Open the VoIP Settings dialog to edit the settings required for making VoIP (Voice over IP) phone calls to other devices (e.g. SIP phones or soft phones), i.e. for placing phone calls using network connections instead of the telephone network. Since the voice data is transferred using the camera's Ethernet interface, calling the camera for remote-controlling does not require an ISDN line any more. Likewise, the camera can place (voice) phone calls to other SIP phones, soft phones (computer applications emulating a SIP phone), but also to regular telephones and mobile (cell) phones when using SIP providers.
Note: This feature is not available for Web and Basic models.
The term SIP telephony describes a mechanism for establishing voice connections using data networks instead of standard telephone networks. This method (also known as Voice over IP or short VoIP) allows establishing cheap phone connections (or free connections when connecting two SIP devices) using existing data networks. When using phone servers, VoIP also provides for easy integration of telephone and network services on the same network.
The MOBOTIX cameras support the SIP protocol (Session Initiation Protocol) that two SIP devices use to "discuss" the parameters of the voice connection. The voice data itself is exchanged using the Real Time Protocol (RTP); it is encoded using the audio codec both devices have agreed on.
The simplest case involves two devices that are using their IP addresses or DNS names to establish a SIP phone connection. This means that the calling device has to know the SIP address of the device it would like to call. A valid SIP address is composed of a user name, the "@" character and the IP address of the called device (e.g.
firstname.lastname@example.org). If this IP address also has a DNS name (this could be a router with an external IP address in larger networks), this address could look like this:
If SIP providers are used and the SIP accounts have been assigned telephone numbers, the devices can reach each other using the assigned phone numbers, just like calling regular telephones. SIP providers generally also provide connections to "regular" telephone numbers and mobile (cell) phones, usually at lower rates as compared to regular connections.
VoIP as a means of making phone calls is also interesting if ISDN is not available for making voice connections, but a network connection is possible.

0049for a phone number in Germany. The "0" of the prefix is dropped in most countries:
0049631xxxxxxx. Note that this depends on the country you are living in and make yourself knowledgeable at your SIP provider, for example.
You have two different options for configuring VoIP: The Quick Setup mode activates VoIP automatically, allowing you to place the first VoIP phone calls with a minimum of manual intervention. The Expert mode allows setting all parameters manually; you can thus use the extended VoIP features and adapt the camera to special network environments.
This section contains the general settings for VoIP telephony.
Use this option to either Enable or Disable the VoIP functionality.
Note: If you deactivate VoIP, the settings in this dialog are still stored in the configuration file of the camera and will remain available if you need them again.
|Hangup on Outgoing Calls||If this option is activated, the MOBOTIX camera will close an ongoing call if another call has been triggered and will play a sound file on its speaker if Call Status on Camera Speaker has been activated. If this is not the case, the camera will signal the ongoing call by blinking with all LEDs.|
If this option is enabled, the camera can dial several numbers simultaneously. The camera will establish the connection with the receiver that first accepts the call.
Note: When using SIP servers that are checking the source ports of the call requests against the source ports of the registration, this feature cannot be used as the ports will differ from the registered ones.
This section contains the parameters that the camera uses for making SIP connections. Using these parameters, the camera can establish SIP connection using SIP providers or direct connections to a SIP device with an IP address (or DNS name). See the Introduction to SIP Telephony section in this topic for more information.

