefix.
Limit max duration (seconds)	Integer(>=0)	The max duration of matched call. If timer expired, miniSIPServer will force to release the call automatically. '0' means no limitation.

We can see that miniSIPServer can route calls to different destinations according to different called prefix, dial plan, etc. It is very flexible for our VOIP deployments.

Please refer to services guide documents for more details. Here we only describe some configurations which can be shared or used by several services.

9.1 Lua services trigger

In miniSIPServer, there are several methods to implement service logic. Some services are fixed in miniSIPServer, such as hunting-group. Some services are written in IVR-XML, such as auto-attendant. Some services are written in Lua script, such as calling-card, DISA, etc. For advance users, Lua script is very flexiable and powerful. In fact, miniSIPServer core has provided a set of interface for Lua script.

Both our R&D team and our advance customers can use Lua script to implement complex or customerized services. We don't provide more details about Lua script, and only describe how to trigger a Lua service according to called number prefix of a call.

Please click menu "services / Lua services"

Item	Type or value	Description
Dial plan	String	The "dial plan" name for incoming calls. Different local users or SIP trunks can have different "dial plan" name. If they are not indicated, the default value is always "default".
Called number prefix	String	This prefix is used to match the called number of incoming calls. It follows the "maximum length matched" rule of dial plan feature. miniSIPServer will trigger different Lua service according to different "dial plan" and "called number prefix" of incoming calls, and you can use different called number prefix to trigger the same Lua service.
Description	String	Description of current record.
Lua module name	String	Base file name of Lua service. Please pay attention that it is just base file name and doesn't include directory path. System Lua files are stored in the sub-directory "lua/services" which can be found in the miniSIPServer install directory. Customerized Lua file should be saved in the "lua" sub-drectory of application data directory.

All audio files have been installed with miniSIPServer and stored in the sub-directory "mss_ann". For example, if miniSIPServer is installed in directory "d:/myvoipapp/minisipserver", the audio files will be installed in directory "d:/myvoipapp/minisipserver/mss_ann".

Below table lists all audio files and their contents. In your deployment, you can replace them with your own audio files. If you use your own audio files, they MUST be saved in 'custAnn' sub-directory which is in application data directory. Please refer to document "How to record my own audio?" for more details.

In miniSIPServer, audio file name must be "xxx.wav" format. "xxx" must be 8 characters and only 0-9 and a-f are valid. In fact, "xxx" is the exact audio ID in miniSIPServer.

WAV file MUST be 'CCITT A-law, 8KHZ, 8Bit, 7kb/sec' format.

Sometimes, some scenaios require miniSIPServer to do some special process which could be different with common requirements. In order to fit these requirements and don't effect common process, miniSIPServer use special variant parameters to control these special modifications or call flows, and these parameters are all stored in 'mss_var_param.ini' file.

By default, 'mss_var_param.ini' file is not included in miniSIPServer install package, so you cannot find it after you install miniSIPServer. If necessary, you need to create it manually and save it in the "config" sub-directory of miniSIPServer application directory. When miniSIPServer starts up, it will prompt where its application data directory is. Please refer to below figure.

For example, the application data path is 'C:\Users\Gilson\AppData\Roaming\minisipserver' on windows system, then the full path of 'mss_var_param.ini' file should be 'C:\Users\Gilson\AppData\Roaming\minisipserver\config\mss_var_param.ini'. On Linux systems, including Pi, if the application data path is '/home/pi/.minisipserver', then the full path of 'mss_var_param.ini' file should be '/home/pi/.minisipserver/config/mss_var_param.ini'.

'mss_var_param.ini' is a .INI format text file, you can use notepad or any other text editors to create, modify and save it. This file has .INI format as below:

[session name]
parameter name=paremeter value

For an instance, below is a demo parameter 'gVarGuiLang' whose session name is 'gui', parameter name is 'gVarGuiLang' and parameter value is '1'.

[gui]
gVarGuiLang=1

There are several session definitions which are used by different inner modules. Please refer to following details.

Session name	Description
ccf	Call-control module uses this session to change some special call flows, for example, to disable music-on-hold feature.
gui	Special requirements for GUI.
scp	Service-control-process modules use this session to change some features of special services, for example, to control service mode of voice-mail service.
sip	SIP modules use this session to change SIP flow or some default values in SIP stacks.
srf	Special-resource-function module uses this session to control special media process, for example, to change default language of audio file.
sys	Parameters are required to modify whole miniSIPServer system process.

This document will not discuss more details about paramters and their values because they could make wrong effect to whole system if you don't understand them very clearly, so please be careful. If you have special requirements, please discuss and confirm with our support team.