|Registrar||Enter the server address for the camera to log on as SIP user.||Leave this field empty as it is not used. Registration with the SIP server is disabled.|
|SIP ID||Enter the SIP ID that you have registered or that you have been assigned during the registration process with your SIP provider. This entry usually corresponds to the User name.||Leave this field empty as it is not used.|
|SIP Password||Enter the password for the SIP ID that you have set during the registration process with your SIP provider.||Leave this field empty as it is not used.|
|Use as outbound proxy||If this option is enabled, the Registration server is used as the default SIP proxy for all outgoing SIP connections. This option should be enabled if you are using a SIP provider, since this option also activates authentication with the registration server.||Disable this option.|
|Registration expires after||The registration with the registration server expires after this time. In this case, the server will return a "user not reachable" message if you are calling the camera from your soft phone, for example. The camera will automatically renew the registration after this time.||Since registration has been deactivated anyway if no registration server has been specified, this parameter may be set to any value.|
These settings should only be changed if your network environment involves special mechanism for security (firewall, NAT routers, ...).
|Use router address
(M12, D12, M22M, D22M, Q22)
|Enable this option if you are trying to establish connections via a router or firewall that performs NAT (Network Address Translation) and set the External router address (see below).|
|Enable this option if you are trying to establish connections via a router or firewall that performs NAT (Network Address Translation). Make sure that you set the NAT Address or STUN Server according to the selected option (see below).|
|External router address
(M12, D12, M22M, D22M, Q22)
|Enter the external IP address or the DNS name of the router or firewall in this field. When contacting other SIP devices, the camera will name this as its reply address instead of the camera's own (private) IP address. The router/firewall has to redirect the voice and video data to the corresponding port of the camera.|
|External router address or STUN server address
|Enter the external IP address or the DNS name of the router or firewall or the STUN server address in this field. When contacting other SIP devices, the camera will name this address or the address received using STUN as its reply address instead of the camera's own (private) IP address. The router/firewall has to redirect the voice and video data to the corresponding port of the camera.|
|SIP port||Enter the SIP port that is to be used e.g. behind a firewall. Only change the standard port 5060 if this is is necessary. Make sure that the SIP ports of all devices are the same when trying to establish direct SIP connections (this is usually not required when using SIP providers).|
|Audio RTP port||This is the port that is used for receiving the audio data. You may need to change this setting for some SIP providers or firewall scenarios. If a router or firewall are used that perform NAT (Network Address Translation), the router/firewall will have to redirect this port to the camera.|
|Video RTP Port||This is the port that is used for receiving the video data. You may need to change this setting for some SIP providers or firewall scenarios. If a router or firewall are used that perform NAT (Network Address Translation), the router/firewall will have to redirect this port to the camera.|
|Audio Data Timeout||The camera hangs up the call if there is no incoming audio data during the time specified in this parameter.|
The parameters of this section control the output of voice messages via the phone connection and the camera speaker.
|Welcome Message for Inbound Calls||Switches the output of a welcome message when calling the camera on or off.|
|Welcome Message for Outbound Calls||Switches the output of a welcome message when the camera calls on or off.|
|Delay Before Welcome Message||The camera waits for the specified time after the recipient has accepted the call before playing back its welcome message.|
|DTMF Key Confirmation for Inbound Calls||Switches the voice output of the phone key pressed by the caller on or off.|
|DTMF Key Confirmation for Outbound Calls||Switches the voice output of the pressed phone key when the camera is calling on or off.|
|Call Status on Camera Speaker||Controls the output of sounds to signal the call status on the camera speaker (ring on inbound call, announcement on hangup or disruptions).|

|Setup OSD||Actives/deactivates the configuration menu of the On-Screen display.|
The camera can use one of the following audio codecs for transferring voice data. When the camera is making a SIP call, it will try to use the codecs in this order: GSM (M12, D12, M22M, D22M), PCMA, PCMU. If you would like to use only one codec, deactivate the other ones.
|Use PCMA Codec||The PCMA audio codec creates uncompressed audio data with 8 kHz and a-Law encoding; audio quality corresponds to ISDN. The actual bandwidth required by this codec is 86 kbps (10.4 kByte/s).|
|Use GSM Codec||
This audio codec is only available on M12, D12, M22M and D22M cameras.
It uses a lossy compression to reduce the size of the audio data; audio quality corresponds to GSM connections. The actual bandwidth required by this codec is 35 kbps (4.2 kByte/s).
|Use PCMU Codec||This audio codec corresponds to PCMA/G.711a except for encoding, which uses u-Law instead of a-Law.|
When using video telephony, the camera can adjust the size of the image and the data throughput rate of the video stream.
|Video||This option activates the transmission of video. If deactivated, the camera can only place or receive audio phone calls.|
|Video Size||You can select one of the sizes CIF (352x288 pixels) or QCIF (176x144 pixels) for the transmitted video image.|
|Video Bit Rate||Use this parameter to adjust the maximum data throughput rate of the transferred video data. By dynamically adjusting the image quality, the camera tries to stay below the selected value.|
|Preferred Video Codec||If possible, the camera will try to use the selected video codec for video telephony. This selection does not appear if the camera supports only one codec.|
This parameter controls the behavior of the camera's signal outputs when using video telephony.
|Signal Out Function 1 controls Signal Output||This sets the signal output of the camera controlled by the first signal output function (e.g. to switch the light on/off). You can also deactivate this function.|
|Signal Out Function 2 controls Signal Output||This sets the signal output of the camera controlled by the second signal output function (e.g. door opener on for a specific time). You can also deactivate this function.|
|Signal Output Timeout||This parameter sets the time for which the signal output stays activated after executing Signal Out control function 2.|
